Problems solved by technology

[0004] However, when the common hydrolyzed wheat protein is prepared, the type of enzyme added is relatively single, which makes the reaction speed slower, resulting in a lower yield in the preparation process of the hydrolyzed wheat protein

Abstract

The invention discloses a preparation method of hydrolyzed wheat protein. The preparation method comprises the following steps: weighing 10-20 parts of papain and 5-10 parts of thermophilic protease, and adding the papain and the thermophilic protease into a reaction kettle in the step S2; adding trypsin into the mixed solution prepared in the step S4, heating and stirring the solution, and when the temperature is increased to 40 DEG C, the mixed solution continues to be subjected to a hydrolysis reaction; when the pH is adjusted to 8.5, adding 1.5-3 parts of a compound enzyme preparation into the system, starting hydrolysis, adding trypsin, papain, thermophilic protease and the compound enzyme preparation, so that different enzymes can fully react with wheat gluten protein powder in the hydrolysis process of wheat protein, therefore, the hydrolysis speed of the wheat protein in the hydrolysis process is increased, the reaction is more thorough, the yield of the hydrolyzed wheat protein is increased, and more economic benefits are brought to manufacturers.

Description

technical field [0001] The invention belongs to the technical field of hydrolyzed protein production, in particular to a preparation method of hydrolyzed wheat protein. Background technique [0002] Wheat contains about 13% protein, mainly composed of albumin, globulin, gliadin and glutenin, while wheat gluten mainly contains gliadin and glutenin, collectively called storage protein (accounting for wheat protein dry basis Due to the extensibility of gliadin, glutenin has elasticity and can form a network structure with water, so it has excellent viscoelasticity, extensibility, water absorption, liposuction emulsification, film forming properties and light alcohol Distinctive physical characteristics such as aroma or slightly grainy taste. [0003] The main amino acids of hydrolyzed wheat protein are gliadin and glutenin, which are rich in cystine. It has moisturizing, anti-oxidation, soft and refined skin, and has special emollient ingredients, which can improve wrinkles. ...
