Factory Price Powder CAS. 9010-10-0 Isolated Soy Protein (SSPI-90I)

Soybean protein isolate (SPI) is a kind of protein powder which contains more than 90% protein after the soybean meal is extracted in alkaline solution under low temperature, and then precipitated, washed and dried. Its structure and properties basically replace the pure soybean protein. There are nearly 20 kinds of amino acids in soy protein isolate, and it contains essential amino acids for human body. It is nutritious and cholesterol free, and is one of the few plant proteins that can replace animal protein.

Emulsibility

Soy protein isolate is a surfactant, which can reduce the surface tension of water and oil as well as water and air. It is easy to form stable emulsion. In the production of baked food, frozen food and soup food, the addition of soy protein isolate as emulsifier can make the product stable.

Hydration

Soybean protein isolate contains many polar groups along its peptide chain skeleton, so it has water absorption, water retention and expansibility. The water absorption of protein isolate is much stronger than that of protein concentrate, and is almost not affected by temperature. The protein isolate also has the ability to maintain water during processing, and the maximum water retention capacity is 14g water/g protein.

Oil absorption

When protein isolate is added to meat products, it can form emulsion and gel matrix to prevent fat from moving to the surface, thus playing a role in promoting fat absorption or fat binding, reducing the loss of fat and juice during meat product processing, helping to maintain the stability of the appearance. The oil absorption rate of protein isolate is 154%.

Gel

It makes the separated protein have high viscosity, plasticity and elasticity, which can be used as the carrier of water, flavor agent, sugar and other complexes, which is extremely beneficial to food processing.

Foaming property

Among soybean proteins, protein isolate has the best foaming property, which can give food a loose structure and a good taste.
