Mixed strain fermented beer beverage and its preparation method

Abstract

The invention discloses a mixed strain fermented beer beverage. During the preparation process, at the beginning of the fermentation step, three different strains are inoculated into 13 degree P wort according to the weight ratio of 1:1:1, wherein the three different strains are beer yeast, gluconacetobacter and Lactobacillus casei, and the inoculation amount accounts for 10% of the total amount of the wort. According to the mixed strain fermented beer beverage, beer yeast is adopted for fermentation by a common beer fermentation process route. The main flavor formed is beer flavor. The beer beverage contains alcohol and CO2. Gluconacetobacter generates a physiological activator gluconic acid. Lactobacillus casei generates a physiological activator L-lactic acid. In addition, the finished product beer contains live beer yeast, gluconacetobacter and Lactobacillus casei which are easily absorbed by human intestinal tract and help improve intestinal flora quality. The mixed strain fermented beer beverage is a novel beer beverage which has nutrition and health functions as well as unique mouthfeel and local flavor.

Description

technical field

[0001] The invention relates to a functional health-care beer and a preparation method thereof, belonging to the technical field of beer brewing technology, in particular to a mixed strain fermented beer beverage and a preparation method thereof. Background technique

[0002] Typically, brewing beer involves converting starch into a sugary liquid called "wort," which is then fermented by yeast into alcohol-containing beer. Wort has been used in beer brewing for thousands of years. Beer brewing mainly includes three processes: saccharification, fermentation, and aging after storage. Beer brewing mainly includes the following five processes:

[0003] 1) Raw material crushing: the malt and rice are respectively crushed by a grinder to a crushing degree suitable for saccharification operation.

[0004] 2) Saccharification: Mix the crushed malt and starchy auxiliary materials in the gelatinization pot and the mashing pot respectively with warm water, and adjust...
