They are harvested in summer when the flower buds form, and then processed through drying, extraction, purification, and other procedures.

Primary Applications in the Food Sector

I. Natural Food Antioxidant

Quercetin is one of the most effective natural antioxidants, possessing strong free radical scavenging ability. In the food industry, quercetin can be used as a natural antioxidant in oils, fats, and fat-containing foods to delay lipid oxidation and rancidity. Studies have shown that adding quercetin and its derivatives (such as rutin) to oils and fats can significantly extend the product's shelf life.

II. Functional Food Ingredient

Quercetin can interact with starch molecules through hydrogen bonding, retarding starch retrogradation and improving thermal stability. This has practical value for developing retrogradation-resistant rice-based and wheat-based products, as it can improve product texture while enhancing its nutritional functionality.
