Embodiment 1

[0022] A method for enzymatically producing pea peptides, the steps are as follows:

[0023] Weigh 1kg of commercially available pea protein powder (where crude protein>61wt%, moisture<10wt%, ash<3wt%) after passing through a 40-mesh sieve, add 7kg of distilled water, 50g of 95wt% ethanol and 10g of anhydrous sodium sulfite, and stir After uniformity, heat up to 90°C and reflux for 5 hours, and filter while hot after the reaction; then cool the filtrate to 50°C, adjust the pH to 7-8 with 0.1M food-grade flaky sodium hydroxide solution, then add 20g of alkaline protease, Stir and enzymolyze at 50°C for 6 hours. During the enzymolysis process, use the above-mentioned 0.1M sodium hydroxide solution to keep the pH value of the reaction system at 7-8; The sodium hydroxide solution of M keeps the pH value of the reaction system at 7-8; then the temperature is raised to 90° C., and the enzyme is kept for 20 minutes to kill the enzyme; then the enzymolysis solution is filtered to obta...

Abstract

The invention discloses a method for producing a pea peptide through an enzyme method, comprising the following steps of: blending screened and edulcorated pea protein powder used as main raw materials with water, ethanol and sodium sulfite to react for 3-5 hours; filtering and cooling to 50-60 DEG C; then sequentially adding two proleases for enzymolysis; modifying; inactivating enzyme; decoloring; separating a membrane; and carrying out spray drying on obtained filter liquor to obtain the pea peptide. The method acquires the pea peptide through a biological double enzyme method, has the advantages of simple production process, short production period, low cost, easy and convenient operation, moderate reaction condition, environmental protection and high safety performance and can be widely used in the fields of drugs, health care products, and the like.

Description

technical field [0001] The method of the invention relates to the technical field of deep processing of pea protein powder, in particular to a method for enzymatically producing pea peptide, which uses pea protein powder as a raw material, uses biological enzymes to enzymolyze the pea protein powder, and then utilizes biological enzyme modification technology to produce pea peptides. A method for extracting pea peptides by modifying protein peptides. Background technique [0002] Pea grains contain 15.5%-39.7% protein, about 2% fat, and are rich in vitamins B1, B2 and niacin. Pea protein resources in my country are extensive and cheap. Pea peptides can be obtained by hydrolyzing pea protein, and the pH value is neutral. Studies have shown that pea peptide contains 8 amino acids that the human body cannot synthesize by itself, and their ratio is close to the recommended mode of FAO / WHO. [0003] However, since these amino acids basically exist in proteins in the form of agg...
