摘要:
It is intended to obtain highly active and fat-soluble antiradicals originating in a natural substance whereby the stability of foods (fat compositions) can be elevated and disorders caused by oxidation in vivo can be prevented simultaneously. Namely (1) an antiradical containing 4-vinyl-2,6-dimethoxyphenol as the active ingredient; (2) an antiradical comprising an extract of crude rapeseed oil containing 4-vinyl-2,6-dimethoxyphenol; (3) a crude rapeseed oil extract containing 4-vinyl-2,6-dimethoxyphenol in a concentrated state characterized by being prepared by treating crude rapeseed oil with an alcohol or an aqueous alcohol or distilling it; and (4) an antiradical containing these three types of crude rapeseed oil extracts.
