真空杀虫与抑制霉菌的初步研究

Preliminary Study on Vacuum Insecticidal and Inhibiting Mould

以米蛾幼虫和青霉为研究对象,进行真空杀虫与抑制霉菌的初步实验研究。通过真空压力和处理时间对粮食害虫致死率和抑制霉菌生长的影响分析,得出杀虫的最佳真空压力和抑制霉菌生长的最佳真空处理时间。结果表明,随着真空压力的降低和处理时间的增加,真空对粮食杀虫和抑制霉菌的效果会随之增加。真空杀虫达到最佳效果的真空压力在900Pa到1300Pa压力段内,真空抑制霉菌处理时间持续330min以上,可以确保98%的致死率。

The preliminary experimental study on the vacuum insecticidal and inhibition of mould was carried out by using the rice moth larvae and penicillium. Analysis of the effects of vacuum pressure and treatment time on the mortality and the inhibition of the growth of the grain pest, the optimal vacuum pressure and treatment time of the inhibition of the growth of molds were obtained. The results showed that with the decrease of vacuum pressure and increase of processing time, vacuum insecticidal and inhibit mold effect on food will increase. Vacuum Insecticide achieve the best results of vacuum pressure is within 900 Pa to 1300 Pa pressure segment, and processing time of inhibit mold continued 330 minutes or more, which can ensure 98% mortality rate.
