The antioxidative ability of inosine 5'-monophosphate (IMP) and guanosine 5'-monophosphate (GMP) at various water activities (A_w, 0〜0.75) and at 40℃ was investigated. IMP and GMP exhibited antioxidative ability above A_w 0.25, and this ability was strongest at A_w 0.5. There was no obvious difference between the ability of IMP and GMP. IMP-related substances (hypoxanthine, inosine and ribose 5-phosphate) did not have antioxidative ability, suggesting that both the base and phosphate moieties of 5'-ribonucleotide are necessary to exhibit this ability. The ability of IMP and GMP was weaker than of 2,6-di-tert-butyl-4-methylphenol (tert-butyl-hydroxytoluene ; BHT) and ethylenediamine tetraacetic acid (EDTA). The possible mechanism for the antioxidative ability of IMP and GMP was assumed to be their chelating action.
