Soybean protein food

  Soybeans are high in protein content and rich in nutrients, generally containing 30%-50% protein. Soy protein contains 8 kinds of essential amino acids for human body, and the ratio is reasonable, but lysine is relatively higher, and the content of methionine and cysteine is lower. At present, soy protein has become an important protein resource. In particular, soy protein isolate contains more than 90% protein and is an excellent food material.  

  Lamb is very nutritious, rich in vitamins and minerals such as calcium, phosphorus, iron, and low in fat and cholesterol. It is a healthy animal food. Because soy protein isolate can partially replace animal protein, it is currently the most widely used in meat processing. The addition of soy protein isolate in meat products can not only increase the protein content, but also improve the protein ratio, making the meat nutrition more comprehensive and reasonable. Utilizing the gelatinity and cohesiveness of soy protein isolate can improve the structure of meat, enhance its toughness, and have a better taste. It can also make use of its emulsification and water absorption, and prevent the precipitation of fat and water by combining with fat and water, and reduce the loss during the cooking process of meat products.  

  Whether it is a "big jar" protein powder for muscle gain, or a "small piece" protein powder for immune enhancement. In the past, as long as protein powder was mentioned, people often thought of animal-derived protein first, followed by vegetable protein such as soy protein. It is even more arbitrary that plant-derived protein cannot be compared with animal-derived protein. However, in the market, the increasing number of protein powders with soy protein isolate as the main raw material also shows an indisputable fact. Plant protein is attracting more and more protein powder manufacturers' attention? In view of this, the editor has to ask, do you really know soy protein isolate ?

Soy protein concentrate is made from soybeans. After crushing, peeling, extracting, separating, washing, drying and other processing techniques, the oil, low-molecular soluble non-protein components (mainly soluble sugar, ash, alcohol) in soybeans are removed. Soybean deep-processed products obtained after soluble protein and various odor substances, etc.). There are four main production processes for soybean protein concentrate, namely, moist heat extraction.

Soy protein is a plant protein. The amino acid composition of soy protein is similar to that of milk protein. Except for methionine, which is slightly lower, the content of other essential amino acids is relatively rich. It is a plant-based complete protein. In terms of nutritional value, it can be equivalent to animal protein. It is also the closest to human body in terms of genetic structure. Amino acids, so it is the most nutritious plant protein.

Foreword: Soy protein isolate has been widely used in meat products. Although my country ’ s protein isolate production capacity has developed rapidly, production technology has not improved significantly, product quality has stagnated, and multi-variety, multi-functional, and serialized products have not yet been formed. The high-nutrition and high-value-added product characteristics of soy protein have not been fully reflected, and the market price has been in a downturn. Moreover, the domestic protein isolate has a single variety with little functional difference, and the product quality cannot meet customer requirements. Hundreds of foreign soybean protein isolate products can be produced, which are widely used in various industrial fields. Because of the variety and good quality of foreign products, although the price is much higher than that of domestic products, they still occupy about 1/3 of the domestic market.

  The main functions and functions of protein powder 1. Supplement the source of nutrition Protein is the main source of nitrogen in the human body. It can not only provide part of the energy consumed, but also be used to synthesize new tissues. In adults, protein accounts for about 17% of body weight, and 3% of protein participates in metabolic renewal every day. Infants, young children, adolescents, pregnant women, and lactating women, in addition to maintaining the renewal of tissue proteins, they also need to synthesize new tissues. When there is insufficient protein in the body, people ’ s basic life activities will be affected, which can lead to children and adolescents with growth retardation, underweight, and mental retardation; adults will experience fatigue, weight loss, anemia, decreased plasma albumin, and even edema; It can also cause menstrual disorders in women. Eating protein powder can effectively prevent or improve these symptoms.   2. Prevent disease Heart disease is

Protein powders generally use purified soy protein . For healthy people, protein deficiency generally does not happen. Too much protein intake is not only a waste, but also harmful to human health.

  With the increase in the amount of soy protein isolate added, the yield of sausages also increased. By studying the effect of soy protein isolate on the yield and texture characteristics of the product during sausage processing, it was found that when the amount of soy protein isolate added was 2% to 3 %, the hardness, cohesion and elasticity of the sausage are better, and the texture characteristics of the sausage can be significantly improved by adding an appropriate amount of soy protein isolate.
