Introduction of soy protein concentrate


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. After solubilizing protein and various odor substances, etc.), the soy protein product containing 65% (dry basis) or more protein (N×6.25) is prepared.

The production methods of soy protein concentrate mainly include dilute acid precipitation method, alcohol washing precipitation method, wet and hot water washing method, acid leaching and alcohol precipitation method and membrane separation method. The common feature of these methods is: first use a certain method (such as heating, adding alcohol) to precipitate the protein in the soybean meal, and then separate the soluble components in the system, so as to achieve the purpose of increasing the protein content. The raw material for the production of soy protein concentrate is generally low-denatured defatted beans.

 

Food grade:

Meaning: With high gelling, emulsifying or high dispersibility, it greatly improves the comprehensive utilization rate and reduces the production cost. It is widely used in the production of processed meat foods, baked goods, ice cream, candy and beverages.

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.

How to use enzyme technology to modify soy protein?

 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
