Gamma Oryzanol, also known as rice bran, is a natural organic compound rich in rice bran oil. The content of rice bran oil is generally 2% to 2.5%. It consists mainly of a mixture of various cyclic ferulates. The composition of oryzanol contains ferulic acid structure, so it has good antioxidant activity, and as a product processed from natural raw materials, its safety is much higher than the widely used synthetic antioxidants BHA and BHT.
Through a lot of clinical practice, oryzanol has the functions of protecting the skin, lowering blood sugar, inhibiting the synthesis of cholesterol in the body, lowering the content of serum cholesterol, regulating autonomic nerves, and improving gastrointestinal function. In cosmetics, oryzanol has a significant effect on freckle removal. As a food additive, oryzanol has a good antioxidant effect, and its safety is much higher than that of synthetic antioxidants (such as butyraldehyde ether), so it can be widely used in the food field as a substitute for synthetic antioxidants.
Application of oryzanol
1. As a food antioxidant, it is used in food and preservation. Because oryzanol has superior antioxidant activity and safety than commonly used food antioxidants BHT and BHA. Makes it useful as a replacement for BHT and BHA
2. As a plant preservative. Because oryzanol has the effect of inhibiting tyrosinase activity, it can be used as a preservative for mildew-prone vegetables (such as potatoes, mushrooms, etc.).
3. Oryzanol has the pharmacological effects of treating women's menopausal syndrome, vascular analgesia and regulating autonomic function. In addition, oryzanol can also be used to produce pharmaceutical preparations for the treatment of related diseases.
4. Used as cosmetic auxiliaries in cosmetic production. Oryzanol has the effect of inhibiting melanin production and reducing the conversion of tyrosine to 2,1-dihydroxyalanine, so it can be used as a daily chemical to prevent the formation of pigmentation.
