Soybean peptides, which derived from hydrolysis of soybean protein by acid, alkali or enzyme,were the general name of a group of peptides chain with different amino acid composition. Themolecular weight rang of them was defined from 300 to 1000Da with 3~10 amino acid now. They werealso defined as soybean bioactivity peptide or soybean functional peptide due to their good processfunction and bioactivity beneficial to human body and focused by researchers for their potential offunctional food.
