Description

Rice Oligopeptide is a highly bioavailable small-molecule peptide ingredient derived from rice protein using compound bio-enzyme directional hydrolysis and precision low-molecular-weight separation technology. As a superior dietary peptide source, Rice Oligopeptide provides excellent nutritional, functional, and physiological benefits, making it ideal for applications in global nutrition, functional food, health supplements, sports nutrition, anti-aging products, cosmetics, and pharmaceutical formulations.

Rice protein, the raw material, is a natural, hypoallergenic, and nutritionally balanced plant protein. With amino acid compositions close to that of high-quality animal proteins, rice protein is recognized as one of the most digestible and absorbable plant proteins. The enzymatically hydrolyzed rice oligopeptides maintain the inherent nutritional advantages while further enhancing solubility, absorption, and physiological functionality.

Scientific studies show that Rice Oligopeptide demonstrates strong free radical scavenging activity and effectively inhibits lipid and oil peroxidation, offering excellent anti-aging and cellular protection benefits. Its ACE-inhibitory peptides make it highly suitable for blood pressure management products. Additionally, immune-boosting peptides in the composition can enhance leukocyte phagocytic activity, supporting immune system balance and resilience.
