Abstract
Abstract This invention relates to an antioxidizing composition which comprises an antioxidant such as tocopherol, BHT or BHA; condensed phosphate such as pentapolyphosphate; and citric acid. The antioxidizing composition has antioxidant action superior to conventional compositions and has good compatibility with fat, oil and food containing fat or oil. The antioxidizing composition preferably comprises tocopherol, lecithin, pentapolyphosphate and citric acid.
