Provided are a novel method of suppressing heat discoloration of lecithin, and a novel lecithin or lecithin preparation having resistance to heat discoloration. The method to suppress heat discoloration of lecithin, comprises: adding a fatty acid metal salt to lecithin; and the lecithin or lecithin preparation having resistance to heat discoloration, containing a fatty acid metal salt. The metal constituting the fatty acid metal salt is preferably at least one selected from the group consisting of lithium, beryllium, sodium, magnesium, aluminum, potassium, calcium, iron, cobalt, nickel, copper, zinc, silver, barium, thallium, and lead; and the fatty acid of the fatty acid metal salt is at least one selected from saturated fatty acids and unsaturated fatty acids having 3-36 carbon atoms. |
