METHOD FOR STABILIZING OIL-AND-FAT

摘要

PROBLEM TO BE SOLVED: To provide a method for stabilizing oil-and-fat capable of stably sustaining an oil-and-fat containing conjugated unsaturated fatty acid(s) over a long period through inhibiting its oxidative deterioration. SOLUTION: This method for stabilizing oil-and-fat comprises the steps of transesterification between an oil-and-fat containing conjugated unsaturated fatty acid(s) and another oil-and-fat and then adding cuttlefish-derived lipid and/or tea extract to the resultant transesterified oil-and-fat.
