Soy protein powder is a nearly purified protein extracted from soybeans through a series of processing steps. In the production process, it is necessary to screen and remove impurities from the soy protein powder, that is, to screen out impurities, lumps, and agglomerates from the soy protein powder through a high-quality vibrating screen, and it also has the function of loosening materials to ensure the purity of the semi-finished soy protein powder raw materials.

Soy protein isolate contains eight kinds of amino acids required by the human body, which is similar to meat, fish, eggs, and milk, and is a complete protein. Studies have shown that protein is the material basis of life and one of the three major components of the human body. Protein deficiency can directly lead to slow growth and development, low immunity, loose skin and premature aging. Among the many plant proteins, bean protein (also known as soy protein) has high nutritional value, and bean food does not contain cholesterol, which is a feature that animal food does not have. Soy protein that has not been processed has its defects: the content of methionine (a required amino acid) is relatively low. Therefore, the amino acid score of whole soybeans is about 0.6 to 0.7. However, because soybeans are high in protein and contain no cholesterol, soy protein powder is widely used.


Production process

The leaching process, acid precipitation separation process, neutralization process, flash evaporation process and drying process, the dried soybean protein powder must be cleaned before packaging, and it can be packaged only after screening.


Screening purpose

This screening and impurity removal process plays a safeguard role in screening out impurities, lumps and clusters from the soy protein powder. It also has the function of loosening materials to ensure the purity of the semi-finished soy protein powder raw materials.
