In the comparison of the antioxidative activity of melanoidin on linoleic acid with that of each tocopherol homologue, melanoidin exihibited more inhibitory effect on the oxidation of linoleic acid than dl-α-, dl-β-, d-γ- and d-δ-tocopherol. The synergistic effect of melanoidin was observed on dl-β-, d-γ or d-δ-tocopherol, but not dl-α-tocopherol. The antioxidative activity of melanoidin on copper-containing linoleic acid was multiplied by adding citric acid, but this synergistic effect was not observed in the linoleic acid without containing copper.
In the combination of two kinds of antioxidants selected from melanoidin, tocopherol and citric acid, melanoidin and tocopherol showed the most effective inhibition on the oxidation of linoleic acid under the presence of copper. However, the combination of melanoidin, tocopherol and citric acid showed more antioxidative activity than that of melanoidin and tocopherol.
