日前,日本大阪的一位71岁老人井川重信开发出一种新型牛奶杀菌技术,即利用高电场中存在很大电位的原理来实现杀灭细菌的目的。这项技术的原理是把含有细菌的液体通过一个电位差很大的高电场,这样细菌的细胞膜内外的电压就有很大差异,电压差使细胞膜破裂从而杀死细菌。为了验证这个想法,井川让含有大肠杆菌的水通过由普通电容器改装成的、能产生2000伏特电压的电极之间,结果大肠杆菌全部被杀死了。但2000伏的高压在安全性和实用性方面有很大的隐患,而且在成本上也需
Recently, a 71-year-old from Osaka, Japan, Ichikawa reborn to develop a new type of milk sterilization technology, that is, the use of high electric field exists in the principle of high potential to kill bacteria. The principle of this technique is to pass a liquid containing bacteria through a high electric field with a large potential difference, so that the voltage difference between the inside and outside of the bacterial cell membrane is very different. The voltage difference breaks the cell membrane and kills the bacteria. To test this idea, Ichikawa made E. coli-containing water pass between electrodes modified to 2,000 volts from a common capacitor, with the result that all of the E. coli were killed. However, the high voltage of 2000 volts has great hidden dangers in terms of safety and practicability, and the cost is also required
