Louis Pasteur,the famous French chemist and bacteriologist,invented “pasteurization”.In 1854 Pasteur was made head of the department of science at the University of Lille,and it was there that he made one of his most famous discoveries.Lille was a major center for wine and beer-making,and some of the local wine-makers asked Pasteur if he could help solve the problem of keeping wine fresh.At that time,it was believed that food and drinks go “bad” due to a purely chemical process (变化过程).But during a series of experiments Pasteur proved that tiny living organisms caused food and drinks to go bad.In the case of wine and beer the organisms are already present in the form of the various yeasts (酵母) that caused the fermentation (发酵) process.Pasteur discovered that heating the wine gently for a few minutes after it had fermented would kill off the yeast that was left in the wine,with the result that the wine would remain fresh for much longer.He also proved that food and drinks could be turned bad by other organisms that were present in the air,and that they too would keep fresh much longer if they were kept in airtight containers.
The heating process was so successful that it made Pasteur famous.It was named “pasteurization” in his honour,and by about 1900 it had been widely used for processing and bottling cows’ milk.The result was a huge drop in the number of bottle-fed babies dying from infant diarrhea (婴儿腹泻) and from that time on it has been a standard treatment for milk and many other food products.This simple process has saved thousands,possibly millions,of lives worldwide.

法国著名的化学家、细菌学家——路易斯·巴斯德发明了“巴氏灭菌法”.1854年,巴斯德在里尔大学科学系名列前茅,也正是在那里他做出了他最有名的发现之一.里尔是制作白酒和啤酒的主要城市,当时一些当地的白酒生产者请求巴斯德给予他们帮助,让他想办法帮他们解决让白酒保鲜的问题.在当时,大家都认为食物和饮料都会逐渐变“坏”是一个纯粹的化学变化过程,但是在一系列的实验之后,巴斯德证实是微生物致使食物和饮料变坏的.在白酒和啤酒当中,微生物已经以引起发酵过程的各种各样的酵母形式存在了.他发现在白酒发酵之后将白酒微微地加热几分钟就会将那些存留在白酒中的酵母杀死,如此这样后白酒将会更长时间的保持新鲜.同时他也证实了由于空气中一些微生物的存在食物和饮料也会变坏,但是如果将他们装在密闭的容器中他们也会更长时间的保持新鲜.这个加热过程使得巴斯德变得有名起来,为了纪念他它被命名为“巴氏灭菌法”,到大约1900年该法已被广泛应用于加工瓶装牛奶的生产上了.而最终的成果是靠牛奶养育的婴儿死于婴儿腹泻的数目的大大减少,也是从那时起,该法被当作牛奶和许多其他食物产品的标准制法.这一简单过程拯救了世界上成千上万或者说百万的生命!
