A multi-strain composite multi-stage fermented Ziziphus jujuba Mill. health beverage and a preparation method thereof

Abstract

The present invention discloses a multi-strain composite multi-stage fermented Ziziphus jujuba Mill health beverage and a preparation method thereof, belonging to the technical field of health foods. It includes the following steps: (1) mixing Ziziphus jujuba Mills with water for homogenization, adding pectinase for enzymatic hydrolysis, and inactivating the enzyme after completion of the enzymatic hydrolysis to obtain an enzymatic hydrolysate; (2) adding Saccharomyces boulardii to the enzymatic hydrolysate for sealed fermentation; (3) inoculating Acetobacter for secondary fermentation; (4) further inoculating a composite bacterial liquid of Lactobacillus plantarum and Bifidobacterium animalis for a third fermentation; (5) subjecting the final fermentation liquid to organic membrane filtration columns to remove impurities, adjusting sugar content and acidity, and filling for storage.
