The invention belongs to the technical field of microbial fermented beverages. In order to solve the problems of relatively few research reports of
anthocyanidin-containing pure microbial fermented beverages in the prior food and beverages and lack of
anthocyanidin-containing pure microbial fermented beverages which are also medicinal and edible
functional health care beverage products, the invention provides a compound microbial fermented beverage containing
anthocyanidin and a preparation method thereof. The compound microbial fermented beverage is prepared by mixing purple sweet potatoes, grapes, blueberries, strawberries, mulberries, haws and water in a certain proportion, performing
fermentation with a microbial
starter culture prepared from
lactobacillus plantarum,
lactobacillus rhamnosus,
lactobacillus acidophilus,
bifidobacterium breve and
saccharomyces cerevisiae and adding collagen polypeptides and
stachyose. The compound microbial fermented beverage provided by the inventioncan
resist oxidation, prevent
mutation,
resist allergies, prevent cardiovascular and cerebrovascular diseases, protect the liver, prevent
cancer, improve eyesight, eliminate harmful free radicals invivo, improve sleep, promote the proliferation of
beneficial bacteria in vivo and inhibit the
reproduction of harmful
bacteria and has a good auxiliary treating effect on various kinds of chronic diseases.
