【摘要】 研究了60Co-γ射线辐照稻米(糯米、粳米、籼米)对其蛋白质、直链淀粉、总淀粉、淀粉粘度谱、胶稠度的影响。结果表明,经0.5～7kGy剂量辐照处理的稻米,淀粉含量、胶稠度随辐照剂量的增加而显著降低,淀粉粘度谱的最高粘度、热浆粘度、冷胶粘度也随辐照剂量的增加明显下降。实验得出稻米辐照杀虫剂量应控制在3kGy以下为宜。更多还原

【Abstract】 Effects of 60Co γ-rays irradiation on protein,amylase,total amylum,amylum viscosity chart,gel con-sistancy of rice (glutinous rice,japonica rice and early indica rice) were studied. The results indicate that after the ir-radiation treatment by the dosage of 0.5～7 kGy irradition,the contents of amylum,gel consistency obviously de-crease with increment of the irradiation dose. And the peak paste,hot paste and cool paste of amylum viscosity chart also decrease with increment of the irradiation dose. The results show that the irradiation dose for eliminating pests of rice should be controlled under 3 kGy.更多还原
