Microbiological Dimensions Symbiotic Culture of Bacteria and Yeast (SCOBY) and Functional Properties of Kombucha Tea Fermented Drink

Kombucha is a fermented tea beverage whose global popularity is driven by its distinctive flavor and purported health benefits. This review provides a comprehensive analysis of its production, microbial ecosystem, and nutritional profile, distinguishing between consumer perception and scientific evidence for its functional properties. We examine the critical challenges in production and safety, including microbial contamination, SCOBY variability, and controlling acetic acid and ethanol levels. The analysis further addresses the regulatory landscape governing alcohol content and health claims, as well as emerging market trends. Finally, we identify key future directions, underscoring the necessity for technological innovation, robust clinical validation, and enhanced quality control to align the kombucha industry with evolving consumer and regulatory standards.
