Plant protein powder vs animal protein powder

Abstract: People often say that animal protein powder is better than plant protein powder, because animal protein powder contains more essential amino acids, especially leucine, an amino acid that initiates protein synthesis, so it is better for muscle building.

But nowadays, more and more vegetarians, or like me, cannot drink the common whey protein on the market because they are intolerant to lactose. So today we will take a look, for vegetarians and lactose intolerant people, can plant protein powder help achieve the same muscle-building effect?

 There are three most common plant protein powders: soy protein, pea protein and brown rice protein.


Soy Protein

The amino acid content of soy protein, except leucine, is not worse than whey protein or casein.

We know that leucine is the most important amino acid for muscle gain because it can directly stimulate protein synthesis. And if we just look at some short-term studies (that is, look at the changes brought about by the protein within a period of time after it enters the body), animal protein is indeed better than soy protein. For example, scientists have found that after consuming whey protein, the protein synthesis rate is 18-31% faster than soy protein.

Use of soy silk drawing protein

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
