Effects of pulsed microwave on fatality rate of rice weevil and Aspergillus parasiticus and rice quality (rice temperature,the ratio of broken-rice and cracked-rice,and sensory quality) were investigated to provide a suitable microwave processing technology for rice storage.Based on the single factor experiments of width,dose,total time and intermittent time of microwave,the fatality rate of rice weevil and Aspergillus parasiticus increased dramatically with the increase of irradiation intensity.Meanwhile,the rice temperature increased gradually,weevil hatchability declined dramatically,the ratio of broken-rice and cracked-rice increased slightly with no obvious changes in overall sensory.By orthogonal test,the optimal pulsed microwave condition was found to be pulsed microwave dose of 7.5 W/g,pulse width of 300 ms,interval time of 50 ms,the total processing time of 30 s.Under the optimal condition,the fatality rate of rice weevil and Aspergillus parasiticus was 100.0% and 83.2%,respectively.The rice temperature was 53.8℃.The ratio of broken-rice and cracked-rice increased by 1.2% and 1.5%,respectively.The sensory score was 7.3.
