What is the difference between soy peptide, soy protein isolate, and soy phospholipid?

Soy peptide

The composition of soy peptides is almost the same as that of soy protein, and it also has the characteristics of balanced amino acid ratio and rich content.

Compared with soy protein isolate, soy peptides have many advantages. Their main difference lies in absorbability, biological activity, range of action and nutrition.

1. Soy peptides have the characteristics of no beany flavor, acidity, no precipitation, heating and non-solidification, and easy to dissolve in water.
2. Soy peptide has a good absorption rate in the intestinal tract, and its digestibility and absorption are better than soy protein.
3. Soy peptides have active groups that effectively combine with calcium and other trace elements, and can form organic calcium polypeptide complexes, which significantly improve solubility, absorption rate and delivery speed, and can promote the passive absorption of calcium.

Soy peptides also have anti-oxidation, lowering blood pressure, anti-fatigue, lowering blood fat, weight loss and other effects.

 

Soy protein isolate

Soy protein isolate is obtained by using high technology to remove soybean oil and water-soluble non-protein parts from dehulled soybeans. It is a high molecular organic polymer composed of a series of amino acids combined by peptide bonds.

Mainly composed of albumin and globulin, it contains essential amino acids for human body, among which the protein content is more than 90%, and there are nearly 20 kinds of amino acids.

The main advantage is that compared with other proteins, the digestion rate is the highest in the body, and the digestibility of soy protein isolate is 93%-97%. It is rich in nutrients and does not contain cholesterol. It is one of the few vegetable protein that can replace animal protein.

 

Soy phospholipid

Soybean phospholipid is a kind of mixed phospholipid, which is composed of phosphatidylcholine (lecithin), phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol and other components. It is one of the components of cells.

It can effectively enhance cell function, improve cell metabolism, enhance the ability of cells to eliminate lipid peroxides, and timely supply the energy needed by the human body, making people energetic and not easy to fatigue.
