Abstract
The impact of hydrogen (H2) producing magnesium (Mg) incorporation into minced beef meat (MBM) on the quality and safety of the product was investigated. The H2-producing Mg (H2-P-Mg)-incorporated MBMs were vacuumed (VP) and stored at 4 °C for 12 days. Other MBMs were vacuumed and gassed with H2 or N2. At the end of storage, the lowest browning index values were for H2 and H2-P-Mg samples. H2- PMg and VP methods generally decreased the counts of mesophilic and psychrotrophic bacteria and yeast molds and restricted the formation of thiobarbituric acid reactive substances and biogenic amines. Heat mapping, PCA, and multivariate analysis methods confirmed chemical analysis results. The volatile compounds were at their highest levels in the control samples at the end of storage, followed by H2, N2, H2-P-Mg, and VP samples. Using the H2-P-Mg method in MBM preparation could protect the quality characteristics and safety of the product during cold storage.

Abstract
The objectives of this research were to study the effect of UV irradiation on quality characteristics of mango juice during cold storage. Mango juice exposed to UV radiation was also used to determine zero-order and first-order kinetic models of microbial (total plate count, yeast and mold count, and Escherichia coli) reduction. According to the microbiological results, UV light at 120 J/cm2 caused a 5.19 log reduction. It was found that microbial inactivation of all tested microorganisms followed first-order kinetic model. The treatments did not differ significantly in terms of the quality metrics. L*, b*, pH, total soluble solid, total phenolic compound, total flavonoid content, and antioxidant activity as measured by the DPPH and FRAP assay all tended to decline during storage at 4 °C, whereas a*, ∆E, titratable acidity, total plate count, yeast and mold count, as well as the total plate count, had an increasing trend. During storage at 4 °C, UV irradiation increased the shelf life of mango juice by about 14 days compared to the control sample. In conclusion, this study demonstrated the potential of UV treatment as an alternative to thermal pasteurization for preserving mango juice quality and safety while also prolonging shelf life.

Abstract
BACKGROUND The global growth of pistachio production has prompted exploration into sustainable agricultural practices, on the application of humic substances such as fulvic acid in enhancing the quality of horticultural crops. The present study was carried out in Qom province, Iran, on 20 years old pistachio (Pistacia vera L. cv. Kaleh-Ghoochi) trees and investigated the impact of foliar spraying of fulvic acid at varying concentrations (1.5, 3, and 4.5 g L- 1) on the antioxidant and quality properties of pistachio. The different concentrations of fulvic acid were applied at two key stages: at the initiation of pistachio kernel formation (late June) and the development stage of pistachio kernel (late August), as well as at both time points. Following harvest at the horticulturally mature phase, various parameters, including total phenols, flavonoids, soluble proteins, soluble carbohydrate content, antioxidant capacity, and antioxidant enzyme activity, were assessed. RESULTS Results indicated that foliar application of fulvic acid, particularly at 1.5 g L- 1 during both late June and August, effectively increased phenolic compounds (31.8%) and flavonoid content (24.53%). Additionally, this treatment also augmented antioxidant capacity and heightened the activity of catalase (CAT) (37.56%), ascorbate peroxidase (APX) (63.86%), and superoxide dismutase (SOD) (76.45%). Conversely, peroxidase (POX) (41.54%) activity was reduced in fulvic acid-treated nuts compared with controls. Moreover, the content of chlorophyll (45%) and carotenoids (46.7%) was enhanced using this organic fertilizer. In terms of mineral elements, the increment was observed in zinc (Zn) (58.23%) and potassium (K) (28.12%) amounts in treated nuts. Additionally, foliar application of fulvic acid led to elevated levels of soluble carbohydrates and proteins in treated nuts. CONCLUSIONS In the present study, application of fulvic acid resulted in enhancement of antioxidant activity and quality traits of pistachio nut through an increase in total phenol, flavonoids, chlorophyll, carotenoids, K, Zn, and also activity of antioxidant enzymes. Therefore, use of fulvic acid emerges as a promising strategy to enhance the quality and nutritional attributes of pistachios, contributing to sustainable agricultural practices and improved crop outcomes.

Abstract
Forced degradation, also known as stress testing, is used throughout pharmaceutical development for many purposes including assessing the comparability of biopharmaceutical products according to ICH Guideline Q5E. These formal comparability studies, the results of which are submitted to health authorities, investigate potential impacts of manufacturing process changes on the quality, safety, and efficacy of the drug. Despite the wide use of forced degradation in comparability assessments, detailed guidance on the design and interpretation of such studies is scarce. The BioPhorum Development Group is an industry-wide consortium enabling networking and sharing of common practices for the development of biopharmaceuticals. The BioPhorum Development Group Forced Degradation Workstream recently conducted several group discussions and a benchmarking survey to understand current industry approaches for the use of forced degradation studies to assess comparability of protein-based biopharmaceuticals. The results provide insight into the design of forced degradation studies, analytical characterization and testing strategies, data evaluation criteria, as well as some considerations and differences for non-platform modalities (e.g., non-traditional mAbs). This article presents survey responses from several global companies of various sizes and provides an industry perspective and experience regarding the practicalities of using forced degradation to assess comparability.

Abstract
The effect of ultrasonic pre-treatment on moisture removal characteristics of ginger in a convective dryer was investigated. The slabs were dried by practicing sonication durations of 0, 15 and 30 min at different levels of the air temperature and velocity. Following increasing the sonication duration and air temperature, required time and energy to dehydrate the samples were decreased. The pre-treatment played important role in improving rehydration capability and surface color retention in the dried gingers. Content of the main volatile component (α-Zingiberene) was not influenced by the sonication. Mean values for the phenolic contents and antioxidant activity at sonication duration of 0, 15 and 30 min were determined to be 18.93, 18.15 and 17.49 GAE/g dry matter and 83.57, 78.33 and 74.58 %, respectively. The desired values for the temperature, velocity and sonication duration were revealed to be about 66 °C, 3 m/s and 20 min, respectively.

Abstract
During storage and processing, muscle proteins, e.g. myosin and myoglobin, will inevitably undergo degeneration, which is thus accompanied by quality deterioration of muscle foods. Some exogenous additives have been widely used to interact with muscle proteins to stabilize the quality of muscle foods. Molecular docking and molecular dynamics simulation (MDS) are regarded as promising tools for recognizing dynamic molecular information at atomic level. Molecular docking and MDS can explore chemical bonds, specific binding sites, spatial structure changes, and binding energy between additives and muscle proteins. Development and workflow of molecular docking and MDS are systematically summarized in this review. Roles of molecular simulations are, for the first time, comprehensively discussed in recognizing the interaction details between muscle proteins and exogenous additives aimed for stabilizing color, texture, flavor, and other properties of muscle foods. Finally, research directions of molecular docking and MDS for improving the qualities of muscle foods are discussed.

Abstract
Several publications have recently proposed NMR spectroscopy to evaluate the critical quality attributes (CQA) of pentosan polysulfate sodium (PPS), the active ingredient of Elmiron™ approved to treat interstitial cystitis. PPS is a polymer of sulfated β(1-4)-d-xylopyranose residues randomly substituted by 4-O-methyl-glucopyranosyluronic acid, containing, beyond the main xylose-2,3-O-disulfate repetitive unit, some minor residues that can be marker of both the starting material and preparation process. In the present study we assigned some previously unknown cross-peaks in 1H-13C HSQC NMR of PPS related to its minor sequences adding additional details to its CQA. Four anomeric cross-peaks related to glucuronate-branched xylose and different sulfation pattern as well as the preceding xyloses were identified. Two minor process-related signals of monosulfated xyloses (unsubstituted in position 2 or 3) were also assigned. The isolation of a disaccharide fraction allowed the assignment of the reducing end xylose-α/β as well as the preceding xylose residues to be corrected. Additionally, the oversulfation of PPS allowed detection of the reducing end xylose-tri-1,2,3-O-sulfate. The newly identified cross-peaks were integrated into an updated quantitative NMR method. Finally, we demonstrated that an in-depth PPS analysis can be obtained using NMR instruments at medium magnetic fields (500 MHz/600 MHz), commonly available in pharmaceutical industries.

Abstract
The relationship between quality attributes and microstructure in strawberry pulp after pasteurization (PS), ultrasound (US), electron beam irradiation (EB), and high pressure (HP) treatments was investigated. The results showed that US treatment decreased the viscosity to the lowest by 80.15% and increased the a* value, cloudy stability, and contents of titratable acid, total soluble solid, organic acids, total phenols, total flavonoids, and total anthocyanins (TAC), as well as its antioxidant capacity, due to the decrease in particle size, the destruction of microstructure, and the release of intracellular compounds. US and EB treatments could maintain the volatile compounds. The greatest deterioration in TAC and volatile compound content was found in the pulp treated with PS and HP treatments. HP treatment was beneficial to the enhancement of apparent viscosity, organic acids, and soluble sugar. These results provided insights into the enhancement of quality attributes in strawberry pulp due to the microstructure change.

Abstract
l-asparaginase is a first-line medicine used for the treatment of acute lymphoblastic leukemia. Differing quality of marketed l-asparaginase biosimilars has been reported to adversely influence treatment outcomes. Herein, the quality of l-asparaginase biosimilars intended for clinical use was reviewed in sight of quality assurance parameters using English and Chinese language database searching, which provided information for possible improvements to the manufacture of this medicine. Ten articles met inclusion criteria, and quality attributes that measured potency, specific activity, purity and host cell proteins (HCPs) were identified. Biosimilars manufactured in high-income countries represented good quality in all aspects. Biosimilars manufactured in high-middle/middle-income countries, however, suggested poorer quality control particularly over removal of HCPs. Future work should now focus on establishing pharmacopeia monographs to establish equivalent quality assurance for l-asparaginase biosimilars manufactured between countries. Standardization of the quality profile, analytical methods and the limits of critical quality parameters, are essential to ensure appropriated efficacy and safety of clinical grade l-asparaginase.

Abstract
Bitter gourds were dried under varied drying conditions in a microwave assisted fluidized bed dryer, and the process was optimized using response surface methodology. Microwave power, temperature and air velocity were used as process variables for drying and the process parameters were varied between 360 and 720 W, 40-60 °C and 10-14 m/s, respectively. The responses determined for deciding the optimal criteria were vitamin C, total phenolics, IC50, total chlorophyll content, vitamin A content, rehydration ratio, hardness and total color change of the dried bitter gourd. Statistical analyses were done by using response surface methodology, which showed that independent variables affected the responses to a varied extent. The optimum drying conditions of 550.89 W microwave power, 55.87 °C temperature, and 13.52 m/s air velocity were established for microwave assisted fluidized bed drying to obtain highest desirability for the dried bitter gourd. At optimum conditions, validation experiment was done to ensure the suitability of models. Temperature and drying time plays an important role in the deterioration of bioactive components. Faster and shorter heating led to the greater retention of bioactive components. Taking the aforesaid results into consideration, our study recommended MAFBD as a promising technique with minimum changes in quality attributes of bitter gourd.

Abstract
This study aimed to explore the impacts of slightly acidic electrolyzed water (SAEW) treatment on the physiology, quality, and storage properties of postharvest carambola. The carambolas were immersed in SAEW with a pH value of 6.0, ORP of 1340 mV and ACC of 80 mg/L. Results demonstrated that SAEW could significantly reduce the respiration rate, inhibit the increase in cell membrane permeability, and delay apparent color change. Relatively higher contents of bioactive compounds and nutritional components, such as flavonoids, polyphenols, reducing sugars, sucrose, vitamin C, total soluble sugar, and total soluble solid, as well as higher titratable acidity were maintained in SAEW-treated carambola. In addition, SAEW-treated carambola exhibited a higher commercial acceptability rate and a higher firmness, but lower weight loss and peel browning index than control fruits. Our results indicated that SAEW treatment achieved high fruit quality and nutritional values, potentially contributing to improve storage properties of harvested carambola.

Abstract
Meat and meat products consumer behaviour is becoming less predictable. The objective of this review was to determine the attributes associated with the consumer's perception of quality and identify factors influencing the perception and consequent attitude. In conclusion, the findings showed that factors impacting nutritional quality, chemical and biological hazards, animal welfare, beliefs, and fraud could affect consumers' perception of how safe meat products are. Consumers positively perceive sensory attributes and recognize meat's nutritional value, still concerned with fat. Animal welfare and environmental impact have become significant drivers of consumer perception. The presence of chemical additives is a severe concern. Information received by consumers through media strongly influences perception and behaviour. The negative stigmatization of meat and meat products and beliefs often not scientifically-based shapes consumer perception. Their sensory impact and price frame the acceptance of animal production or processing modifications.

Abstract
Relationships amongst solvent retention capacity (SRC) profiles and quality characteristics of triticale cultivars were investigated. Superior triticale grains resulted into flours with preferable quality attributes for baking bread. Standard and supplementary SRC-values exhibited significant correlation with grain, flour, and dough quality. Positive correlations among sucrose-SRC with ash, pentosan, and ferulic acid (FA) contents were significant. The standard SRC-profiles along with metabisulfite-SRC (MBS-SRC) and ethanol-SRC exhibited significant correlation with damaged starch (DS) content. The ethanol-SRC demonstrated strong correlations with water absorption capacity, FA, and Dmax-value alveolab parameter. Triticale flours containing a higher amount of anti-parallel β-sheets and tyrosine exhibited higher lactic acid-SRC (LA-SRC) and gluten-performance-index (GPI). Positive correlations between sodium dodecylsulphate-SRC (SDS-SRC) and anti-parallel β-sheets percentages were noticed. The LA-SRC, GPI, MBS-SRC, SDS-SRC, and SDS+MBS-SRC were positively correlated with SDS-sedimentation, gluten index and negatively to sulfhydryl-groups content. Triticales having higher LA-SRC and MBS-SRC resulted in dough with higher strength and tenacity.

Abstract
This study aimed to investigate melanosis, quality attributes, and bacterial growth of freeze-chilled Pacific white shrimp (Litopenaeus vannamei) during 6 days of chilled storage, as well as the preservative effects of tea polyphenol on shrimp. The results showed that freeze-chilled storage retarded the growth of bacteria and the accumulation of putrescine in shrimp. The growth of spoilage bacteria Photobacterium and Shewanella were inhibited. However, freeze-chilled storage aggravated melanosis and lipid oxidation. The total volatile basic nitrogen (TVB-N) slightly accumulated in the thawed shrimp. The incorporation of tea polyphenol preserved freeze-chilled shrimp. Melanosis and lipid oxidation of shrimp were alleviated. The accumulation of biogenic amines, TVB-N, hypoxanthine riboside, and hypoxanthine were retarded. Meanwhile, the growth of spoilage bacteria Pseudoalteromonas, Photobacterium, Psychrobacter, and Carnobacterium were inhibited. Based on sensory analysis, the shelf-life of chilled, freeze-chilled, and freeze-chilled tea polyphenol shrimp were 4 days, 3 days, and 6 days, respectively.

Abstract
The hen's egg (Gallus gallus) is an animal product of great agronomic interest, with a world production of 70.9 million tonnes in 2018. China accounted for 35% of world production, followed by North America (12% of world production), the European Union (7.0 million tonnes, 10% of world production) and India (5.0 million tonnes, 7% of world production). In France, 16-17 billion eggs are produced annually (14.5 billion for table eggs) and more than 1 200 billion worldwide. In 2019, egg production increased by 3.3% compared to 2018, mainly due to the increase in Asian production, which has risen by 42% since 2000. Chicken eggs are widely used either as a low-cost, high nutritional quality food cooked by the consumer (more than 100 billion eggs consumed in Europe), or incorporated as an ingredient in many food products. The various production methods have changed considerably over the last 15 years with the consideration of animal welfare and changes in European regulations. In Europe, fewer and fewer eggs are produced in confinement and there has been a strong growth in the number of systems giving access to an outdoor run. In this review, we describe the different ways in which eggs are produced and processed into egg products to meet the growing demand for ready-to-use food products. We analyse the effect of this evolution of hen-rearing systems on the set of characteristics of eggs and egg products that determine their quality. We describe the risks and benefits associated with these new production methods and their influence or lack of influence on commercial, nutritional, microbial and chemical contamination risk characteristics, as well as the evolution of the image for the consumer. The latter covers the ethical, cultural and environmental dimensions associated with the way the egg is produced.

Abstract
ABSTRACT This study was conducted to investigate the inactivation of foodborne pathogens and the quality characteristics of fresh chicken breasts after UVC light-emitting diode (UVC-LED) treatment. Fresh chicken breasts were separately inoculated with Salmonella Typhimurium, Escherichia coli O157:H7, and Listeria monocytogenes at initial populations of 6.01, 5.80, and 6.22 log CFU/cm2, respectively, and then treated with UVC-LED irradiation at 1,000 to 4,000 mJ/cm2. UVC-LED irradiation inactivated the test bacteria in a dose-dependent manner. After UVC-LED treatment at 4,000 mJ/cm2, the populations of Salmonella Typhimurium, E. coli O157:H7, and L. monocytogenes on chicken breasts were decreased by 1.90, 2.25, and 2.18 log CFU/cm2, respectively. No significant changes (P > 0.05) were found in color, pH, texture, and thiobarbituric acid-reactive substances of chicken breasts following UVC-LED irradiation at doses ≤4,000 mJ/cm2. These results indicate that UVC-LED radiation is a promising technology for reducing the level of microorganisms while maintaining the physicochemical characteristics of poultry meat. HIGHLIGHTS

Abstract
ABSTRACT Plasma-activated water (PAW) is a new sanitizer that has received considerable attention for application in food industries. This research aimed to evaluate the effect of PAW on the inactivation of Shewanella putrefaciens and quality attributes of Yellow River carp (Cyprinus carpio) fillets. The carp fillet samples were immersed in sterile deionized water (SDW) or SDW activated by plasma discharge for 120 s (PAW120) for 1.5, 3.0, 4.5, or 6.0 min. After being treated by PAW120 for 6 min, the population of S. putrefaciens on carp fillets was significantly (P < 0.05) decreased by 1.03 log CFU/g. Compared with SDW-treated samples, the L* value of PAW120-treated carp fillets was increased and the a* value was decreased after PAW120 treatment, whereas there was no significant (P > 0.05) difference in the b* value. Compared with SDW, PAW120 caused no significant (P > 0.05) changes in sensory properties and texture attributes of carp fillets including hardness, springiness, gumminess, and cohesiveness. However, 6-min PAW120 treatment caused a significant increase in the lipid oxidation level and a decrease in the pH value of the carp fillets. This work provides a basis for the potential application of PAW in the preservation of aquatic products. HIGHLIGHTS

Abstract
Nanomedicine is a rapidly emerging field with several breakthroughs in the therapeutic drug delivery application. The unique properties of the nanoscale delivery systems offer huge advantages to their payload such as solubilization, increased bioavailability, and improved pharmacokinetics with an overall goal of enhanced therapeutic index. Nanomedicine has the potential for integrating and enabling new therapeutic modalities. Several nanoparticle-based drug delivery systems have been granted approval for clinical use based on their outstanding clinical outcomes. Nanomedicine faces several challenges that hinder the realization of its full potential. In this review, we discuss the critical formulation- and biological-related quality features that significantly influence the performance of nanoparticulate systems in vivo. We also discuss the quality-by-design approach in the pharmaceutical manufacturing and its implementation in the nanomedicine. A deep understanding of these nanomedicine quality checkpoints and a systematic design that takes them into consideration will hopefully expedite the clinical translation process. Graphical abstract.

Abstract
Lipid nanoparticles (LNPs) are increasingly employed to improve delivery efficiency and therapeutic efficacy of nucleic acids. Various formulation parameters can affect the quality attributes of these nanoparticle formulations, but currently there is a lack of systemic screening approaches to address this challenge. Here, we developed an automated high-throughput screening (HTS) workflow for streamline preparation and analytical characterization of LNPs loaded with antisense oligonucleotides (ASOs) in a full 96-well plate within 3 hrs. ASO-loaded LNPs were formulated by an automated solvent-injection method using a robotic liquid handler, and assessed for particle size distribution, encapsulation efficiency, and stability with different formulation compositions and ASO loadings. Results indicated that the PEGylated lipid content significantly affected the particle size distribution, while the ionizable lipid / ASO charge ratio impacted the encapsulation efficiency of ASOs. Furthermore, results from our HTS approach correlated with those from the state-of-the-art scale-up method using a microfluidic formulator, therefore opening up a new avenue for robust formulation development and design of experiment methods, while reducing material usage by 10 folds, improving analytical outputs and accumulation of information by 100 folds.

Abstract
When two therapeutic agents are combined in a single formulation, i.e., coformulated, the quality and safety of the individual agents must be preserved. Here we describe an approach to evaluate the quality attributes of two individual monoclonal antibodies (mAbs), designated mAb-A and mAb-B, in coformulation. The mAbs were fractionated from heat-stressed coformulated drug product (DP) by hydrophobic interaction chromatography. Each purified mAb fraction was then compared with mAb-A and mAb-B in their individual formulations from the same drug substance sources used to make the coformulated DP lot, which was subjected to the same stress conditions. Product variants were evaluated and compared by using several analytical tests, including high-performance size exclusion chromatography (HPSEC), reducing and nonreducing gel electrophoresis, ion-exchange chromatography, capillary isoelectric focusing, and peptide mapping with mass spectrometry. Intermolecular interactions in coformulated and photostressed DPs were studied by evaluating aggregates fractionated from coformulated DP by HPSEC. Aggregate fractions of coformulated DP contained dimers, but not coaggregates, of mAb-A or mAb-B. Moreover, extensive assays for higher-order structure and biological interactions confirmed that there was no interaction between the two mAb molecules in the coformulation. These results demonstrate that the two coformulated therapeutic mAbs had the same quality attributes as the individually formulated mAb-A and mAb-B, no new quality attributes were formed, and no physicochemical, intermolecular, or biological interactions occurred between the two components. The approach described here can be used to monitor the product quality of other coformulated antibodies.

Abstract
Plasma-activated water (PAW) has good liquidity and uniformity and may be a promising candidate to inactivate Penicillium italicum and maintain the quality attributes of kumquat. In this study, the effect of plasma-activated water (PAW) on the viability of Penicillium italicum on kumquat and quality attributes of PAW-treated kumquats were then systematically investigated to elucidate the correlation between PAW and kumquat quality attributes. The effects of PAW on fruit decay, microbial loads, and firmness of postharvest kumquats during the 6-week storage were also investigated. The results showed that the viability of Penicillium italicum was notably inhibited by PAW on kumquats. Moreover, PAW did not significantly change the surface color of kumquats. No significant reductions in ascorbic acid, total flavonoid, and carotenoids were observed in kumquats after the PAW treatment. Results from nitrate and nitrite residue analyses showed that PAW did not leave serious nitrate and nitrite residues after treatment. The decay analysis results demonstrated that PAW has the potential to control kumquat decay and fungal contamination as well as maintain the firmness of postharvest kumquats throughout 6-week storage. Transmit electron microscope observation confirmed that PAW could cause the surface sculpturing in the skin cell wall of kumquat. The information obtained from this research may provide insight into the utilization of PAW to fight against fungal infection during the storage of citrus fruit.

Abstract
Biosimilar approval relies on the comparability of quality attributes (QAs), for which information can be derived from regulatory or scientific communities. Limited information is known about whether these sources are consistent with or complementary to each other. The consistency and complementarity of QA reporting in biosimilarity assessments for adalimumab biosimilars approved by the European Medicines Agency in European public assessment reports (EPARs) and scientific publications was assessed. A classification of 77 different QAs (53 structural and 24 functional attributes) was used to assess the types of and information on QAs reported. Six adalimumab biosimilars were analyzed, for which the number of QAs reported in EPARs and publications varied (range = 47 [61%]-60 [78%]). The proportion of QAs consistently reported in both sources varied (range = 28%-75%) among biosimilars; functional QAs (mean = 21 QAs [88%]; range = 19-23) were more consistently reported than structural QAs (mean = 33 QAs [62%]; range = 27-34). The EPARs frequently reported biosimilarity interpretation without providing test results (9-57 QAs in EPARs versus 0-8 QAs in publications), whereas publications frequently reported both test results and interpretations (13-40 QAs in publications versus 0-3 QAs in EPARs). Both sources provided information on the biosimilarity of QAs in a complementary manner and the same biosimilarity interpretation of test results for reported QAs (mean = 90%; range = 78%-100%), with a small discrepancy in biosimilarity interpretations of a few clinically relevant QAs related to post-translation modifications and biological activity. Comprehensive reporting of QAs can contribute to an improved understanding of the role of structural and functional attributes in establishing biosimilarity and the mechanism of action of biological substances in general.

Abstract
The variation in the critical formulation variables during life-cycle of the drug product may result in undesirable changes in product performance. The current study aimed at evaluating the effects of formulation variables on the in vitro performance of carbopol-loaded testosterone gel. The formulation variables included concentrations of permeation enhancers, testosterone, ethanol, carbopol and sodium hydroxide. In vitro evaluation of the product performance included assessment of the rheological and morphological properties, kinetics of ethanol evaporation, and drug permeation through human cadaver skin. The results revealed that carbopol, sodium hydroxide and testosterone concentrations increased the viscosity of the gels significantly (p < 0.05). However, carbopol concentration was the only critical variable to affect the yield stress of the gel. The concentration of ethanol was critical to metamorphosis of the gel due to solvent evaporation upon application to skin with minor contributions from other formulation variables. The increase in concentration of isopropyl myristate or isopropyl palmitate to 5%, ethanol to 70%, and testosterone to 2%, enhanced the testosterone permeation across the skin by ten-folds. Synergistic effects of ethanol and permeation enhancers on testosterone permeation was observed. In conclusion, strict control over the critical formulation variables should be exercised during manufacturing to ensure desired product performance.

Abstract
Understanding the priorities of beef consumers is important for planning strategies to attract and maintain each customer. Using self-administered interviews with Spanish and Brazilian adults who regularly consume beef, we analyzed their purchasing behaviors in relation to their perceptions and priorities regarding beef quality that guide their choices. The current study identifies the influences of information (labeling and marketing) requirements, concerns about humane production systems, and the intrinsic characteristics of beef. To evaluate the data extracted from the interviews, the questions were grouped into four main factors. While extrinsic factors are the highest valued in both Spain and Brazil, those such as beef freshness and tenderness present inverse concerns between the two countries based on cultural dissimilarities. The data also reveals a clear symmetry among consumers who increasingly seek specific pre-purchase information and products with guaranteed superior quality. Despite other characteristics that differentiate developed and developing countries, the perceptions of quality among consumers in Spain and Brazil are decidedly similar.

Abstract
Non-destructive methods have been widely recognized for evaluating fruit quality traits of many horticultural crops and food processing industry. Destructive (analytical) test, and non-destructive evaluation of the quality traits were investigated and compared for 'Red Rose' tomato (Solanum lycopersicum L.) fruit grown under protected environment. Fresh tomato fruit at five distinctive maturity stages namely; breaker (BK), turning (TG), pink (PK), light-red (LR), and red (RD) were labeled and scanned using the handheld near infra-red (NIR) enhanced spectrometer at a wavelength range of 285-1200 nm. The labeled tomato samples were then measured analytically for flesh firmness, lycopene, β-carotene, total phenolic content (TPC) and total flavonoids content (TFC). The results revealed that quality traits could be estimated using NIR spectroscopy with a relatively high coefficient of determination (R2): 0.834 for total phenolic content, 0.864 for lycopene, 0.790 for total flavonoid content, 0.708 for β-carotene; and 0.679 for flesh firmness. The accumulation of Lyco and β-Car rapidly increased in tomatoes harvested between the TG and the LR maturity stages. Harvesting tomatoes at BK maturity stage resulted in significantly higher flesh firmness than harvesting at the later maturity stages. Tomato fruits had the lowest TPC and TFC contents at the earliest maturity stage (BK), while they had intermediate TPC and TFC levels at LR and RD maturity stages. NIR spectroscopic measurements of fruit firmness and lipophilic antioxidants in tomato fruit at various maturity stages were partially in accordance with those estimated by destructive (analytical) methods. Based on these findings, we recommend using non-destructive NIR spectroscopy as an effective tool for predicting tomato fruit quality during harvest stage and postharvest processing.

Abstract
Fruit seed is a by-product of fruit processing into juice and other products. Despite being treated as waste, fruit seed contains oil with health benefits comparable or even higher than the conventional seed oil from field crops. In addition to essential fatty acids, the fruit seed oil is a rich source of bioactive compounds such as tocopherols, carotenoids, flavonoids, phenolic acids and phytosterols, which have been implicated in the prevention of chronic and degenerative diseases such as cancer, diabetes and cardiovascular diseases. The emerging potential of fruit seed oil application in food and nutraceuticals has prompted researchers to study the effect of preharvest and processing factors on the seed oil quality with respect to nutritional qualities, antioxidant compounds and properties. Herein, the effect of cultivar, fruit-growing region, seeds pretreatment, seeds drying and seed oil extraction on tocopherols, polyphenols, phytosterols, carotenoids, fatty acids, antioxidant activity and oxidative stability of the fruit seed oil is critically discussed. Understanding the influence of these factors on seed oil bioactive phytochemicals, nutritional qualities and antioxidant properties is critical not only for genetically improving the oilseeds plants with desired characteristics, but also in seed oil processing and value addition. Therefore, preharvest and processing factors are essential considerations when determining the application of fruit seed oil.

Abstract
Biodiverse coffee systems are often understood to compromise conventional commercial outcomes due to reduced yield quantity and quality. The article seeks to improve the understanding of association between functional biodiversity and coffee quality definitions to clarify synergy between biodiversity and market value, subsequently answering the question, can or does biodiversity maintain or increase the market value of coffee. The understanding is expected to improve how conventional, specialty and sustainability coffee markets encourage biodiverse coffee farms and farming landscapes. Literature related to definitions of coffee quality, associations with farm and farming landscape biodiversity and subsequent associations with market value demonstrate current explanations, assessments and understandings of coffee quality definitions and associations between coffee quality definitions, market value and biodiversity as available in scholarly literature. Stakeholder definitions of coffee quality vary and are valued differently according to market type. Biodiversity in a coffee farm can associate directly with different coffee quality definitions with subsequent influence on conventional, sustainability and specialty market values. The associations include harvest quality, determined by yield quantity and quality, and other coffee quality indicators. Detail in understanding of these associations can easily improve, particularly between coffee quality definitions already valued by specialty and sustainability markets and biodiverse coffee farms, compared to monoculture farms.

Abstract
There are many intrinsic and extrinsic factors affecting the nutritional, organoleptic, microbial-enzymatic and physicochemical characteristics of food products. Some of these factors are commonly considered by food processors such as the temperature, water activity, pH, dissolved oxygen and chemical composition, while others are less considered such as the oxidoreduction potential (Eh). This latter factor is an intrinsic electrochemical parameter expressing the tendency of the substance/medium to give or receive electrons. Contrary to what is expected, the important role of Eh is not limited to inorganic chemistry, metallic chemistry, natural water, and wastewater treatment fields but it also covers many domains in biology such as metabolic engineering, enzymatic functions, food safety, and biotechnology. Unfortunately, although the critical roles of Eh in several key reactions occurred in biological media such as food and biotechnological products, its application or controlling is still uncommon or mis-considered by food processors. The lack of specific studies and reviews concerning the Eh and its influences on the quality parameters of products could be a reason for this lack of interest from the side of food processors. Recent studies reported the potential application of this parameter in novel food processing techniques such as reducing atmosphere drying (RAD) of food products and reducing atmosphere packaging (RAP) of fresh food products for preserving the quality attributes and extending the shelf-life of food products. This paper aims to help the technical and operational personnel working in food industry sectors as well as the scientific community to have an updated and a comprehensible review about the Eh parameter permitting its consideration for potential applications in food industries.

Abstract
The aim of this study was to use acidic electrolyzed water (AEW) to treat longan fruit and evaluate the effects of AEW treatment on storability, quality attributes and nutritive properties of longans during storage. The data indicated that, as compared to the control samples, AEW treatment could effectively reduce the respiration rate and pericarp cell membrane permeability, retard the occurrences of pericarp browning, pulp breakdown and fruit disease, keep a higher rate of commercially acceptable fruit. Additionally, AEW treatment could suppress the decrease of chromaticity values of L*, a* and b* of the fruit surface, keep higher amounts of pericarp carotenoid, chlorophyll, flavonoid and anthocyanin, maintain higher amounts of pulp total soluble solid (TSS), total soluble sugars, sucrose and vitamin C. These results demonstrated that AEW treatment at pH of 2.5, ACC of 80 mg/L could maintain higher quality attributes and nutritive properties, and display better storability of harvested longans.

Abstract
Immunoglobulin M (IgM) antibodies are considered as promising biopharmaceutical drugs in the future despite recombinant production is quite challenging as incomplete polymer formation or nucleic acid adherence can decrease the quality of the IgM preparation. Therefore, we defined densitometric and chromatographic methods as suitable tools to analyze the polymer distribution and the remaining nucleic acid content after initial IgM purification. Additionally, the quality of the glycosylation pattern is an important parameter for biological safety and efficacy.

Abstract
The aim of this study was to research the effect of yeast fermentation on the polyphenol content of Lycium ruthenicum (LR) to guide the production of bread with a lower digestibility. Liquid fermentation from 0 to 2 h significantly increased the phenolic, flavonoid and anthocyanin content of LR, while further liquid fermentation from 2 to 16 h had little additional effect. The addition of LR without prior liquid fermentation impaired the bread quality, while a prior liquid fermentation for at least 2 h improved the bread quality. The bread digestibility was decreased after adding LR, and it was further reduced with the extended liquid fermentation time. The results of this study indicate that adding LR with prior liquid fermentation to the dough during bread making could result in a higher quality and a lower digestibility.

Abstract
Effects of various concentrations of Kadozan (chitosan) treatment on storability and quality properties of harvested 'Fuyan' longans were investigated. Compared to the control samples, Kadozan treated-longans displayed lower fruit respiration rate, lower pericarp cell membrane permeability, pericarp browning index, pulp breakdown index, fruit disease index, and weight loss, but higher rate of commercially acceptable fruit, higher levels of pericarp chlorophyll, carotenoid, anthocyanin, flavonoid and total phenolics, higher amounts of pulp total soluble sugar, sucrose, total soluble solids, and vitamin C. These results revealed Kadozan treatment could increase storability and retain better quality of harvested longan fruit. Among different concentrations of Kadozan, the dilution of 1:500 (VKadozan: VKadozan + Water) showed the best results in storability and maintained the best quality of longans during storage. These findings demonstrated that Kadozan could be a facile and eco-friendly postharvest handling approach for increasing storability and lengthening shelf-life of harvested 'Fuyan' longan fruit.

Abstract
The present study investigates the effect of Acacia seed water extract (ASWE) at four levels (0, 50, 100, 150 mg/100 mL) in triplicate batch on the shelf-life and quality of chicken patties. Flavones, mainly (+)-catechin, were the predominant phenolic compounds in ASWE with high antioxidant activity. ASWE showed greater inhibition effects against gram-positive bacteria than gram-negative bacteria. ASWE incorporation had no significant effects on the chemical composition of chicken patties. The microbial load, and thiobarbituric acid reactive substances of chicken patties significantly decreased (P ≤ 0.05) and reached minimum values at 150 mg/100 mL but the pH decreased slightly. The cooking properties were significantly improved (P ≤ 0.05) at 150 mg/100 mL. Moreover, ASWE at high level (150 mg/100 mL) significantly (P ≤ 0.05) enhanced total phenolic content and free radical scavenging activity of chicken patties. The results showed that chicken patties with ASWE had better quality attributes compared to the unformulated. Shelf-life of chicken patties can therefore be prolonged for 15 days in refrigerated storage using ASWE especially at high concentration (150 mg/100 mL).

Abstract
This research evaluated the effects of different antioxidants on overall quality of beef patties from steers fed distillers grains. Crossbred steers (n = 24) were fed corn, 40% Dry distillers grains plus solubles, or 40% modified distillers grains plus solubles - Dry Matter basis). Patties were made from ground chuck of individual animals and 4 antioxidant treatments were evaluated (CONTROL - no antioxidant, 0.3% ROSEMARY, 0.25% ACEROLA, and 0.6% CITRUS). Diets minimally affected quality attributes. Patties treated with ROSEMARY were shown significant lighter in color than other treatments on day 6. Patties treated with CITRUS were the reddest on days 5 and 6 of display. ACEROLA and CITRUS provided better lipid stability during display when compared to CONTROL and ROSEMARY. Treatment CITRUS reduced APC growth by 2 log when compared to all other treatments (P < 0.01). Although patties treated with CITRUS had higher off-flavor intensity, no effect was observed for overall desirability. Patties treated with 0.6% of CITRUS provided optimal overall quality.

Abstract
Ultrasound is a novel technology that can be applied as a pretreatment for the convective drying in order to reduce its undeniable shortcomings. The objectives of the present study are to ascertain the influence of sonication time (10, 20, and 30 min) and sonication power (100 and 300 W) on the performance of drying potato slices with regard to the drying kinetics and energy efficiency as well as the final product quality. The results showed that the application of ultrasound pretreatments significantly increased the drying rate of potato slices during the initial period of the drying process. Furthermore, ANOVA showed that the decrease in the sonication time and power gave rise to a significant reduction in drying time, specific energy consumption (SEC), and shear strength. In addition, compared to the control (pure convective drying), ultrasound pretreatments reduced the drying time, SEC, and the shear strength of dried potato slices.

Abstract
This investigation was carried out to evaluate the effect of active and passive modified atmosphere packaging on quality and shelf life of yellow bell pepper fruits. Yellow bell pepper fruits were packaged in 150 gauge LDPE packages with oxygen absorbers for active modification and without oxygen absorber for passive modification of headspace and were stored at different temperatures i.e. 5, 10 and 15 °C and RH of 85 ± 5%. Headspace gas concentration within the packages was monitored regularly. The quality of packaged fruits was studied in terms of physiological loss in weight, firmness, total colour difference antioxidant capacity and total phenolic content. The actively modified packages attained steady state levels of 4.8% O2 and 7.1% CO2 on 4th day of storage as compared to passively modified packages in which steady state was not attained even at end of storage period of 12 days. The retention of quality attributes was observed to be higher in active packages than in passive packages. Moreover, the shelf life of actively packaged fruits was enhanced to 28 days as compared to 12 days for passively packaged fruits. The in-pack atmosphere attained in active packages hence proved beneficial in retarding the senescence thereby extending the shelf life.

Abstract
IgM antibodies are arousing considerable interest as biopharmaceuticals. Despite their immunotherapeutic potential, little is known about the impact of environmental conditions on product quantity and quality of these complex molecules. Process conditions influence the critical quality attributes (CQAs) of therapeutic proteins and thus are important parameters for biological safety and efficacy. Here, the results of a systematic study are presented that characterized the influence of temperature and pH on cell-specific productivity and IgM quality attributes. Biphasic temperature and pH shift experiments were performed as batch cultures in DASGIP® bioreactors under controlled conditions and defined by a specific design of experiment (DOE) approach. An internally-developed recombinant IgM producing CHO cell line was used. With respect to product quality, after an initial purification step efforts were focused on pentamer content, nucleic acid (NA) impurities and the glycosylation profile after an initial purification step. All quality attributes were evaluated by densitometric and chromatographic methods. The reduction of cultivation temperature severely reduced IgM titers, while pH variation had no impact. In contrast, IgM quality was not significantly influenced by bioprocessing parameters. Data revealed that an additional purification step is required to reduce the presence of NAs for in vivo applications. In conclusion, the results showed that for the chosen IgM model, IgM012_GL, variation in quality attributes is not caused by the environmental conditions of temperature and pH.

Abstract
The bacterium Escherichia coli is a major host for recombinant protein production of non-glycosylated products. Depending on the expression strategy, the recombinant protein can be located intracellularly, which often leads to protein aggregates inside of the cytoplasm, forming so the called inclusion bodies (IBs). When compared to other protein expression strategies, inclusion body formation allows high product titers and also the possibility of expressing proteins being toxic for the host. In the past years, the comprehension of inclusion bodies being only inactive protein aggregates changed, and the new term of non-classical inclusion bodies emerged. These inclusion bodies are believed to contain a reasonable amount of active protein within their structure. However, subsequent downstream processing, such as homogenisation of cells, centrifugation or solubilisation of IBs, is prone to variable process performance and is often known to result in low extraction yields. It is hypothesised that variations in IB quality attributes are responsible for those effects and that such attributes can be controlled by upstream process conditions. In this review, we address the impact of process design (process parameters) in the upstream on defined inclusion body quality attributes. The following topics are therefore addressed: (i) an overview of the range of inclusion body applications (including emerging technologies); (ii) analytical methods to determine quality attributes; and (iii) screws in process engineering to achieve the desired quality attributes for different inclusion body-based applications. Process parameters in the upstream can be used to trigger different quality attributes including protein activity, but are not exploited to a satisfying content yet. Design by quality approaches in the upstream are already considered for a multitude of existing processes. Further intensifying this approach may pave the industrial application for new IB-based products and improves IB processing, as discussed within this review.

Abstract
A two-step purification process for human basic fibroblast growth factor (FGF-2) from clarified E. coli homogenate has been developed in which the impurity level after the second step is below the limit of quantification. Endotoxin content is cleared to 0.02 EU/μg FGF-2 and the overall yield is 67%. The performance of the cation exchanger Carboxymethyl-Sepharose Fast Flow (CM-SFF) was compared to the affinity resin Heparin-SFF regarding the impurity profile and product quality in the elution peak. The CM-SFF eluate was further purified using hydrophobic interaction resin Toyopearl-Hexyl-650C. The relative amounts of target product, host cell proteins (HCPs), dsDNA, endotoxin, monomer content, and high molecular weight impurities differed along the elution peak depending on the applied method. The bioactive monomer (>99%) was obtained with a yield of 48% for CM-SFF and 68% for Heparin-SFF. A half-load reduction in CM-SFF increased the yield up to 67% without deterioration of the impurity content. Assuming a dose of 400 μg FGF-2, endotoxin was reduced to 188 EU/dose, dsDNA <10 ng/dose, and HCP <2 ppm/dose using the cation exchanger. In the pooled eluate fractions, dsDNA was removed 4-fold (291 ng/mL) and endotoxin 14-fold (0.47 EU/μg FGF-2) more efficiently by CM-SFF than by affinity chromatography. In contrast, HCP clearance was 3-fold (13 ppm) more efficient with Heparin-SFF than CM-SFF. In contrast to process monitoring by UV280nm or SDS-PAGE, this characterization is the basis for a Process Analytical Technology attempt when correlated with online monitored signals, as it enables knowledge-based pooling according to defined quality criteria.

Abstract
This study aimed to evaluate the antioxidant activity of Argel leaf water extract (ALWE) and its effect at different concentrations (0, 5, 10, and 20 mg/100 mL) on the antioxidant, antimicrobial, physicochemical, and sensory attributes of chicken meatballs during cold storage. ALWE contained substantial quantities of total phenolic content (TPC), anthocyanin, and exhibited high DPPH scavenging activity. ALWE incorporation in chicken meatballs had a varying effect on the chemical composition and sensory attributes of the product. However, ALWE incorporation at high concentration decreased the protein content of cooked meatballs and reduced fat content in both raw and cooked balls. Increased ALWE concentration in chicken meatballs lowered the pH, microbial load, and thiobarbituric acid reactive substances. Furthermore, ALWE raised the TPC and DPPH scavenging activity of chicken meatballs. Throughout the storage period, chicken meatballs formulated with ALWE showed better quality attributes than non-formulated chicken meatballs. In conclusion, ALWE can be employed as a functional ingredient for improved health benefits and shelf-life extension of chicken meatballs.

Abstract
The aim of this study was to investigate the effect of ultrasound assisted thermal processing also known as thermosonication (TS) on selected physicochemical and sensorial properties of beer. A typical Chinese lager beer was treated by TS (24kHz frequency and 2.7W/mL volumetric power) for 2min at 40, 50, and 60°C, respectively. The main quality attributes of the beer, such as ethanol content, original extract, pH, and bitterness, were scarcely affected by three TS treatments. However, a significant increase in color value was observed after TS treatment at 60°C during storage. The protein sensitivity and colloidal haze of three TS-treated beers increased slightly. The results also revealed that the development of both yeast and spoilage bacteria (including lactic acid bacteria and aerobic bacteria) was inhibited for 12months of storage for the TS-treated samples except for the TS-treated beer at 40°C. Additionally, the TS-treated beer at 60°C resulted in a higher thermal load relative to other two TS samples (at 40 and 50°C) based on the results of oxidative stability. TS treatment at 60°C also had a minor negative effect on the volatile profile by increasing staling compounds compared with other two TS treatments. These results obtained therefore may serve as a reference of the potential application of the ultrasound assisted thermal treatment for the beer processing.

Abstract
Thermal processing extends the shelf life of fruit and vegetables products by inactivating microorganisms and enzymes. The effect of a pasteurization (P) treatment, 90 ± 2 °C for 35 s, provided by continuous semi-industrial microwave (MW) under different conditions (high power/short time and low power/long time) or conventional pasteurization (CP) on orange-colored smoothies and their changes throughout 45 days of storage at 5 °C were investigated. Results indicated that vitamin C and antioxidant capacity (FRAP) in CP decreased dramatically in comparison with the unheated and MWP smoothies. On the contrary, all heating treatments increased the contents of total phenolic compounds and carotenoids. Based on the sensory quality and microbial counts, the shelf life of all those heated smoothies reached 45 days. No Listeria monocytogenes growth was found and all microbial counts were below the European legal limits (2007). MWP as compared to the CP method led to a greater reduction of mesophilic bacteria after 45 days at 5 °C (3.7 log cfu g-1 for CP and 1.6 log cfu g-1 for MWP). The highest power and the shortest time MWP treatments (3600 W for 93 s), resulted into better preservation of FRAP and vitamin C.

Abstract
UNLABELLED Specifications of drug products are quality standards that provide assurance that the drug is fit for its intended use. Establishment of specifications limits relies on data collected during the life cycle of a product, including those from preclinical and clinical trials, stability studies, and process validation, and often requires application of appropriate statistical methods. While quality attributes may be correlated, specifications are often determined without taking into account possible interdependence. Such practice may potentially result in specifications that are narrower than acceptable ranges of product performance. Through a case study, this paper discusses how this issue can be coped with effectively by using multivariate statistical modelling. LAY ABSTRACT Specifications of drug products are quality standards that provide assurance that the drug is fit for its intended use. Specifications are conventionally set up separately for each of the quality attributes of interest, without accounting for interdependence among the quality attributes. Such practice may potentially result in specifications that are narrower than acceptable ranges of product performance. Through a case study, this paper discusses how this issue can be coped with effectively by using statistical modelling.

Abstract
The combined effects of freezing and modified atmosphere packaging (MAP) (100% N2 and 50% N2+50% CO2) on some quality characteristics of Giant Red Shrimp (GRS) (Aristaeomorpha foliacea) was studied during 12-month storage. In particular, the quality characteristics determined proximal and gas compositions, melanosis scores, pH, total volatile basic-nitrogen (TVB-N), thiobarbituric acid (TBA) as well as free amino acid (FAA). In addition, the emergent data were compared to those subject to vacuum packaging as well as conventional preservative method of sulphite treatment (SUL). Most determined qualities exhibited quantitative differences with storage. By comparisons, while pH and TVB-N statistically varied between treatments (P<0.05) and TBA that ranged between ∼0.15 and 0.30 mg MDA/kg appeared least at end of storage for 100% N2 treated-group, the latter having decreased melanosis scores showed such treatments with high promise to keep the colour of GRS sample hence, potential replacement for SUL group. By comparisons also, while some individual FAA values showed increases especially at the 100% N2-treated group, the total FAAs statistically differed with storage (P<0.05). The combination of freezing and MAP treatments as preservative treatment method shows high promise to influence some quality characteristics of GRS samples of this study.

Abstract
The effect of low-pressure plasma on quality attributes of meat is an important aspect, which must be considered before application in food. The aim of this study was to determine the color, fatty acid composition, lipid oxidation expressed as thiobarbituric acid reactive substances and total antioxidant capacity of raw pork samples exposed to helium low-pressure plasma treatment (20 kPa) for 0, 2, 5, and 10 min during the storage period. The thiobarbituric acid reactive substance concentrations of all plasma-treated samples during storage were in the range from 0.26 to 0.61 mg malondialdehyde/kg. Exposure time caused significant changes only in total color difference, hue angle, and chroma after 10 min of treatment. Ferric reducing ability of plasma values of meat samples decreased from 1.93 to 1.40 mmol Trolox Eq/kg after 14 days of storage. The storage period significantly affected proportion of polyunsaturated fatty acids, with an increase about 3% after 14 days of refrigeration storage while the content of saturated fatty acids was at the same level. Helium low-pressure plasma does not induce oxidative processes. Application of this decontamination technique while maintaining product quality is possible in food industry.

Abstract
Pharmaceutical excipients containing volatile odor-active molecules can be used in pharmaceutical development to increase patients' compliance. However, capturing the molecular composition of these odor-active substances is challenging. Therefore, guidance for the analytical investigation of these excipients should be developed. Using a model flavor, lead molecules were chosen and a gas chromatographic method was validated according to pharmaceutical guidelines. Changes during storage as well as batch homogeneity and conformity were investigated. The knowledge gained could be used to understand molecular differences between batches caused by aging. A suitable attempt to capture the volatile molecular composition of flavoring substance was presented and the found results could be used for the determination and interpretation of quality attributes.

Abstract
Flavonoids (FGs) are a large group of polyphenolic compounds with low molecular weight, found in free and glycozidic forms in plants. Citrus fruits can be used as a food supplement containing hesperidin and flavonoids to prevent infections and boost the immune system in human body. The aim of this study was the investigation of the effect of clove oil and storage period on the amount of hesperidin and naringin component in orange peel (cv. Valencia). Four treatments including clove oil (1 %), wax, mixture of wax-clove oil, control and storage period were applied. Treated fruits were stored at 7 °C and 85 % relative humidity for 3 months and naringin, hesperidin, antioxidant activity, total pheenolic compounds, TSS, Vitamin C, fruits weight loss, pH, acidity and carbohydrates content were measured every 3 weeks. The amount of hesperidin and naringin was determined using high performance liquid chromatography at the detection wavelength of 285 nm. Antioxidant activity was measured using the 1, 1-diphenyl-2-picrylhydrazyl-hydrate (DPPH) free radical scavenging assay. Total phenolic compounds were measured using the Folin-Ciocalteu micro method. Results showed that naringin and hesperidin were decreased during storage. Different treatment only had significant effect on the amount of hesperidin while storage period affected both of narigin and hesperidin. Results of correlation study, indicated strong relation between antioxidant activity and amount of naringin and hesperidin during storage time. However, at the end of storage period, the amount of hesperidin and naringin were diminished independent of different covers. Probably anaerobic condition caused such reduction. Results showed that the amount of TSS, fruit hardness, weight loss, total sugar and fructose content were increased during storage period while total acidity, pH and glucose content showed descending trend during storage periods. In conclusion, hesperidin and naringin of peels can be used as suitable quality indexes indicating proper conditions for storage.

Abstract
The effect of salinity and silicon treatments on the marketable quality of four Marmande tomato varieties was investigated through conventional quality attributes and (1)H HRMAS NMR spectroscopy. Following variations in ripening through the content of GABA deduced from NMR was crucial for understanding the effects of environmental and nutritional factors. NMR data also lead to a new taste index, which increases from December to January. For Raf, Delizia and Conquista varieties, it was associated to ripening. In Tigre tomatoes the change, exclusively due to the decrease in sourness, does not affect the GABA content. The effect of the harvest day was more pronounced than treatments. However, increasing electrical conductivity seems an efficient alternative for improving fruit quality of Raf tomatoes harvest under non-optimal conditions. Silicon addition appears to reinforce the effect of light intensity on the quantity of photoassimilates available to the fruits without a clear effect on organoleptic quality.

Abstract
The present study was conducted to determine the effect of three different levels of sorbic acid (0.1 %, 0.2 % and 0.3 %) on the shelf life and storage quality of Kaladhi. Kaladhi was prepared from pasteurized buffalo milk standardized to 6 % fat and 9 % SNF with coagulation at 40 °C using 5 % lactic acid as a coagulant. Kaladhi prepared without sorbic acid served as control and was compared with the products treated with different levels of sorbic acid for a storage period of 35 days at ambient temperature. The results showed a significant (P < 0.05) effect of sorbic acid on most of the physicochemical parameters i.e. titratable acidity, free fatty acid content (% oleic acid) and thiobarbituric acid value which showed a decreasing trend with increasing concentration of sorbic acid. However, a non-significant (P > 0.05) effect of sorbic acid was observed on pH and proximate parameters of the product. Kaladhi treated with 0.3 % sorbic acid retained most desirable physicochemical and sensory properties throughout the storage period hence, was considered the best.

Abstract
Modified atmosphere packaging (MAP) is a dynamic system during which respiration and permeation occur simultaneously. Hence factors affecting both respiration and permeation were considered for designing a package. In the design of MA packages for guava (cv. Baruipur) a total of 13 variables were considered. The independent variables includes: weight of fruits, surface area of packaging film, free volume of the package, thickness of the film and permeabilities of film to O2 and CO2 gas. The fixed variables considered were: the surrounding gas composition and temperature, the respiration rates for O2 consumption and CO2 evolution, and the equilibrium gas compositions to be attained in the package so that the fruit's shelf-life is extended. Two types of MA packages, having package size of 19 cm × 19 cm for a fill weight of 1,000 ± 100 g were developed. Packages were designed to accommodate a fill weight range of 0.90-1.10 kg. Various package parameters were optimized to facilitate establishment of dynamic equilibrium at target levels of O2 and CO2 concentration in the package. The storage study of MA packages was performed at 10, 15, 20 and 25 °C temperatures. The performance of film packages was evaluated for their ability to establish equilibrium at target levels and to extend the shelf life of the packaged fruit. The MA packaging system increased the shelf life of guava by 128-200 % compared to the unpacked fruits at various storage temperatures with a quality comparable with the freshly harvested commodity.
