Description

Ascorbyl Palmitate is a white or yellowish-white powder. It has slightly citrus smell. It is very soluble in water and vegetable oils, soluble in ethanol.

Application

Ascorbyl palmitate can be obtained by esterification of palmitic acid and ascorbic acid. It is a fat- soluble antioxidant that can prevent the formation of oil peroxides and delay the oxidation and deterioration of animal oil, vegetable oil, fish, margarine, milk and carotenoid. The effect is better than BHA and BHT.

Compared with ascorbic acid, ascorbyl palmitate has significantly enhanced antioxidant effect, because of the insertion of palmitic acid group, it has hydrophilic ascorbic acid group and lipophilic palmitate group, and then becomes a high-quality surfactant.

Ascorbyl palmitate can be used in oily foods, edible oils, animal and vegetable oils and advanced cosmetics. It can also be used in various infant foods and milk powders. It has antioxidant and nutritional strengthening functions and is widely used in food, cosmetics and medical health products.
