The inhibitory ratio E for these two kinds of radicals is in proportion to the concentration of chitosan. It was also observed that E for linoleic acid lipid radicals increased with the increase of the degree of deacetylation and decreased with the increase of the molecular weight of chitosan. %K chitosan %K antioxidant %K oxygen free radical %K lipid free radical %K linoleic acid %U http://link.springer.com/article/10.1360/02tb9198
