摘要：

In the thiobarbituric acid (TBA) assay of oxidized oils, the development of red 2:1 TBA -malonaldehyde adduct was enhanced by ferric and ferrous ions and suppressed by EDTA in a dose-dependent manner. The effect of the ions could not be ascribed to the increased release of malonaldehyde from the oils, but was reasonably ascribable to the increased TBA-reactivity of alkadienals and/or alkenals released from the oils, since the reactivity of these aldehydes was quite similarly enhanced by the ions and suppressed by EDTA. The development of the adduct from the oils, alkadienals and alkenals was suppressed by cupric ion, probably owing to its activity to destroy the adduct. These findings strongly support the idea that alkadienals and/or alkenals are the major TBA-reactive substances in the oxidized oils.
