摘要
采用单片机控制技术，研制出了自动控制脉冲强光杀菌装置．该装置每个光脉冲的输入能量可达１２００Ｊ，光脉冲宽度小于８００μｓ．４０个光脉冲能使霉菌减少４个数量级，使α－淀粉酶的活力钝化７０．５％，且脉冲强光杀菌未对维生素Ｃ造成显著的破坏作用．
Automatic controlled sterilizing equipment with pulsed light by using single_chip computer is developed. The input energy of a light pulse is up to 1 200 Joule. The pulse time is less than 800 microseconds. 40 pulsed light flashs can kill mold from 10 4/ml to 0. The activity of α_amylase passivates by 70.5% with 40 pulsed light flashs. Pulsed light does not casue harmful effect on vitamin C.
