Effect Of Milk and Water Kefir Granules in Sugar Solution

This study investigates the effect of milk and water kefir granules on sugar solution, focusing on their fermentation characteristics and potential applications in the production of functional beverages. Kefir grains, which are symbiotic cultures of bacteria and yeasts (SCOBY), were introduced into sugar solutions to evaluate their fermentation processes, including pH change, sugar consumption, and the production of lactic acid, alcohol, and other metabolites. The two types of kefir granules—milk and water—were compared to determine any differences in fermentation rate, microbial diversity, and the final composition of the fermented solution. Results indicate that both milk and water kefir grains were capable of fermenting sugar solutions, with milk kefir demonstrating a more complex microbial profile and a greater production of lactic acid, while water kefir showed higher ethanol content and a faster fermentation rate. The findings suggest that both kefir types can be used for producing probiotic-rich beverages, with the milk kefir being more suited for dairy-based functional drinks, while water kefir may offer a suitable alternative for non-dairy and vegan applications. The study also explores the broader implications of kefir fermentation in enhancing the nutritional and health-promoting properties of sugar-based substrates.
