| Research Abstract |
Antioxidant activity and the structure of high-active ingredients in commercial cheeses were studied for development of functional cheese which can decrease oxidative stress. Antioxdant activities were observed in most of ripened cheeses, except of non-ripened cheeses. High activity was especially observed in Blue, Stilton, Epoisses, Pont-l' Eveque, Camembert and Brie cheese. The antioxidant ingredients were purified and isolated from the Blue cheese, and the structure of them was clarified. Consequently, the antioxidant peptides and also the polyphenols such as the homogentisic acid and the homoprotocatechuic acid were identified from the Blue cheese.
