Problems solved by technology

However, since the molecular weight of most soybean proteins is more than 100,000, and the molecular internal structure is complex, the digestibility of soybean protein is far lower than that of animal proteins such as milk and eggs; moreover, soybean protein (especially 7S and 2S) has certain antigenicity. The disadvantage of allergenicity greatly reduces its nutritional value; soybean protein has low solubility and cannot be used as a functional ingredient in food systems such as dairy products, beverages, and candies, all of which greatly limit the application fields of soybean protein

Embodiment 1

[0171] As shown in the accompanying drawing, the steps to prepare 10kg of double protein-based polypeptide soybean milk powder are as follows:

[0172] 1) Prepare soybeans and perform soybean pretreatment:

[0173] ①Removing impurities to remove impurities in soybeans. According to the principle of specific gravity, sieve out soil, sand and metal in soybeans. At the same time, remove miscellaneous beans and rotten beans, and the removal rate reaches 99%;

[0174] ②Baked beans The baked beans are baked at a temperature of 95°C. After drying, the moisture content of the soybeans is 7.5%, the temperature of the baked beans is uniform, and the local temperature difference is less than 0.2°C; the passivation rate of lipoxygenase reaches 90%, preventing the product from producing beany smell;

[0175] ③The skin and germ of the peeled and dried soybeans fall off under a certain shear force, so that the peeled watercress and soybean skin are separated, and the peeling rate reaches 99%...

Embodiment 2

[0222] The production process of the double-protein-based polypeptide soybean milk powder in Example 2 is basically the same as that of the double-protein-based polypeptide soybean milk powder in Example 1. The difference between the two is:

[0223] Embodiment 2 is from the soybean milk containing soybean polypeptide obtained in Example 1, that is, after the enzyme is inactivated in step 10), the soybean milk containing soybean polypeptide with a dry weight of 3.5 kg is taken out for nutritional preparation; during the nutritional preparation process , the weight of other raw materials is as follows: whole milk powder 2.5kg, maltose syrup 1.8kg, white sugar 1.1kg, edible soybean oil 0.4kg, soybean cellulose 0.4kg, soybean oligosaccharide 0.2kg, edible calcium carbonate 0.1kg;

Embodiment 3

[0225] The production process of the double-protein-based polypeptide soybean milk powder in embodiment 3 is basically the same as that of the double-protein-based polypeptide soybean milk powder in embodiment 1. The difference between the two is:

[0226] Embodiment 2 is from the soybean milk containing soybean polypeptide obtained in Example 1, that is, after the enzyme is inactivated in step 10), the soybean milk containing soybean polypeptide with a dry weight of 3.8 kg is taken out for nutritional preparation; during the nutritional preparation process , the weight of other raw materials is as follows: whole milk powder 2.2kg, maltose syrup 1.6kg, white sugar 1.3kg, edible soybean oil 0.5kg, soybean cellulose 0.2kg, soybean oligosaccharide 0.3kg, edible calcium carbonate 0.1kg;

Abstract

The invention discloses a dual-protein based polypeptide soy-bean milk powder and a preparation method thereof. The dual-protein based polypeptide soy-bean milk powder adopts the following raw materials by weight percentage: 30-45 percent of soy-bean milk containing soy-bean polypeptide (calculated by dry weight), 20-30 percent of milk powder, 15-30 percent of malt syrup, 10-20 percent of white sugar, 3-10 percent of edible soy-bean oil, 2-5 percent of soy-bean cellulose, 1-4 percent of soy-bean oligosaccharides and 1 percent of edible calcium carbonate. The dual-protein based polypeptide soy-bean milk powder is prepared by the following steps of: using the raw materials mentioned above: (1) preparing the soy-bean milk containing soy-bean polypeptide, (2) mixing nutrients, (3) high-pressure homogenizing and refining, and (4) spraying and drying. The invention takes soy-bean as main raw material, therefore, the cost is low; soy-bean not only provides soy-bean protein and parts of soy-bean protein is turned into soy-bean polypeptide by enzymolysis, therefore, the source of raw materials is rich. The dual-protein based polypeptide soy-bean milk powder has abundant nutrients and smooth, aromatic and pure mouth feel and no bean tastes basically.

Description

Technical field: [0001] The invention relates to a soybean milk powder and a preparation method thereof, more specifically, to a polypeptide soybean milk powder based on double protein of plant protein and animal protein and a preparation method thereof. Background technique: [0002] Protein is the basic substance of living organisms and the basis for the formation of living tissues. Protein is also the main component of cells and tissues of all organisms, and the material basis of the shape and structure of organisms; all organisms, from the simplest virus to the most For advanced human beings, their ever-changing proteins are all composed of the same 20 kinds of amino acids, which constitute a world of proteins in various poses and with different expressions. Many people know that protein is related to nutrition. Reasonable nutrition of the human body can improve human health. If the nutrition of the human body is insufficient or unbalanced, if things go on like this, abn...
