摘　　要：采用单片机控制技术，研制了自动控制脉冲强度杀菌装置。每个光脉冲的输入能量可达６００～２２００Ｊ；光脉冲宽度经测定小于８００μＳ。３０个光脉冲能使大肠杆菌减少５个数量级，４０个光脉冲以使蛋白酶的活力钝化９０％，脉冲强光杀菌可事负透明塑料薄膜包装的切片面包的保存期延长１倍以上，脉冲强光杀菌是一种很有发展前途的冷杀菌技术。Automatic controlled sterilizing equipment with pulsed light using single-chip computer was developed. The input energy of a light pulse was 600 to 2200 joule. The pulse time was less than 800 microseconds. 30 pulsed light flashs could kill bacillus subtilis from 105/ml to 0. The activity of protein enzyme de-cresed 90. 3 with 40 pulsed light flashs. Pulsed light could extend the shelf life of bread sealed by transparent film 2 times.
