摘 要:
研究了果汁厚度、辐射距离、辐射时间和杀菌温度4个因素对紫外线杀灭接种在梨清汁中的大肠杆菌的影响。并通过正交实验得出各因素的最佳组合。结果表明：辐射时间和果汁厚度对紫外线的杀菌效果影响最为显著。当果汁厚度为0.5 mm,辐射时间为5 min,辐射距离为10 cm,杀菌温度为30℃时,杀菌率可达99.95%。[著者文摘]

Abstract:
The inactivation of thickness,irradiating distance,irradiating time by Ultraviolet（UV） and prepared temperature on E.coli in pear juice was studied.It has been found that the optimum condition were as the following：irradiating time and thickness were more important than other factors,the inactivation can be 99.95 % when the thickness was 0.5 mm,irradiating time was 5 min,irradiating distance was 10 cm,and prepared temperature was 30 ℃.[著者文摘]
