Abstract
A fat is protected from oxidation by, in one process embodiment, forming a mixture of tocopherol and lecithin at a temperature not greater than 60.degree. C., mixing ascorbic acid dissolved in a polar solvent into the tocopherol and lecithin mixture, eliminating the solvent from the mixture at a temperature not greater than 60.degree. C. and then, incorporating the mixture into a fat. In another embodiment, lecithin is added to a fat, and tocopherol and ascorbic acid dissolved in a polar solvent are added to the lecithin-added fat after which, the solvent is eliminated from the fat.

A process for protection of a fat against oxidation comprising stirring tocopherol and a lecithin at a temperature not greater than 60.degree. C. to form a mixture, dissolving ascorbic acid in a polar solvent to form a solution, mixing the dissolved ascorbic acid solution into the tocopherol and lecithin mixture, eliminating the solvent from the tocopherol, lecithin and ascorbic acid solution mixture at a temperature not greater than 60.degree. C. and then incorporating the mixture into a fat.
A process for protection of a fat against oxidation comprising adding a lecithin to a fat, dissolving tocopherol and ascorbic acid in a polar solvent to form a solution, adding the tocopherol and ascorbic acid solution to the lecithin-added fat and then eliminating the solvent from the fat.
