Method for preparing double protein polypeptide soya bean milk powder solid drink

Abstract

The invention relates to a preparation method of double-protein polypeptide soya-bean milk powder solid beverage, which comprises the following steps: (1) soybean is used to prepare soya-bean milk; (2) the enzyme in partial soybean protein of the soya-bean milk is treated with enzymolysis by prolease into soybean polypeptide; (3) the enzyme is killed to obtain polypeptide soya-bean milk; (4) the following raw materials are first prepared: the polypeptide soya-bean milk, whole milk powder, maltose syrup, white sugar, soybean fiber, edible soybean oil, soybean oligosaccharide, edible calcium carbonate, vitamin A and vitamin D; and then the whole milk powder, the maltose syrup, the white sugar, the soybean fiber, the edible soybean oil, the soybean oligosaccharide, the edible calcium carbonate, the vitamin A and the vitamin D are added into the polypeptide soya-bean milk and mixed evenly, to obtain mixed liquid; (5) the mixed liquid receives spray drying treatment, and the double-protein polypeptide soya-bean milk powder solid beverage is obtained. The double-protein polypeptide soya-bean milk powder solid beverage prepared by the invention has vegetable protein, animal protein, the soybean polypeptide, high nutrition value and is better for the health of human body.

Description

technical field [0001] The invention relates to the preparation of soybean milk powder, in particular to a method for preparing a double-protein polypeptide soybean milk powder solid beverage. Background technique [0002] Protein is an important nutrient for the human body. Soybean is rich in resources, cheap and nutritious, especially high in protein content. Soybean protein contains eight essential amino acids and does not contain cholesterol. Therefore, soybean protein is a suitable source of protein for the human body, and has the advantages of high quality and low price. [0003] However, at present, instant foods such as soybean milk and soybean milk powder made of soybeans only contain vegetable protein and do not contain animal protein, and their nutritional structure is relatively simple, so they cannot provide comprehensive nutrition for the human body. [0004] In addition, the traditional view is that protein is mainly absorbed by the human body in the form of ...

Problems solved by technology

In contrast, when the protein in the existing soybean milk powder is absorbed and utilized by the human body, it often needs to be converted into amino acids in the body first, then synthesized into polypeptides, and then absorbed by the small intestine, which has the disadvantage of slow absorption and utilization; the human body needs to consume its own Therefore, for infants and young children with immature digestive system, the elderly whose digestive system has begun to degenerate, and athletes and physical workers who urgently need nitrogen sources due to excessive exercise but cannot increase the burden of gastrointestinal function, It is not advisable to supplement the amino acids needed in the body by directly eating protein-containing foods, that is to say, the existing soybean milk powder is not suitable for these groups of people
