Abstract： In this paper, the changes of rice-starch’s viscosity at different dose irradiation treatment were studied, the rice can be easily distinguished whether it has been irradiated or not with the control of pH. The results showed that the starch’s viscosity was significantly declined with increasing irradiation absorb dose. With the control of pH 2.5, the irradiated starch’s viscosity was apparently higher than the un-irradiated ones, there are significant differences in terms of viscosity between the two parts. The rice absorbed dose can be estimated using the relationship among peak viscosity, hot pasting viscosity and absorbed dose.

Abstract： The ESR signal of black sesame, soybean, peanut irradiated with 0‒9 kGy absorbed dose was determined and the characteristics and intensity were different. The relationship between signal intensity and absorbed doses was also investigated .The results showed that the ESR spectra of irradiated samples inhibited obvious variation compared to those un-irradiated. The dose-response curves of the samples exposed to gamma rays could be described well by binomial function. Besides, the ESR signal intensity was related to the species of samples. This study may be a method for detection of irradiated oilseed by ESR.
