General Description
Basic Information
Rice Protein Peptides are small-molecule peptide chains extracted from rice protein using enzymatic hydrolysis technology. They are easily absorbed, have low allergenicity, and possess various biological activities. The latest clinical research in 2026 has confirmed their significant potential in assisting in lowering blood pressure and reducing inflammation.
Rice peptides are not only a high-quality nutritional supplement but are also widely used in food flavoring, skincare, and medical foods. They are suitable for people with weak digestive function, those who need to control their blood pressure, or those seeking a low-allergenic protein source.

Core Efficacy and Health Value of Rice Peptides
1. Assisting in Regulating Blood Pressure: Overseas clinical trials published in March 2026 showed that supplements containing specific rice peptides (such as Leu-Arg-Ala) can reduce systolic blood pressure by an average of 7.5 mmHg after 12 weeks of continuous consumption, an effect approaching that of some dietary interventions. This is achieved by inhibiting angiotensin-converting enzyme (ACE) activity, thus helping to dilate blood vessels.
2. Antioxidant and Anti-aging: Rice peptides effectively scavenge free radicals in the body, reducing oxidative damage. Studies have found that their antioxidant activity is related to molecular weight, with smaller peptides (<1kDa) showing better results. Regarding skin health, cosmetics containing rice peptides, when used continuously for more than 4 weeks, help reduce wrinkles and inhibit melanin production.
3. Immune Regulation and Anti-inflammation: Overseas research in February 2026 indicated that peptides derived from wild rice can inhibit the secretion of gout-related inflammatory factors. Other studies have confirmed that rice peptide network components can reduce inflammation levels in the elderly and improve bodily functions.
4. Other Potential Benefits: Some studies suggest that rice peptides also have auxiliary effects in lowering blood sugar, cholesterol, and combating fatigue, helping to quickly recover physical strength after exercise.

Application
Corn Protein Peptide powder is mainly used in the food industry as a nutritional fortifier, in feed and feed health products to enhance nutritional components, and also has applications in cosmetics and other fields.
Main Application Areas:
1. Food and Nutritional Supplements: As a high-quality protein source, it is commonly used in protein powders, energy bars, and medical foods, especially suitable for those with lactose intolerance or gluten allergies. A recent study in March 2026 also found that rice peptides can significantly enhance the umami flavor of food; when used in conjunction with monosodium glutamate (MSG), it can nearly double the umami flavor, making it a natural flavor enhancer.
2. Cosmetics and Skincare: Utilizing its moisturizing, whitening, and anti-wrinkle properties, it is widely added to skincare products such as face masks and serums to help improve microcirculation and skin elasticity.
3. Pharmaceuticals and Healthcare: As a functional ingredient, it is used to develop health foods that help lower blood pressure and regulate immunity, or to function in drug carriers.
