Description
Technical Field
The invention relates to the field of food with special medical application, in particular to a preparation method of a protein component.
Background
Proteins are essential substances for life. The protein, carbohydrate and fat are called three major energy nutrients, and the main function of the protein is to keep the balance of body fluid and electrolyte; support body growth and turnover; synthetases, hormones and other compounds; synthesizing an antibody; maintaining acid-base balance, etc. When the human body lacks protein, the human body shows various symptoms. Clinical surgery patients are generally suffered from protein-calorie deficiency malnutrition according to research, and 40 percent of hospitalized patients are reported to have malnutrition before admission. Protein malnutrition occurs primarily because the body for some reason has reduced or malabsorption, increased consumption or increased demand for protein. The high protein diet can be applied to patients with malnutrition, preoperative and postoperative symptoms, hypoproteinemia, anemia, tuberculosis and the like caused by various reasons. Such patients should increase the protein in their diet on the basis of sufficient energy supply. Commonly used sources include: casein, whey protein and egg white protein, wheat, soybean protein, etc.
The isolated whey protein powder (WPI) (the purity is more than or equal to 90.0 percent) is used as concentrated whey protein extracted from milk, has high nutritional value, contains various active protein components, has higher purity than common protein powder, is more beneficial to the digestion and absorption of gastrointestinal tracts, and is one of the accepted best quality protein supplements for human bodies. The Soybean Protein Isolate (SPI) belongs to complete protein, has abundant resources and comprehensive nutrition, has a digestibility and a protein efficacy ratio close to those of milk, beef and eggs, and has a digestibility rate as high as 84-98 percent. Soybean Isoflavone (SI) is an important food ingredient of soybean as a phenolic compound.
The existing protein powder has complex components, and many unnecessary components can be brought in while protein is supplemented. Meanwhile, partial nitrite may be brought in by taking the physiological characteristics of the soybeans, the production process of the soybean protein isolate and other factors into consideration. Under appropriate conditions, nitrite can react with amines, which are decomposition products of proteins in food, in vivo and in vitro to generate nitroso compounds. Nitroso compounds are one of the most prominent carcinogens in humans. Because the application scene of the protein component is special, the content level of nitrite contained in the isolated soy protein should be considered.
Disclosure of Invention
Based on the above, the invention aims to overcome the defects of the prior art and provide the preparation method of the protein component, which has the advantages of simple component ingredients, clearer components, safer and controllable quality, capability of effectively and safely supplementing protein to a human body and convenience for doctors or clinical dieticians to apply.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a method for preparing a protein module, comprising the steps of:
(1) uniformly stirring and mixing the isolated soy protein powder and the soy isoflavone to obtain a mixture A, adding deionized water into the mixture A, and standing to obtain a mixed solution A;
(2) adding whey protein isolate powder into the mixed solution A obtained in the step (1), uniformly stirring, and carrying out centrifugal filtration to obtain mixed solution B;
(3) carrying out vacuum freeze drying on the mixed solution B, and screening to obtain powder with uniform particle size;
(4) and (4) adding powdery silicon dioxide into the powder obtained in the step (3), and uniformly mixing to obtain the protein component.
According to the method, the soybean protein isolate is pretreated, and the soybean protein isolate powder and the soybean isoflavone are uniformly stirred, so that the risk of nitrite residue is reduced; the preparation method provided by the application improves the material fluidity to a certain extent, and is beneficial to the subsequent mixing and subpackaging process.
Preferably, in the step (1), the weight ratio of the isolated soy protein powder to the soy isoflavone is as follows: isolated soy protein powder: soy isoflavones ═ 1: (40-50); in the step (1), the weight ratio of the mixture A to the deionized water is as follows: mixture A: deionized water as 1, (5-10); the temperature during standing is 10-40 deg.C, and the time during standing is 30-60 min.
Preferably, the weight ratio of the whey protein isolate in the step (2) to the soybean protein isolate in the step (1) is as follows: whey protein isolate powder: isolated soy protein powder ═ 1-2: (2-3). The application improves the using amount of the soybean protein isolate, avoids the risk of the soybean protein isolate as much as possible, effectively enlarges the advantages lacking in animal protein, and provides a high-quality protein component through the proper proportion of the plant protein and the animal protein. Preferably, in the step (2), the rotation speed of the centrifugation is 3000r/min, and the time of the centrifugation is 10-20 min.
Preferably, the soy protein isolate has protein content of 83 wt% or more, water content of 6 wt% or less, ash content of 5 wt% or less, fat content of 0.5 wt% or less, sodium content of 1.5 wt% or less, potassium content of 0.3 wt% or less, phosphorus content of 1.2 wt% or less, copper content of 0.002 wt% or less, chlorine content of 1 wt% or less, lead content of 0.5ppm or less, arsenic content of 0.5ppm or less, and cadmium content of 0.2ppm or less.
