Mung bean protein peptide preparation method

Abstract

The invention discloses a mung bean protein peptide preparation method, which belongs to the technical field of protein peptide processing, and comprises the following steps: (1) conditioning protein emulsion; (2) conducting primary hydrolysis; (3) conducting protease hydrolysis; (4) conducting centrifugal separation; (5) carrying out high-speed separation on a liquid phase, and carrying out secondary hydrolysis on a solid phase; (6) carrying out protease inactivation; (7) carrying out centrifugal separation; (8) carrying out high-speed separation on the liquid phase, and carrying out third decomposition on the solid phase; (9) carrying out protease inactivation; (10) performing centrifugal separation, removing by-products from the solid phase, and performing high-speed separation on the liquid phase; (11) performing membrane separation; (12) performing membrane concentration; and (13) drying to obtain a mung bean protein peptide finished product. According to the method, the peptide conversion rate of the mung bean protein is increased through fractional hydrolysis, ultrafiltration membrane separation and nanofiltration membrane concentration, the peptide content of a product is stabilized, the proportion of small molecule peptides less than 500d is increased, the peptide activity is improved, and the evaporation energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of protein peptide processing, and in particular relates to a preparation method of mung bean protein peptide. Background technique [0002] At present, small molecular active peptides have not been widely sold in the market, and mung bean peptides are even rarer. In the production process of mung bean protein peptides, there are mainly problems such as low protein conversion rate, poor stability of peptide content, unsatisfactory peptide activity, and high energy consumption. Contents of the invention [0003] The object of the present invention is to provide a method for preparing mung bean protein peptide in view of the existing problems. [0004] The present invention is achieved through the following technical solutions: [0005] A method for preparing mung bean protein peptide, comprising the steps of: [0006] (1) Condition the protein milk, adjust the pH value to 7.2, kill bacteria, and fully de...
