Fat and vitamin A stability in the presence of Ronoxan A and other antioxidants.
The effect of the antioxidant Ronoxan A and of two of its components (ascorbyl palmitate, lecithin) and of tocopheryl acetate was tested for the stabilization of fats and retinyl acetate. In the present study, results obtained in sunflower oil, soybean oil, milk fat and in the mixtures of these fats in concentrations corresponding to their levels in the Czechoslovak Infant Formula (Feminar) are compiled. The antioxidant levels applied, i.e. those used in Czechoslovakia for the stabilization and enrichment of vegetable oils and Feminar, have a protective effect on retinyl acetate to a certain extent as well, and in no case they affect it unfavourably. All antioxidant combinations applied cause a significant retardation of the fat autoxidation. Ronoxan A has the best effect in all cases tested.
