Shinga MH, Fawole OA. Opuntia ficus indica mucilage coatings regulate cell wall softening enzymes and delay the ripening of banana fruit stored at retail conditions. Int J Biol Macromol 2023; 245:125550. [PMID: 37356689 DOI: 10.1016/j.ijbiomac.2023.125550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 06/03/2023] [Accepted: 06/22/2023] [Indexed: 06/27/2023]
Abstract
Rapid ripening and softening due to cell wall polysaccharide degradation and disassembly pose major challenges in extending fruit storability. This study aimed to examine the efficacy of Opuntia ficus indica mucilage (OFIM) edible coating in minimizing softening in bananas under retail conditions. Mucilage was extracted from freshly harvested prickly pear cladodes and dried into a powder. Phenolic compounds in OFIM powder were quantified using liquid chromatography-mass spectrometry (LC-MS). OFIM concentrations (1, 2 and 3 % (w/v)) were prepared, and their physicochemical properties were examined. The prepared coatings were applied to harvested banana fruit by dipping and stored at room temperature for 12 days. During the experiment, several parameters were measured, including fruit weight loss, total soluble solids (TSS), titratable acidity (TA), peel color, pulp firmness, ethylene production, respiration rate, ion leakage, malondialdehyde (MDA) content, total chlorophyll and carotenoids, chlorophyll-degrading enzymes, protopectin content and water-soluble pectin (WSP) and softening-related enzymes in the peel. Results showed that mucilage treatments effectively delayed cell wall and chlorophyll degradation, as well as carotenoid accumulation, thus inhibiting ripening-associated processes compared to control fruit. OFIM-treated fruit exhibited significantly higher firmness, chlorophyll content, and TA, lower TSS content, ethylene production, respiration rate, MDA concentration, ion leakage and protopectin content than uncoated fruit. This suggests that OFIM edible coating has the potential to maintain quality and extend the shelf life of bananas by suppressing softening enzymes during storage.

Abstract
The storage life of pomegranate fruit (Punica granatum L.) is limited by decay, chilling injury, weight loss, and husk scald. In particular, chilling injury (CI) limits pomegranate long-term storage at chilling temperatures. CI manifests as skin browning that expands randomly with surface spots, albedo brown discoloration, and changes in aril colors from red to brown discoloration during handling or storage (6-8 weeks) at <5-7 °C. Since CI symptoms affect external and internal appearance, it significantly reduces pomegranate fruit marketability. Several postharvest treatments have been proposed to prevent CI, including atmospheric modifications (MA), heat treatments (HT), coatings, use of polyamines (PAs), salicylic acid (SA), jasmonates (JA), melatonin and glycine betaine (GB), among others. There is no complete understanding of the etiology and biochemistry of CI, however, a hypothetical model proposed herein indicates that oxidative stress plays a key role, which alters cell membrane functionality and integrity and alters protein/enzyme biosynthesis associated with chilling injury symptoms. This review discusses the hypothesized mechanism of CI based on recent research, its association to postharvest treatments, and their possible targets. It also indicates that the proposed mode of action model can be used to combine treatments in a hurdle synergistic or additive approach or as the basis for novel technological developments.

Relationship among Sugars, Organic Acids, Mineral Composition, and Chilling Injury Sensitivity on Six Pomegranate Cultivars Stored at 2 °C. Foods 2023; 12:foods12071364. [PMID: 37048185 PMCID: PMC10093234 DOI: 10.3390/foods12071364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 03/17/2023] [Accepted: 03/20/2023] [Indexed: 04/14/2023] Open
Abstract
Pomegranate is a sensitive fruit to chilling injury (CI) during storage at temperatures below 7 °C. However, sensitivity of pomegranate to CI is dependent on cultivar and exposure times to low temperatures. In this work, the sensitivity to CI of six pomegranate cultivars (Punica granatum L.) 'Wonderful', 'Kingdom', 'Bigful', 'Acco', 'Purple Queen', and 'Mollar de Elche', was evaluated after 30 d at 2 °C plus 2 d at 20 °C. Among cultivars, there was a great variability in the sensitivity to the appearance of CI symptoms. 'Kingdom' cultivar was the most CI sensitive and 'Mollar de Elche' cultivar was the least sensitive cultivar. CI symptoms were greater in the internal part of the skin than in the external part, although no correlation was found between ion leakage (IL) and CI severity after cold storage. However, both, external and internal CI index were correlated with the IL at harvest, with Pearson correlation of 0.63 and 0.80, respectively. In addition, this variability to CI among cultivars could also be due to composition and tissue structures in arils and peel. The solute content of the arils (anthocyanins, sugars, and organic acids, in particular citric acid), showed high correlations with CI sensitivity, with Pearson correlations (r) of 0.56 for total soluble solids, 0.87 for total acidity, 0.94 for anthocyanins, -0.94 for oxalic acid, 0.87 for citric acid, 0.62 for tartaric acid, -0.91 for malic acid, 0.8 for sucrose, and 0.71 for glucose, which can leak to the inner surface of the peel causing browning reactions. In addition, the high peel Ca/K ratio could play an important role on increasing fruit tolerance to CI, since it was negatively correlated with the internal and external CI indexes.

Abstract
Cold-stored 'Nanguo' pears are susceptible to peel browning during subsequent shelf life. In this study, 'Nanguo' pears were cold-stored for different periods to elucidate the metabolism of phenylpropanoid accompanying browning. Changes in phenolics and flavonoids and the crucial enzyme activity and related gene expression involved in the phenylpropanoid pathway were monitored. It was found that the fruit that underwent long-term storage showed peel browning symptoms prior to softening, and the symptom got worse with increasing shelf life. Meanwhile, the accumulation of reactive oxygen species (ROS) and the decrease of ROS scavenging ability were noted. The content of phenolics and flavonoids and the activity and expression of shikimate dehydrogenase (SKDH), phenylalanine ammonia-lyase (PAL), cinnamate-4-hydroxylase (C4H), and 4-coumarate-CoA ligase (4CL) involved in the phenylpropanoid pathway decreased with prolonged storage. Correlation analysis revealed that browning was positively correlated with ROS accumulation, and the content of phenolics and flavonoids directly affected ROS scavenging ability. In addition, the decrease in phenolics and flavonoids might be owing to the reduced activity of SKDH, PAL, and 4CL and the down-regulated expression of PuPAL and Pu4CL. Collectively, this study indicated that the metabolism of phenylpropanoid is associated with the browning response induced by low-temperature stress.

Abstract
Chitosan edible coating (Ch; 2% w/v) enriched with 2% of 0.1 mg/L Bidens pilosa (Ch+B), Lippia javanica (Ch+L), Syzygium cordatum (Ch+S), or Ximenia caffra (Ch+X) was applied as a composite edible coating in alleviating shrivel and maintaining the quality of purple passion fruit (Passiflora edulis var. Ester). Treated fruit were dipped for 3 min in the coating solution, and control fruit were dipped in distilled water. The fruit were stored at 8±2 °C and 90±5% relative humidity (RH) for 32 d. Sampling was done every 8 d plus 3 d (20±2 °C and 50±5% RH) to simulate retail conditions. Efficacy of medicinal plant extracts in the chitosan matrix varied; lower ethylene production (82.42 µL C2H4/kg h) was seen in fruit coated with Ch+S, and the lowest respiration rate (75 mL CO2/kg h) was observed in fruit coated with Ch+B. The control fruit showed the highest ethylene production (84.90 µL C2H4/kg h) and respiration rate (117.98 mL CO2/kg h). Fruit coated with Ch+B had the lowest weight loss (41.67%), higher juice content (60.13%) and BrimA (3.31), while the control fruit had the highest weight loss (88.03%), lowest juice content (21.90%), and BrimA (2.49). Shrivel incidence was lowest (23.70%) on fruit coated with Ch+L and highest (83.30%) on the control fruit. Fruit coated with Ch+X had the lowest electrolyte leakage (71.40%), while the control fruit had the highest (91.97%). Fruit coated with chitosan alone performed better than the control fruit but did not exceed the quality of composite chitosan coated fruit. Based on the principal component analysis, it can be concluded that passion fruit coated with Ch+B was more effective in alleviating shrivel incidence, better maintained the quality of passion fruit during storage, and shows potential for commercial applications.

Abstract
This study evaluated the efficacy of chitosan (CH) functionalized with 24-epibrassinolide (EBR) coating in terms of preserving the postharvest quality of late-harvested pomegranate (cv. Wonderful) fruit. Late-harvested pomegranate fruit were immersed for 3 min in different surface treatment solutions—CH 1.5% (w/v), CH + 2 µM EBR, CH + 5 µM EBR, CH + 10 µM EBR and CH + 15 µM EBR—and distilled water was used as a control treatment. The fruit were air-dried and subjected to long storage duration at 5 °C with 85 ± 5 RH for 12 weeks. At 4-week sampling intervals, a batch of fruits was placed at 21 ± 2 °C and 65–70% RH for a further 3 d period to simulate retail conditions before measurements were taken. Fruit physiological responses, physico-chemical properties, phytochemical contents, antioxidant capacity and physiological disorders were monitored during storage. The results showed that the CH-EBR composite edible coatings significantly (p < 0.05) delayed degradative processes due to senescence. The CH-EBR treatments delayed colour, texture and total soluble solids (TSS) degradation and reduced weight loss, respiration, electrolyte leakage and spoilage compared to the control and CH treatment. The treatment effect was more noticeable on fruit treated with CH + 10 µM EBR, which exhibited lower weight loss (18.19%), respiration rate (7.72 mL CO2 kg−1 h−1), electrolyte leakage (27.54%) and decay (12.5%), and maintained higher texture (10.8 N) and TSS (17.67 °Brix) compared to the untreated fruit with respective values of 24.32%, 18.06 mL CO2 kg−1 h−1, 43.15%, 37.5%, 8.32 N and 17.03 °Brix. This was largely attributed to the significantly higher antioxidant content, including the ascorbic acid content, total phenol content, total anthocyanin content and DPPH (radical scavenging activity), of the coated fruit compared to the control fruit. Therefore, CH + 10 µM EBR treatment is recommended as a postharvest management strategy to improve the quality preservation of late-harvested pomegranate fruit during storage.

Abstract
Lemon trees (Citrus limon (L.) Burm. F) were treated monthly with oxalic acid (OA) at 0.1, 0.5, and 1 mM from initial fruit growth on the tree until harvest in2019. The experiment was repeated in 2020, with the application of OA 1 mM (according to the best results of 2019). In both years, fruit from OA-treated trees and the controls were stored for 35 days at 10 °C. Results showed that all treatments reduced weight loss (WL) and maintained higher firmness, total soluble solids (TSS), and total acidity (TA) than in the controls. Meanwhile, colour (hue angle) did not show significant differences. The activity of antioxidant enzymes, catalase (CAT), ascorbate peroxidase (APX), and peroxidase (POD) in the flavedo of the fruit from the OA-treated trees was higher than in the controls at harvest and after 35 days of storage. Similarly, the total phenolic content (TPC) in the flavedo and juice of the fruit from the OA-treated trees were higher than in the controls. The increase in the activity of the antioxidant enzymes and TPC started with the first preharvest OA treatment and were maintained during fruit development on the tree until harvest. Preharvest OA treatments enhanced the antioxidant system of the lemon fruits, reducing the postharvest incidence of decay. Thus, OA could be a useful tool to increase the quality and functional properties of lemon fruits.

Abstract
In order to exploit the functional properties of fresh beetroot all year round, maintaining the health-benefiting compounds is the key factor. Thirty-six beetroot genotypes were evaluated regarding their content of total dry matter, total phenolic compounds, betalain, nitrate, and total soluble sugars directly after harvest and after cold storage periods of one and four months. Samples were collected from two field experiments, which were conducted under organic conditions in Southwestern Germany in 2017 and 2018. The outcome of this study revealed a significant influence of genotype (p < 0.05) on all measured compounds. Furthermore, significant impacts were shown for storage period on total dry matter content, nitrate, and total phenolic compounds. The medians of nitrate content based on the genotypes studied within the experiment ranged between 4179 ± 1267-20,489 ± 2988 mg kg-1 DW (dry weight), and that for the total phenolic compounds varied between 201.45 ± 13.13 mg GAE 100 g-1 DW and 612.39 ± 40.58 mg GAE 100 g-1 DW (milligrams of gallic acid equivalents per 100 g of dry weight). According to the significant influence of the interactions of storage period and genotype on total soluble sugars and betalain, the decrease or increase in the content of the assessed compounds during the cold storage noted to be genotype-specific. Therefore, to benefit beetroots with retained quality for an extended time after harvest, selection of the suitable genotype based on the intended final use is recommended.

Abstract
Postharvest life of table grapes is usually shortened by berry softening, berry drop, stem browning, fungal decay. Salicylic acid reduces fruit respiration and ethylene biosynthesis, during storage of fruits. Similarly, application of oxalic acid is a secure and hopeful postharvest handling technology for keeping quality and prolonging storage life of fruit. To study the effect of Salicylic acid and oxalic acid in enhancing the quality and extending the shelf life of grape, the present investigation was conducted. The grape berries were treated with Oxalic acid (OA) (1, 2, 3, 4, and 5 mM) and Salicylic acid (SA) (0.5, 1, 1.5 and 2 mM). The treatments were compared within 16th days at an interval of 4 days. Among the treatments, SA (2 mM) showed superiority in different quality attributing characters like physiological loss in weight (PLW), berry firmness, rachis browning, berry appearance, fungal decay, berry shattering, TSS, ascorbic acid, titratable acidity, total sugars, reducing sugars, TSS: acid ratio, taste, overall acceptability and shelf life. Hence, SA (2 mM) can be used as an effective strategy for maintaining quality of table grapes.

Abstract
Choice of drying methods significantly impacts the nutritive and non-nutritive compounds in fruits and vegetables. Phytochemicals such as total phenolics and total flavonoids are non-nutritive bioactive compounds and are found in plants which are of important value due to their antioxidant properties in minimizing the oxidation reaction. However, drying and storage conditions and duration significantly affect these important quality attributes. There is currently no review article on the impact of the drying and storage conditions on these quality attributes. Therefore, the aim of this review paper is to investigate the impact of drying methods on these important phytochemicals and their antioxidant activity on dried products during the storage period. Different drying methods cause desirable and undesirable changes to dried products both physically and chemically. It is found that during the drying process at various temperature ranges from 40 to 80 °C, chemical changes occurs which affects the phenolic and the flavonoid content of dried products to increase or decrease. The increase in antioxidant activity after drying is also due to oxidized polyphenols and Maillard reaction products. This results to changes in the antioxidant potential of the dried food product and its impact on the shelf life.

[PMID: 32713083 DOI: 10.1111/jfbc.13393] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 06/17/2020] [Accepted: 07/03/2020] [Indexed: 11/28/2022]
Abstract
Pomegranate is a subtropical fruit that affects its cold storage. To ameliorate chilling injury, fruits were treated with malic acid (50 and 100 mM MA) and oxalic acid (5 and 10 mM OA), and then, coated with 2% chitosan (CH) and stored at low temperature (2°C) for 4 months. Treatments significantly delayed the development of browning signs and reduced malondialdehyde and hydrogen peroxide of arils as compared to control. CH+ 5 mM OA resulted in the highest catalase activity in arils during storage. Anthocyanin, ascorbic acid, total phenolic compound, and antioxidant activity of arils were higher in CH+ 5 mM OA and CH+ 50 mM MA-treated fruit. Also, the minimum PPO and POD activity of arils was found in CH+ 5 mM OA. Overall, CH edible coating following organic acids treatment, and especially 5 mM OA and 50 mM MA are beneficial treatments for preserving the quality of pomegranate fruit during storage. PRACTICAL APPLICATIONS: Pomegranate fruit waste is high due to chilling sensitivity during cold storage. Coating fruit with 2% chitosan (CH) alone and with malic acid (50 and 100 mM MA) and oxalic acid (5 and 10 mM OA) could ameliorate chilling injury. Treatments reduce the development of browning signs. Overall, CH edible coating combined with 5 mM OA and 50 mM MA were the most effective treatments for ameliorating the chilling injury of pomegranate fruit.

Abstract
Pomegranate is a subtropical and chilling sensitive fruit. In this study, the effects of malic acid (50 and 100 mM) and oxalic acid (5 and 10 mM) on quality properties of pomegranate during cold storage (2 ℃) were investigated. The lowest weight loss was observed in fruit treated with 50 mM malic acid. Malic acid had positive effects on color parameters (L*, a*, and b*) of pomegranate at low temperature. Organic acid treatments reduced chilling injury, malondialdehyde, and hydrogen peroxide and increased catalase activity. The lowest activity of polyphenol oxidase and peroxidase was observed in 5 mM oxalic acid-treated fruit. On the other hand, fruit treated with 50 mM malic acid showed the maximum ascorbic acid and citric acid content. The most antioxidant activity was found in fruit treated with 5 mM oxalic acid and 50 mM malic acid. Also, all treatments except 10 mM oxalic acid and 100 mM malic acid resulted in higher titratable acidity than control fruit. Overall, 50 mM malic acid and 5 mM oxalic acid were the most effective for preserving the quality of pomegranate fruit at low temperature.

Abstract
Purslane, a fleshy herbaceous plant, plays a pivotal role in various preventive and therapeutic purposes. To date, no report has documented the consequence of salt stress on metabolite accumulation in purslane. Herein, we proposed an insight into the metabolic and physiological traits of purslane under saline stress environments. The gas chromatography-mass spectrometry analysis was used to scrutinize the metabolic profiling of leaves and roots of two purslane genotypes, Tall Green (TG) and Shandong Wild (SD), under the control and saline exposures. Results revealed that the morphological and physiological traits of leaves and roots of both the tested Portulaca oleracea cultivars in response to salt stress (100 mM and 200 mM) were dramatically changed. Similarly, significant differences were found in the metabolite profiles among samples under salinity stress treatments as compared with the control. Thorough metabolic pathway analysis, 132 different metabolites in response to 28 days of particular salt stress treatments were recognized and quantified in roots and leaves of purslane, including 35 organic acids, 26 amino acids, 20 sugars, 14 sugar alcohols, 20 amines, 13 lipids and sterols, and 4 other acids. In conclusion, this study can be useful for future molecular experiments as a reference to select gene expression levels for the functional characterization of purslane.

Abstract
The objective of this study was to investigate the shelf life of arils and the changes in their biochemical compounds in nineteen Iranian pomegranate cultivars during storage. Fruits were harvested when commercially mature and the arils were removed, packaged and stored at 5 ± 1 °C, at 85-90% relative humidity in a cold room. Samples of the stored arils were examined for biochemical features in temporal checkpoints throughout a storage period that lasted for 35 days. By using the onset of decay as an index, the shelf life of arils varied among cultivars, ranging from 7 days to approximately 21 days. Considering the quality attributes of ready-to-eat arils at the beginning of the experiment, substantial variations were observed among the cultivars with regard to their titratable acidity (0.50-8.47%), total soluble solids (13-18.66 °Brix), DPPH radical scavenging activity (63-87.44%), Gallic-acid-equivalent (2.64-6.95 mg/ml) and ascorbic acid (12.21-75.09 mg/l). In general, the decay of arils gradually increased during storage, but several cultivars-which exhibited a very slow process of decay-contained the highest content of titratable acidity, Gallic-acid-equivalent and total soluble solids (since the signs of decay appeared on around the twenty-first day of storage). In addition, titratable acidity increased slightly by the end of storage, whereas the ascorbic acid content, total soluble solids and Gallic-acid-equivalent were cultivar-dependent and did not show consistent patterns of change during storage.

Abstract
BACKGROUND Plums are much appreciated by consumers as fresh fruit but have a limited storage life. Since reactive oxygen species (ROS) are associated with fruit ripening, an increase in ROS scavenging antioxidant systems could lead to a delay in postharvest plum ripening and in maintaining fruit quality after long cold storage. RESULTS Results showed that crop yield (kg per tree) and fruit weight were enhanced by preharvest oxalic acid (OA) treatment of plum cultivars ('Black Splendor' and 'Royal Rosa'), although the on-tree ripening process was delayed. In addition, the ripening process during cold storage was delayed in plums from OA-treated tress, manifested by lower firmness and acidity losses and reduced ethylene production, as compared with fruits from control trees. Antioxidant compounds (phenolics, anthocyanins and carotenoids) and the activity of antioxidant enzymes were higher in plums from OA-treated trees than in controls, at harvest and during 50 days of cold storage. CONCLUSION OA preharvest treatment could be a useful tool to maintain plum quality properties during long-term storage, by delaying the postharvest ripening process through a delay in ethylene production, with an additional effect on increasing bioactive compounds with health beneficial effects. © 2018 Society of Chemical Industry.

Abstract
Delicate fruit of strawberry is susceptible to high temperature stress and fungal infection. An extensive spray program is usually adapted to secure yield and fruit quality which sometimes pose a serious threat to consumer health. However, development of eco-friendly, economical and safer strategies has always been in focus of R&D sector. In this study, field-grown strawberry plants cv. Chandler were sprayed with 1, 2 or 3 mM oxalic acid at flowering stage. Interestingly, foliar application of oxalic acid in low doses (1 mM and 2 mM) had more growth-promoting effect on strawberries whereas foliar application of 3 mM oxalic acid either negatively affected or remained ineffective. Low-dose applications of oxalic acid resulted in enhanced nitrogen (1.5-fold), phosphorus (2.5-fold) and potassium (1.75-fold) levels in leaf petioles. Increase in primary macronutrients was also correlated well with enhancement in plant growth indicators including dry biomass (1.5-fold), leaf area (1.7-fold), specific leaf area (2.8-fold) and leaf area ratio (2.6-fold), root weight ratio (1.9-fold), root-to-shoot ratio (1.4-fold). Only, leaf chlorophyll and fresh fruit weight were negatively impacted by oxalic acid. In addition to increase in number of fruits per plant, oxalic acid also improved sensory properties of strawberry fruits mainly due to increase in sugar: acid ratio (1.6-fold), ascorbic acid contents (1.2-fold) and non-reducing sugars (2-fold). Overall, foliar application of 1 mM oxalic acid favoured vegetative growth and enhanced yield and fruit quality of strawberry cv. Chandler.

Abstract
Combined effects of controlled atmosphere and different postharvest treatment (salicylic acid, oxalic acid and putrescine) on bioactive compounds and quality of pomegranate cv. Hicaznar were investigated. Pomegranates were harvested at commercial harvest stage and transported immediately to postharvest physiology laboratory. Fruit were divided into four groups. 1 Control: Dipped into distilled water + 0.01% Tween-20 solution for 10 min. 2 Oxalic acid (OA): Dipped into 6 mM OA + Tween-20 solution for 10 min. 3 Salicylic acid (SA): Dipped into 2 mM SA + Tween-20 solution for 10 min. 4 Putrescine (PUT): Dipped into 2 mM PUT + Tween-20 solution for 10 min. After treatments, pomegranates were stored at 6 °C and 90 ± 5% relative humidity for 6 months in controlled atmosphere (5% O2 + 15% CO2). Weight loss, color, total soluble solids content, titretable acidity (TA), total phenolic content, vitamin C, antioxidant activity and sugar content (glucose and fructose) were determined at 0th, 2th, 4th and 6th month of cold storage. Generally, weight losses were minimized by treatments, especially PUT, compared to control. The level of ascorbic acid significantly tended to decrease throughout the storage in all treatments. Treated pomegranate exhibited higher titratable acidity, total phenolic contents and antioxidant activity compared to control samples. However, PUT was the best among all treatments. The results suggest that SA, OA and PUT have the potential to extend the storage life of pomegranate by delaying quality loss and maintaining some bioactive compound and antioxidant activity.

Abstract
γ-Aminobutyric acid is a non-protein amino acid involved in various metabolic processes. The objectives of this study were to examine whether increased GABA could improve heat tolerance in cool-season creeping bentgrass through physiological analysis, and to determine major metabolic pathways regulated by GABA through metabolic profiling. Plants were pretreated with 0.5 mM GABA or water before exposed to non-stressed condition (21/19 °C) or heat stress (35/30 °C) in controlled growth chambers for 35 d. The growth and physiological analysis demonstrated that exogenous GABA application significantly improved heat tolerance of creeping bentgrass. Metabolic profiling found that exogenous application of GABA led to increases in accumulations of amino acids (glutamic acid, aspartic acid, alanine, threonine, serine, and valine), organic acids (aconitic acid, malic acid, succinic acid, oxalic acid, and threonic acid), sugars (sucrose, fructose, glucose, galactose, and maltose), and sugar alcohols (mannitol and myo-inositol). These findings suggest that GABA-induced heat tolerance in creeping bentgrass could involve the enhancement of photosynthesis and ascorbate-glutathione cycle, the maintenance of osmotic adjustment, and the increase in GABA shunt. The increased GABA shunt could be the supply of intermediates to feed the tricarboxylic acid cycle of respiration metabolism during a long-term heat stress, thereby maintaining metabolic homeostasis.

Abstract
The effects of oxalic acid on the development of chilling injury (CI), energy metabolism and lycopene metabolism in tomato fruit (Solanum lycopersicum L.) were investigated. Mature green tomatoes were dipped in 10mmoll(-1) oxalic acid (OA) solution for 10min at 25°C. Tomatoes were subsequently stored at 4±0.5°C for 20days before being transferred to 25°C for 12days. Oxalic acid treatment apparently alleviated CI development and membrane damage; maintained higher levels of ATP and ADP; increased activities of succinic dehydrogenase (SDH), Ca(2+)-adenosine triphosphatase (Ca(2+)-ATPase) and H(+)-adenosine triphosphatase (H(+)-ATPase); and elevated lycopene accumulation associated with the upregulation of PSY1 and ZDS expression in tomatoes during a period at room temperature following exposure to chilling stress. Thus, oxalic acid treatment benefited the control of CI and the maintenance of fruit quality in tomatoes stored for long periods (approximately 32days).

Abstract
Pomegranate is a subtropical and tropical fruit of great importance from a health point of view. Despite increasing consumer awareness of the health benefits of pomegranate, consumption of the fruit is still limited owing to poor postharvest handling, storage recommendations, short shelf life and quality deterioration during transportation, storage and marketing. The occurrence of physiological disorders such as husk scald, splitting and chilling injury is another challenge reducing marketability and consumer acceptance. Recently, notable work on postharvest biology and technology has been done. Pomegranate is highly sensitive to low-oxygen (<5 kPa) atmospheres, chilling injury and decay. One of the major problems associated with pomegranate fruit is excessive weight loss, which may result in hardening of the husk and browning of the rind and arils. To reduce chilling injury incidence and to extend storability and marketing of pomegranates, good results were obtained with polyamine, heat, salicylic acid, methyl jasmonate or methyl salicylate treatments prior to cold storage. This article reviews the maturity indices, changes during maturation and ripening, postharvest physiology and technology of pomegranate fruit as well as the various postharvest treatments for maintaining fruit quality.

Abstract
Peaches (Prunus persica cv. Yanhong) were fumigated with carbon monoxide (CO) at 0, 0.5, 5, 10, and 20 μmol/L for 2 hours. The result showed that low concentration CO (0.5–10 μmol/L) might delay the decrease of firmness and titrable acid content, restrain the increase of decay incidence, and postpone the variation of soluble solids content, but treating peaches with high concentration CO (20 μmol/L) demonstrated adverse effects. Further research exhibited that exogenous CO could induce the phenylalnine ammonialyase activity, maintain nutrient contents such as Vitamin C, total flavonoid, and polyphenol, and enhance antioxidant activity according to reducing power and 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl radical scavenging activity. Treating peaches with appropriate concentration CO was beneficial to the quality, nutrients, and antioxidant activity of postharvest peaches during storage time. Therefore, CO fumigation might probably become a novel method to preserve postharvest peach and other fruits in the future.

Abstract
Trees of 'Sweet Heart' and 'Sweet Late' sweet cherry cultivars (Prunus avium L.) were treated with oxalic acid (OA) at 0.5, 1.0, and 2.0 mM at 98, 112, and 126 days after full blossom. Results showed that all treatments increased fruit size at harvest, manifested by higher fruit volume and weight in cherries from treated trees than from controls, the higher effect being found with 2.0 mM OA (18 and 30% higher weight for 'Sweet Heart' and 'Sweet Late', respectively). Other quality parameters, such as color and firmness, were also increased by OA treatments, although no significant differences were found in total soluble solids or total acidity, showing that OA treatments did not affect the on-tree ripening process of sweet cherry. However, the increases in total anthocyanins, total phenolics, and antioxidant activity associated with the ripening process were higher in treated than in control cherries, leading to fruit with high bioactive compounds and antioxidant potential at commercial harvest (≅45% more anthocyanins and ≅20% more total phenolics). In addition, individual anthocyanins, flavonols, and chlorogenic acid derivatives were also increased by OA treatment. Thus, OA preharvest treatments could be an efficient and natural way to increase the quality and functional properties of sweet cherries.

Oxalic acid alleviates chilling injury in peach fruit by regulating energy metabolism and fatty acid contents. Food Chem 2014; 161:87-93.

Abstract
The effects of postharvest oxalic acid (OA) treatment on chilling injury, energy metabolism and membrane fatty acid content in 'Baifeng' peach fruit stored at 0°C were investigated. Internal browning was significantly reduced by OA treatment in peaches. OA treatment markedly inhibited the increase of ion leakage and the accumulation of malondialdehyde. Meanwhile, OA significantly increased the contents of adenosine triphosphate and energy charge in peach fruit. Enzyme activities of energy metabolism including H(+)-adenosine triphosphatase, Ca(2+)-adenosine triphosphatase, succinic dehydrogenase and cytochrome C oxidase were markedly enhanced by OA treatment. The ratio of unsaturated/saturated fatty acid in OA-treated fruit was significantly higher than that in control fruit. These results suggest that the alleviation in chilling injury by OA may be due to enhanced enzyme activities related to energy metabolism and higher levels of energy status and unsaturated/saturated fatty acid ratio.

Abstract
Sweet cherry cultivars ('Cristalina' and 'Prime Giant') harvested at commercial ripening stage were treated with salicylic acid (SA), acetylsalicylic acid (ASA) or oxalic acid (OA) at 1 mM and then stored for 20 days under cold temperature. Results showed that all treatments delayed the postharvest ripening process, manifested by lower acidity, color changes and firmness losses, and maintained quality attributes for longer periods than controls. In addition, total phenolics, anthocyanins and antioxidant activity increased in untreated fruit during the first 10 days of storage and then decreased, while in fruits of all treatments, these parameters increased continuously during storage without significant differences among treatments. Thus, postharvest treatments with natural compounds, such as SA, ASA or OA, could be innovative tools to extend the storability of sweet cherry with higher content of bioactive compounds and antioxidant activity as compared with control fruits.
