Abstract

The invention provides a method for preparing pea peptides with low bitterness, low enzyme consumption and high peptide yield, and belongs to the technical field of pea deep processing. In the present invention, the structure of pea protein is expanded through the pretreatment of high-pressure steam sterilization, which is more conducive to enzymolysis, and the bitterness value of the enzymolysis solution is greatly reduced through the compound enzymolysis of Alcalase protease and protease P, and the finally obtained peptide The powder has low bitterness, and the total enzyme amount is lower than that of the prior art. The preferred action pH value of protease P is similar to the preferred action pH value of Alcalase protease, which avoids the excessive increase of salt in the peptide powder, and the finally prepared peptide powder aqueous solution is close to neutral. The protein content of the pea peptide powder prepared by the method proposed by the invention is more than 90%, the peptide yield reaches 73%, and the generated free amino acid content is lower than 15%. The pea peptide powder prepared by the invention can be used for nutrition, health food and special medical formula food.

Description

technical field

[0001] The invention belongs to the technical field of pea deep processing, and in particular relates to a preparation method of pea peptide. Background technique

[0002] Pea protein is a newly emerging protein in recent years. It is low in price and hypoallergenic, and it is a good source of essential amino acids. At present, the utilization of pea in food in my country mainly focuses on making vermicelli from starch, while pea protein is mainly used as feed, with low added value. Pea peptide is the enzymatic hydrolysis product of pea protein, which is a direction of deep processing of pea protein. Studies have reported that pea peptides have various functions, such as anti-oxidation, anti-inflammation, lowering blood pressure, etc. In addition, the Chinese patent "A preparation method of pea peptide and its application in the field of whitening" (publication number: CN109055466A) discloses the application of pea peptide in the field of whitening (includi...
