Application of Soy Protein Concentrate in Animal Feed

Abstract: 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 solubilizing protein and various odor substances, etc.). There are four main production processes for soybean protein concentrate, namely, moist heat extraction, acid washing, ethanol extraction and ultrafiltration membrane method.

Due to the elimination of oligosaccharide flatulence factors, trypsin inhibitors, lectins and saponins and other anti-nutritional factors, the nutrient digestibility of soy protein concentrate is improved to a certain extent, and the product flavor and quality are improved, which makes soy concentrate Protein has been very popular in the food industry and feed industry since its commercial production in 1959.

Quality standards and nutritional characteristics of soy protein concentrate

In January 1983, the Food and Nutrition Society of the United States Department of Agriculture established a quality standard that the protein content of soy protein concentrate is greater than 60%.

In 1987, the International Food Standards Committee and the Vegetable Protein Standards Committee passed the United Nations Food and Agriculture Organization/World Health Organization Joint Food Standards Regulations at the Havana meeting in Cuba, and proposed that the protein content of soy protein concentrate should be 65% to 90%.

Use of soy silk drawing protein

图片
The soy silk drawing protein is a fibrous plant protein with a texture similar to muscle fiber formed by the production and processing of soy protein through a special process. The classification of soy silk drawing protein is divided according to its structure. There are thick silk type, thin silk type, soft silk type, hard silk type, smooth silk, astringent silk, etc. According to the different silk structure and the tensile strength of the silk, how much A combination of plant silk protein can be used to produce ham sausage, minced meat, beef jerky and canned food. The taste of the food is basically the same as ordinary meat food, but the price of plant silk protein is only 1/of the lean pork. 5. The protein content is equivalent to 2-3 times that of fish, meat, and eggs.

 According to market needs, through the selection of different proteases, the adjustment of process conditions and the degree of hydrolysis, a variety of products with different functional characteristics can be developed and produced. (1)Injectable protein isolate :  The product is used in the salted solution for injection of whole meat products, which can reduce the cooking loss of meat products and improve the quality of individual rows and cut surfaces of meat products. Since the product is usually added in a relatively small amount, below 3%, it is not necessary to strictly control the bitterness. Such products are required to have a lower viscosity, and at the same time, the increase in foaming properties and the decrease in gel properties must be controlled within a certain range. The viscosity is mainly determined by the molecular mass of the protein. The greater the molecular mass, the greater the viscosity. 80% of soybean protein has a molecular mass of more than 100,000 and
