Can soy protein lower cholesterol?

 There has been controversy surrounding soy protein and its effect on cholesterol. A new meta-analysis delved into existing data and concluded that protein can indeed reduce "bad" cholesterol levels.

Soy protein comes from soybeans. It has high protein content, but does not contain cholesterol and only contains low levels of saturated fat. It is one of the few plant foods containing all essential amino acids.

Currently, the US Food and Drug Administration (FDA) includes soy protein in its list of foods that can lower cholesterol.

Of the 46 studies selected by the FDA, 43 provided enough data to be added to the scientist’s analysis. A total of 41 studies specifically looked at low-density lipoprotein (LDL) cholesterol, commonly referred to as bad cholesterol.

LDL cholesterol has a bad reputation because it increases the risk of stroke and heart disease when it accumulates in the arteries. Any food that can reduce this risk is very interesting.

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
