Introduction of soy protein isolate


Soy protein isolate is a full-price protein food additive produced from low-temperature desolubilized soybean meal. The protein content of soy protein isolate is more than 90%, there are nearly 20 kinds of amino acids, and it contains essential amino acids. It is rich in nutrition and does not contain cholesterol. It is one of the few varieties of plant protein that can replace animal protein.


The United States is the first country in the world to conduct research and industrial production of soy protein isolate (SPI). It began research in the 1940s and developed soy protein isolate in the 1950s. It started production in the 1960s, and its production technology gradually became more and more in the 1970s. For perfection and maturity. The international protein isolate market is basically monopolized and controlled by the United States. In addition, Japan, Germany, Brazil and other countries also occupy a certain share in the international market. In 1998, the world's output of soy protein isolate was about 700,000 tons, and the United States produced about 350,000 tons, accounting for 50%. my country began to study the production and application technology of soy protein isolate in the 1970s, and began to produce soy protein isolate in the early 1980s. The production and development of soybean protein isolate in our country are closely related to the rapid development and increase in demand of the food industry, especially meat products (such as Western-style ham). By 1998, the domestic demand for soy protein was nearly 30,000 tons. So far, there are about 26 soybean protein isolate production enterprises in China that have been established or are under construction, with a total design capacity of nearly 30,000 tons. However, in 1998, the total amount of soy protein isolate produced by domestic manufacturers and entered the market was only about 11,000 tons. Nearly 2/3 of the market was still occupied by the products of American Polytech International and ADM, which caused a serious impact on the domestic soy protein isolate market. Bring a lot of pressure to the enterprise.

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
