The rice bran was stored in different temperature. The effect of different storage temperatures on acid value(AV)and peroxide value(POV) of rice bran was discussed. The relationship between temperature and storage life was set based on the temperature-AV/POV first order chemical reaction kinetics model to predict the storage life of rice bran under different storage temperature.The result showed: there was a logarithmic relationship between the storage life (t) of rice bran and storage temperature (T), the relation is: lnt=-0.031 3 T+4.959 2, the storage life can be calculated by substituting different temperature based on the relation.
