Kombucha is an ancient, fermented beverage that has gained increasing popularity worldwide due to its potential health benefits. Its origins trace back China, from where it spread across Asia and Europe before reaching the modern global market. The fermentation of kombucha mediated by a Symbiotic Culture Bacteria Yeasts (SCOBY), comprising yeasts, acetic acid bacteria, lactic bacteria. microbial consortium plays crucial role in production organic acids bioactive metabolites, shaping sensory characteristics beverage. Given growing interest as functional beverage, this study aims explore historical background, process, microbiological composition, including key bacteria their interactions. Additionally, we describe effects kombucha, particularly antimicrobial antioxidant activity, probiotic strains associated with safety considerations while also addressing risks consumption. Although several studies suggested may have antioxidants, antimicrobial, properties, well contribute gut microbiota regulation immune system support, there significant variability composition especially artisanal preparations. This poses challenges standardizing ensuring consistent safety. risk contamination further underscores importance adhering strict sanitary standards. To scientifically validate benefits guarantee safe consumption, research larger sample sizes robust methodologies essential. findings will deeper understanding properties provide scientific support for beneficial applications.

Given the environmental, ethical, and food security challenges posed by conventional agriculture animal husbandry, transition towards sustainable systems is essential. Plant-based foods, especially those enhanced fermentation, present a viable solution. Fermentation reduces ecological footprint, aligns with ethical standards, enhances plant-based proteins' nutritional value sensory attributes, offering credible alternative to products. This paper explores fermentation's transformative role in developing meats, dairy, protein alternatives, emphasizing its benefits, including improved gut health through probiotics prebiotics. It also addresses such as producing undesirable by-products, potential risks, increased costs associated fermentation. Detailed examinations of specific fermentation processes—alcoholic, lactic acid, acetic propionic butyric acid—and their impact on enhancing value, digestibility, flavor foods are presented. Case studies from pioneering companies demonstrate technologies' practical applications market potential. Lastly, discusses future opportunities scaling up processes incorporating advanced biotechnological techniques further enhance sustainability outcomes.
