This invention discloses a method for preparing a mulberry-monk fruit fermented beverage, belonging to the field of microbial
fermentation technology. The method includes
raw material processing, alcoholic
fermentation,
acetic acid fermentation, and blending steps: Monk fruit is extracted using a combination of juice extraction and hot water countercurrent extraction; the extract is kept warm to improve
clarity and inactivate enzymes; using mulberry juice and monk
fruit juice as substrates,
fruit wine yeast is inoculated for anaerobic fermentation; then, monk
fruit juice and edible
alcohol culture are added to adjust the
alcohol content, followed by aerobic fermentation with *
Acetobacter acetosporum* and
acetic acid bacteria; finally, the fermented juice,
glycoside-containing monk
fruit juice, mulberry concentrate, and
erythritol are blended to prepare the beverage. This invention fully utilizes mulberry and monk fruit resources, retains active ingredients such as polyphenols, anthocyanins, and polysaccharides, and produces a low-
calorie, flavorful, and safe product suitable for industrial production, possessing both nutritional and
health benefits.
