摘要
针对高压气体(CO2、N2)“渗透破碎”杀灭液体中细菌的机理,采用正交方法,综合考虑杀菌时间、溶液浓度、作用压力和杀菌媒质等不同因素作为评价指标进行试验研究.结果表明:通过使用2种不同杀菌媒质所得结果的比较,进一步验证高压气体的“破碎”杀菌机理;CO2的“酸化效应”对杀菌效果的影响不大;杀菌率会随时间、压力、浓度的增加而增大.
In order to study the principle of liquid sterilization by high - pressure gas, the Orthogonal experiment based on the value index of time, pressure, solution concentration and sterilizing medium was conducted. The experimental resuits confirm the rupture mechanism by comparing the rate of inactivation among the different medium. The dissolved CO2 ＇s acidity has no influence on the rate of sterilization. It also show that the rate of sterilization will increase when time, solution concentration and pressure raise.
