Application areas
Food industry
Dihydroquercetin has become a new food additive because of its unique antioxidant activity and biological activity. It is used as a food additive to preserve food raw materials and the food itself and has antiseptic and preventive treatment properties. In this field, the antioxidant properties of dihydroquercetin act as powerful inhibitors that are comparable to or superior to many existing antioxidants, whether synthetic or natural and are non-toxic and non-allergenic.
Adding dihydroquercetin to vegetable oil, animal fat, dry milk powder, and fat-containing confectionery and snack foods can extend the validity period by 2 to 3 times, and under these conditions, the food can significantly show improved performance.
Pharmaceutical industry
In the field of medicine, as a compound with significant anti-inflammatory effects, dihydroquercetin has been proven to be beneficial to a variety of inflammatory diseases, such as arthritis and dermatitis. Its unique anti-inflammatory mechanism lies in its ability to regulate key steps in the inflammatory response, thereby reducing the damage caused by inflammation to the body.
Dihydroquercetin also plays an important role in cardiovascular health. It can significantly lower blood pressure, improve blood lipid metabolism, and provide a new strategy for the prevention and treatment of cardiovascular diseases. Its cardiovascular protective mechanism may be related to multiple biological effects such as antioxidant, anti-inflammatory, and anti-platelet aggregation. These mechanisms work together to help maintain the health of the cardiovascular system.
