Open publisher page 0 citations

Abstract

In this article, polyphenols in apple pomace were tested for their radical-scavenging by measuring their capacity to scavenge superoxide anion radicals generated by a pyrogallol autoxidation system, hydroxyl radicals generated by Fenton reaction and nitrite. The result indicated that the inhibition percentage of polyphenols against O·2,· OH and NO2-reached-97.56%, 95.65% and 76.98% respectively. The polyphenols in apple pomace were good oxidant inhibitor with strong free-radical-scavenginga ction.
