Abstract
The present study aimed to enhance the survivability of the encapsulated biocomposites of Lactiplantibacillus plantarum AB6-25 and Saccharomyces boulardii T8-3C within the gastrointestinal system (GIS) and during storage period. AB6-25 and T8-3C were individually co-encapsulated using either lactobionic acid (LBA) in Na-alginate (ALG)/demineralized whey powder (DWP) or solely potential probiotics in ALG microcapsules. Free probiotic cells were utilized as the control group. Both microcapsules and free cells underwent freeze-drying. The encapsulation and freeze-drying efficiency of core materials were evaluated. The protective effect of encapsulation on the probiotics was examined under simulated GIS conditions and during storage at either 25 °C or 4 °C. Additionally, the microcapsules underwent analysis using fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscope (SEM). Encapsulation and freeze-drying processes were carried out efficiently in all groups (88.46 %-99.13 %). SEM revealed that the microcapsules possessed a spherical and homogeneous structure, with sizes ranging from 3 to 10 μm. ALG/DWP and LBA presence in the microcapsule structure was confirmed through FTIR, XRD analysis indicated the formation of a new composite. Over 180 days, all microcapsule groups stored at 4 °C maintained their therapeutic dosage viability. However, after four months, microcapsules stored at 25 °C exhibited a decline in yeast survivability below the therapeutic threshold. Experimental groups demonstrated better viability under simulated GIS conditions compared to the control. These findings suggest the potential use of microencapsulated probiotics as a food supplement and indicate that microcapsule groups containing AB6-25 and T8-3C stored at 4 °C can be preserved for six months.

Gedik O, Karahan AG. Physicochemical properties and survival assessment of potential probiotics in a novel dairy drink during storage. Food Sci Nutr 2023; 11:7803-7815. [PMID: 38107135 PMCID: PMC10724624 DOI: 10.1002/fsn3.3697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 09/01/2023] [Accepted: 09/05/2023] [Indexed: 12/19/2023] Open
Abstract
A novel fermented dairy drink utilizing microbial strains displaying potential probiotic attributes was formulated. The study constituted several experimental cohorts, including Lactiplantibacillus plantarum AB6-25, isolated from a human stool sample; Lacticaseibacillus casei K2, sourced from a koumiss sample; Lacticaseibacillus rhamnosus 3B7, derived from a traditional yogurt sample; and identical lactic acid bacteria (LAB) in combination with yeast (Saccharomyces boulardii T8-3C from chicken feces) strains. Two distinct iterations of probiotic-fermented dairy drinks were generated by introducing subcultured microorganism cultures: LAB strains at a concentration of 1% each (designated as combination A) and a blend of LAB strains at 1% each along with T8-3C at 0.5% (designated as combination B) into both whole and semi-skimmed milk matrices. The fermentation process persisted until the pH reached 4.6 under constant conditions of 37 ± 1°C. Subsequently, the samples were held at 4 ± 1°C for 15 days. The groups' physicochemical, microbiological, and sensory characteristics were determined on days 1, 8, and 15 of storage, and the protein profile was determined. Standardized regression analysis and principal component analysis evaluated the results. Fat content affected the changes in dry matter. pH decreased in all samples during storage, particularly in the yeast group. The microorganism group positively affected syneresis, whereas fat content and the interaction of fat content and the microorganism group had a negative effect. The most critical factor in the decrease in syneresis was the increase in fat content. LAB and yeasts maintained their probiotic effects during storage, with a viability level of approximately 109 and 108 cfu/mL, respectively.

Abstract
The aim of this systematic review and meta-analysis was to determine which variables affect the viability of lactic acid bacteria (LAB) added to different types of refrigerated foods during the first 28 days. Scopus, ScienceDirect, PubMed and Cochrane Central Register of Reviews databases were searched from 1997 to April 2022. A total of 278 studies, which showed randomized and controlled experiments published in peer reviewed journals, were included. The viability of LAB in different moments during the storage process was synthesized as mean point estimate (MPE) via random-effects meta-analyses and the effect of multiple factors on the LAB´s viability was evaluated by multiple meta-regression. The meta-analysis showed that the decrease in LAB viability will be more abrupt the greater the initial dose. The physical structure of food may influence bacterial viability. Fruit was the type of product that most quickly lost viability. Co-culture of two or more species did not affect viability. Preservation methods had an unfavorable effect and prebiotics had a beneficial effect on bacterial viability. Viability was genus dependent. The data obtained in this study provide an overview of the factors to be taken into account for the design of new foods.

Abstract
The increasing health awareness of consumers has made a shift towards vegan and non-dairy prebiotics counterparts. Non-dairy prebiotics when fortified with vegan products have interesting properties and widely found its applications in food industry. The chief vegan products that have prebiotics added include water-soluble plant-based extracts (fermented beverages, frozen desserts), cereals (bread, cookies), and fruits (juices & jelly, ready to eat fruits). The main prebiotic components utilized are inulin, oligofructose, polydextrose, fructooligosaccharides, and xylooligosaccharides. Prebiotics' formulations, type and food matrix affect food products, host health, and technological attributes. Prebiotics from non-dairy sources have a variety of physiological effects that help to prevent and treat chronic metabolic diseases. This review focuses on mechanistic insight on non-dairy prebiotics affecting human health, how nutrigenomics is related to prebiotics development, and role of gene-microbes' interactions. The review will provide industries and researchers with important information about prebiotics, mechanism of non-dairy prebiotics and microbe interaction as well as prebiotic based vegan products.

Abstract
Blueberries have received great attention due to the health effects of their bioactive compounds, such as antioxidant, antitumor, and anti-obesity properties. Probiotics also have these health-promoting benefits. However, these biological activities may be affected by the processs of gastrointestinal digestion, which decreases their functionality. This study aimed to use a more convenient method to improve the blueberries’ antioxidant activity and protective effects on probiotic cells by fermentation with whey protein, and to explore the possible mechanisms underlying these effects. This result showed that the total phenolic content, anthocyanin content, reducing power, DPPH radical scavenging capacity, and probiotic cells’ survival in a blueberry juice and whey protein fermentation system were enhanced in a model of in vitro gastrointestinal digestion. The bioactive compounds in blueberry juice interacted with whey protein, as shown through FTIR. The stability of phenolic compounds was enhanced, and the release of functional compounds in the mixture fermentation system was delayed through CLSM. Interactions between bioactive compounds in blueberries, whey protein, and bacterial surface proteins, glycoproteins or polysaccharides during fermentation were studied by SDS-PAGE. Thus, the stability of bioactive activities in the mixed system after fermentation was strengthened by the interaction. The mixed fermentation system has promising potential for improving antioxidant activity and protecting probiotic cells.

Abstract
Shiga-toxin-producing Escherichia coli O157:H7 is a well-known water- and food-borne zoonotic pathogen that can cause gastroenteritis in humans. It threatens the health of millions of people each year; several outbreaks of E. coli O157:H7 infections have been linked to the consumption of contaminated plant foods (e.g., lettuce, spinach, tomato, and fresh fruits) and beef-based products. To control E. coli O157:H7 in foods, several physical (e.g., irradiation, pasteurization, pulsed electric field, and high-pressure processing) and chemical (e.g., using peroxyacetic acid; chlorine dioxide; sodium hypochlorite; and organic acids, such as acetic, lactic, and citric) methods have been widely used. Although the methods are quite effective, they are not applicable to all foods and carry intrinsic disadvantages (alteration of sensory properties, toxicity, etc.). Therefore, the development of safe and effective alternative methods has gained increased attention recently. Biocontrol agents, including bacteriophages, probiotics, antagonistic bacteria, plant-derived natural compounds, bacteriocins, endolysins, and enzymes, are rapidly emerging as effective, selective, relatively safe for human consumption, and environmentally friendly alternatives. This paper summarizes advances in the application of biocontrol agents for E. coli O157:H7 control in foods.

The Effect of Lactiplantibacillus plantarum BX62 Alone or in Combination with Chitosan on the Qualitative Characteristics of Fresh-Cut Apples during Cold Storage. Microorganisms 2021; 9:microorganisms9112404. [PMID: 34835529 PMCID: PMC8618497 DOI: 10.3390/microorganisms9112404] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Revised: 11/17/2021] [Accepted: 11/20/2021] [Indexed: 12/11/2022] Open
Abstract
In order to explore whether beneficial lactic acid bacteria (LAB) could prolong the shelf life and improve the quality of fresh-cut apples, Lactiplantibacillus plantarum BX62, which was isolated from traditional fermented yak yogurt, and chitosan (CT), were applied to fresh-cut apples, subsequently stored at 4 °C. On days 0, 2, 4, 6, and 8, apple slices were taken for physicochemical, microbiological analysis, and sensory evaluation. The results showed that apple slices coated with L. plantarum BX62 (8 log CFU/mL) presented lower weight loss and browning rate, higher DPPH scavenging capacity, and achieved more effective inhibition of polyphenol oxidase (PPO) and peroxidase (POD) activities compared to the control samples. The application of CT alone or in combination with L. plantarum BX62 resulted in a significant reduction in aerobic mesophilic bacteria (AMB), aerobic psychrophilic bacterial (APB), yeast and molds (YAMs) counts (2.31 log CFU/g for AMB, 2.55 for APB, and 1.58 for YAMs). In addition, L. plantarum BX62 coated apples showed acceptable sensory properties in terms of color, flavor, taste, texture, and overall visual quality during 8 d of storage. On this basis, L. plantarum BX62 could be used as an excellent bio-preservative to extend the shelf life and improve the quality of fresh-cut apples.
