PURPOSE:To provide the subject composition which comprises an antidiffusing active ingredient obtained by extracting a fruit of Myica rubra Sieb et Zucc with an organic solvent and a resin acid, and shows excellent antioxdant effect on a variety of fat and oil with thermal stability, thus preventing food products or the like from being deteriorated by oxidation. CONSTITUTION:The subject composition comprises (A) an active ingredient of antioxidizing properties which is extracted from a plant, Myrica rubra Sieb et Zucc, with an organic solvent such as 1 to 5 C aliphatic alcohol and/or other organic solvents and (B) a compound selected from aliphatic carboxylic acids and their derivatives, preferably at a ratio of 1 pt. of (A) to 0.1 to 10 pts. Component (A) is obtained by extracting the dried barks with methanol, concentrating the extract to dryness under reduced pressure. Then, the solid is crushed, suspended in water, filtered. Further, the residual slid is further washed and dried under reduced pressure. Component B is preferably citric acid, malic acid, their sodium salts or their glycerides. |
