Abstract

565,565. Stabilizing fats and oils. NATIONAL OIL PRODUCTS CO. Oct. 8, 1942, No. 14141. Convention date, Oct. 10, 1941. [Class 91] Oxidisable fats and oils which have been affected by oxidation are stabilised by subjecting the fatty material to a process for decomposing peroxides by heating under reduced pressure or treating with reducing agents and then adding an anti-oxidant. The oils concerned are particularly vitamin-containing fatty oils, preferably vitamin A ; fish liver oils are specified. In the purification step by heating under reduced pressure, a temperature of 135-200‹ C. or above may be used. The reduction method includes treatment of an acidified solvent solution of the material, e.g. an acetic acid-chloroform solution with potassium iodide and subsequent removal of the free iodine, excess K1, acid and solvent and also washing the material with an aqueous solution of sodium thiosulphate, sodium hydrosulphite or pyrogallol. The antioxidants may be chemical or natural products ; the chemical products specified comprise amino-phenols, other substituted phenols, ketols, hydroquinone and its derivatives, lecithin, eugenol, ethanolamine, thiourea and its substitution products, and acetyl and methyl carbinol. The natural products may be concentrates prepared from fats, oils and oily seeds and meals by the processes of Specifications 550,983 and 553,328.
