Consumer Advice
Ascorbyl palmitate is a fat-soluble antioxidant made by combining vitamin C with palmitic acid. It dissolves in oils and fats to prevent oxidation and rancidity in cooking oils, pastries and crisps. It is closely related to vitamin C, has a good safety profile and is harmless at authorised levels. A few consumers may wish to consider the source of the palmitic acid, but there are no known health risks.
