Preparation method of health-care instantly-dissolved protein powder

Abstract

The invention belongs to the technical field of food processing, and particularly relates to a preparation method of health-care instantly-dissolved protein powder. The method comprises the steps that food-grade rice protein powder and food-grade corn protein powder are weighed and mixed, a glucose solution is added into the mixture and stirred to be uniform, sterilization is conducted, bacillus subtilis is inoculated for fermentation, boiling and cooling are conducted after fermentation is completed, and sterilized fermentation liquor is obtained; mung bean sprouts and the sterilized fermentation liquor are mixed and sent into a colloid mill, a mixed slurry is obtained, the mixed slurry is hydrolyzed and filtered, filtrate is obtained and subjected to concentrating and spray-drying, and the finished product is obtained. The health-care instantly-dissolved protein powder prepared through the method is rich in amino acid and small peptide, contains a large number of functional ingredients of gamma-aminobutyric acid and the like, is easy to absorb and has multiple effects of improving the organism immunity, lowering blood pressure, strengthening the brain and the like.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of health-care instant protein powder. Background technique [0002] Protein mainly comes from animal food and plant food. Animal protein has a complete range of essential amino acids and a reasonable ratio, so it is easier to digest, absorb and utilize than ordinary plant protein, and its nutritional value is relatively higher. However, due to the lack of certain essential amino acids in plant protein, the degree of plant protein being absorbed and utilized by the human body will be poor. There are two ways to improve the nutritional efficacy of plant protein, first, [0003] Mix different types of vegetable protein, such as grain protein and soy protein, the essential amino acids contained in the two can complement each other, and can reach or approach the level of animal protein, which can improve the utilization of protein Second, af...
