The present study was carried out to examine the antioxidative actions between the products of amino-carbonyl reaction and commercial antioxidants, and investigate their synergistic effects. Nondialyzable melanoidins exhibited more significantly in the antioxidative action than unfractionated meanoidins did. Also, in the case of unfractionated melanoidins, both glycine and histidine were more effective than aspartic acid for the antioxidative action. There was no significant difference among amino acids in the action of nondialyzable melanoidins. The unfractionated melanoidin was not as good as antioxidative action of the synthetic antioxidants, butylated hydroxytoluene, tert-butyl hydroquinone and ascorbic acid ; however, the one was superior to that of natural antioxidants, ${\alpha}$-tocopherol and lecithin. Otherwise, the action of nondialyzable melanoidin was similar to that of synthetic antioxidant. The synergistic effects were increased in using melanoidin with ${\alpha}$-tocopherol and lecithin except for the systems of fructose-aspartic acid and fructose-glycine in unfractionated melanoidins.
