Adzuki bean extract is rich in polyphenols such as hydroxybenzoic acid, quercetin, saponin, etc., and has good antioxidant effect. Free radicals such as DPPH and ABTS+ inhibit lipid peroxidation. Studies have shown that the phenol content in the extract can reach 3% - 5%. After being made into powder, the concentration process further increases the concentration of the active ingredient, and its antioxidant effect reaches 2 to 3 times that of the raw material.
2. Dietary fiber and oligosaccharides
Contains water-soluble dietary fiber such as β-glucan and insoluble dietary fiber, which can regulate intestinal flora and promote the proliferation of probiotics. , It also contains oligosaccharides such as maltose and sucrose.

The development of auxiliary intervention products for joint health and metabolic syndrome is suitable for.
Liver protection effect: The isoflavone components contained in adzuki bean extract can improve glycogen synthesis in the liver and reduce liver damage caused by alcohol and drugs, and are expected to be used in liver protection health products.
3. Cosmetics and personal care fields
Antioxidant and anti-aging: Polyphenol components penetrate the epidermis, inhibit the activity of collagenase (mp1), and inhibit the formation of wrinkles. Adzuki bean essence powder has improved transdermal absorption rate through nano-processing and is often used in anti-aging creams and beauty essences.
Calming and moisturizing effects: The moisturizing gel formed by dietary fiber has moisturizing and water-retaining effects. Combined with the anti-inflammatory effect of flavonoids, it is suitable for skin care products for sensitive skin, reducing skin problems such as redness and dryness.
