Abstract

The invention provides soyprotein peptide beer and a preparation method thereof. The preparation method comprises the following steps of: firstly, hydrolyzing mixed gelatinization swort of rice and bean pulp by using bacillus subtilis CICC10063 to prepare a clear mash rich in soyprotein peptide; fermenting a mixed mash of the soyprotein peptide clear mash and saccharified wort by adopting beer yeast CICC31362; and after post-fermentation, filtering by using a plate frame to prepare the soyprotein peptide beer.

Description

(1) Technical field [0001] The invention relates to a beer rich in soybean protein peptides and a preparation method thereof. (2) Background technology [0002] Beer is a well-known alcoholic beverage, and it is also one of the most widely consumed alcoholic beverages in the world. The beer we drink every day is mainly a low-alcohol beverage produced by fermenting malt and hops. Its production It can be roughly divided into three main processes: malting, beer brewing, and beer filling. In the past half century, the world beer industry has developed particularly rapidly, with production doubling successively and per capita consumption also rising. As far as the overall situation of the world beer industry is concerned, the industry has entered a mature stage of steady development. However, the variety of beer in our country is single, which is in obvious contrast with the beer varieties refurbished in beer powerhouses such as the United States and Germany. In recent years,...
