It is a small molecule active peptide obtained by biosynthetic enzyme digestion technology using pea protein as raw material. Pea peptide completely retains the amino acid composition of pea, and contains 8 essential amino acids that the human body cannot synthesize by itself, and its ratio is close to the recommended model of FAO/WHO (United Nations and World Food and Agriculture Organization (WHO). The FDA considers peas to be the cleanest plant-based product, with no risk of GMOs. Pea peptide has good nutritional properties and is a promising safe functional food material.
