The content of protein in soybean protein isolate is over 90%, and there are nearly 20 kinds of amino acids, which contain essential amino acids for human body. Rich in nutrition and free of cholesterol, it is one of the few plant protein varieties that can replace animal protein.
Studies have shown that daily intake of 25g soy protein can effectively reduce the contents of total cholesterol and low-density lipoprotein cholesterol in human blood, thus reducing the risk of heart disease.
Extended data:
There are two ways to classify the existing forms of soy protein isolate, one is based on sedimentation index. After high-speed centrifugation, soybean protein can be divided into four grades according to the centrifugal sedimentation index: 2S, 7S, 1 1 S, 15S***4 *, of which 7S and 1 1S are the main components, accounting for about 50% of globulin.
The other is classification based on immunological characteristics. It can be divided into four categories: A- concentrated globulin (about 15%), 13- concentrated globulin (about 28%), Y- concentrated globulin (about 3%) and soluble globulin (about 40%).
