Pasteurization

In 1862, the first test of pasteurization was completed by Louis Pasteur and Claude Bernard. Jars, sealed since 3 Mar, were opened at a meeting of the French Academy of Sciences. They containing dog's blood and urine that had been maintained at an elevated temperature of 30ºC. Neither liquid showed observable decay or fermentation. This suggested the possibility of heating foods sufficiently to kill germs without significantly altering their chemical composition. Pasteurization was applied by brewers. By heating the finished beer to above 160ºF, to kill harmful bacteria, a germ-free beer could be produced which did not require constant refrigeration for lengthy shipment or storage. It also came to be used for milk and other products.
