Method for producing hydrolyzed wheat protein

Abstract

The invention discloses a method for producing hydrolyzed wheat proteins. The method is characterized by comprising the following steps of: preparing enzymatic hydrolysate, namely adding 1,000 parts of vital gluten in mass for three times according to the weight ratio of the vital gluten to water being 1 to 5-3, after hydrolysis is performed, raising the temperature of the enzymatic hydrolysate to 75-100 DEG C, keeping the temperature of the enzymatic hydrolysate for 3-10 minutes, performing enzyme deactivation on the enzymatic hydrolysate, cooling the enzymatic hydrolysate subjected to enzyme deactivation to 30-35 DEG C, after fermentation is finished, filtering fermented liquid, and finally drying the filtrate by spraying. The method has the advantages that by a multi-enzymolysis and microorganism fermentation combination method, a novel hydrolyzed wheat protein product is developed by fully combining characteristics of a protein structure of wheat gluten proteins, the cleavage sites of protease, biological conversion of microorganisms, animal nutrition absorption and the like, so that the taste and the flavor of the product are greatly improved; the utilization of enzyme preparations can be greatly reduced; the production cost is reduced; the production technology is simple and novel; the period is short; three industrial wastes are not produced; and the hydrolyzed wheat proteins are environmentally-friendly.

Description

technical field [0001] The invention relates to a production method of wheat hydrolyzed protein, in particular to a process for industrialized production of wheat hydrolyzed protein, a method for processing protein additives for feed, and belongs to the field of comprehensive development and application of deep processing of wheat. Background technique [0002] Gluten powder, also known as wheat gluten, is a by-product of the industrial production of wheat starch. It is a powdery product mainly made by washing, separating and drying. It is a cheap, high-quality, pure natural plant protein. Its protein content is as high as 72%~85%, containing 15 kinds of amino acids necessary for the human body, of which the glutamine content is as high as 30%, and the proline content is about 15%. It is rich in nutrients and has important physiologically active functions. The solubility is very poor, and when it is used as a feed protein source, its biological value and efficacy ratio are v...

AI Technical Summary

Problems solved by technology

However, because the enzymatic hydrolysis process is easy to produce by-products, the enzymatic hydrolysis process is difficult to control, resulting in incomplete hydrolysis, poor taste of hydrolyzed products, and difficult separation of target products

At the same time, the price of enzyme preparations is relatively high, causing the cost of enzymes to account for about 20% of the total cost. The high processing cost makes the price of wheat hydrolyzed protein high, and it is difficult to compete with other similar products in the market, and it is difficult to promote the market.
