Method for producing yeast extract with high protein content and product

Abstract

The invention relates to a method for producing yeast extract, which comprises the following step: (a) autolysis, namely performing autolysis under the condition of keeping the pH value of a liquid yeast between weak acidity and neutrality, and adjusting the pH value for at least one time in the autolysis process to perform the autolysis under the condition of different pH values. The invention also relates to the yeast extract obtained by the method. In the autolysis process, yeast entogenous enzyme is effectively activated by adjusting a pH value, and conversion rate of products is improved. The yeast extract produced by the method has obviously improved contents of protein and amino-acid nitrogen.

Description

technical field

[0001] The invention relates to a production method of yeast extract, in particular to a production method and product of yeast extract with high protein content. Background technique

[0002] Yeast extract is obtained by degrading the protein in yeast cells into amino acids and polypeptides, and degrading nucleic acids into nucleotides, and extracting them from yeast cells together with other active ingredients, such as B vitamins, glutathione, trace elements, etc. After extraction, the prepared human body can directly absorb and utilize, a concentrate of soluble nutrients and flavor substances. In recent years, with the improvement of people's living standards, people have put forward new requirements for the content of diet, and various foods are increasingly developing in the direction of natural, convenient, delicious and multifunctional. Seasonings or chemical seasonings are turned to natural compound seasonings with higher taste; meanwhile, the season...
