Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C, it is also used as an antioxidant food additive (E number E304). It is approved for use as a food additive in the EU,[1] the U.S.,[2] Canada,[3] Australia, and New Zealand.[4]
Ascorbyl palmitate is also marketed as "vitamin C ester". It is synthesized by acylation of vitamin C using different acyl donors.[5]
