To minimize the degradation of vitamin A,
industry employs commercially available esters wich are more
stable, such as retinyl palmitate or acetate for food fortification.
Also antioxidants may be added to vitamin A such as butylated
hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and a-tocopherols (vitamin E) to improve the stability during exposure to
light or oxygen
