摘要：The interaction between antioxidants is affected by many factors, such as concentration, ratio and system. In this study, different concentrations of α-tocopherol and γ-oryzanol showed antagonistic effect in the oil-in-water emulsion, and the distribution of α-tocopherol increased in aqueous phase after combined with γ-oryzanol. The concentration could affect the degree of antagonism. According to fluorescence quenching, cyclic voltammetry measurements and the oxidative decomposition of antioxidants during storage, the inhibitory effect of γ-oryzanol on the regeneration of α-tocopherol was proposed to be responsible for the antagonism. This work can provide suggestions for studying the mechanism of antioxidant interaction in emulsion system.
