Special Issue Information

Dear Colleagues,

The first volume of this Special Issue (https://www.mdpi.com/journal/foods/special_issues/EVH32406BV) was a success and gained the attention and interest of many scholars. I would like to take the opportunity here to thank them for their contributions and support. As this Special Issue continues to attract the attention of scholars and play a pivotal role in this area of research, we are looking forward to the launch of this second edition.

Natural fruit and vegetable beverages have increasingly attracted consumer attention due to their nutritional and health benefits. Lactic acid bacteria (LAB), renowned for their probiotic and fermentation capabilities, have already found widespread applications in dairy and wine production. The application of LAB on other fruit and vegetable beverages has emerged as a research hotspot, given their substantial impact on the nutrient composition of beverages such as organic acids, polyphenols, carotenoids, amino acids, and polysaccharides, as well as their influence on sensory and quality characteristics. Therefore, we are pleased to introduce the second edition of this Special Issue, "Advances in Utilizing Lactic Acid Bacteria for Enhanced Quality and Nutrition in Fruit and Vegetable Beverages", which will focus on the applications of LAB in further improving the quality and nutritional profile of fruit and vegetable beverages.

We welcome contributions on a wide range of topics, including, but not limited to, strain selection, fermentation process optimization, innovative technology, metabolic mechanisms, and nutritional and functional evaluations. These contributions will both advance the scientific understanding and the practical applications of LAB-fermented fruit and vegetable beverages.

The wine ecosystem constitutes a highly selective ecological niche characterized by low pH, high ethanol levels, sulfur dioxide, polyphenols, and nutrient limitation. During malolactic fermentation, this environment becomes dominated by specialized lactic acid bacteria (LAB), particularly Lactiplantibacillus plantarum and Oenococcus oeni, whose persistence under such stressors suggests the presence of adaptive traits relevant to probiotic development. In this study, twenty-three LAB isolates obtained from the spontaneous wine ecosystem were systematically evaluated through a multi-stage screening strategy. Primary single-factor assays revealed pronounced inter- and intraspecies variability in tolerance to acid, lysozyme, and bile salts. As a result, all O. oeni isolates and eight L. plantarum strains were excluded from further consideration. The four selected L. plantarum isolates (M-1, SY-2, XJA2, and XJ14) were subsequently subjected to simulated gastrointestinal challenges. Strains M-1 and XJ14 maintained high viability across both gastric and intestinal phases. In contrast, SY-2 and XJA2 exhibited pronounced gastric sensitivity but demonstrated strong survival in the intestinal phase. Functional characterization further distinguished the isolates: M-1 and XJ14 displayed balanced probiotic profiles, whereas XJA2 exhibited exceptional auto-aggregation and efficient metabolic capacity, suggesting specific colonization potential despite its gastric vulnerability. Comprehensive safety assessments confirmed the absence of hemolytic activity, biogenic amine production, and acquired antibiotic resistance in the tested isolates. Collectively, these findings identify M-1 and XJ14 as promising candidates for direct probiotic application, and XJA2 as a promising functional strain for encapsulation-based delivery. This study highlights the wine ecosystem as a valuable reservoir for novel probiotic development. Full article
