Lillian+Blouin+Pasteurization

**Louis Pasteur (1822-1895)** Louis Pasteur's discovery in 1856 led to a revolution of the world of medicine and nutrition, when he was commissioned to determine what was causing beet root alcohol to sour. It was believed, during this time, that fermentation was a chemical process, however his research led him to realize that it was in fact yeast that was turning the substance. This led to what is now known as a germ and his germ theory of fermentation. He was then commissioned to "save" France's wine by Emperor Napoleon III from "the diseases of wine". He realized that heating the fermented wine would kill the microbes that caused it to spoil. He researched how long it would take and at what temperate it would kill the harmful microorganisms, all without changing the taste of the wine. This discovery was then used on beer and vinegar, and was patented and called pasteurization. During this time, tuberculosis was commonly carried by milk until the pasteurization of milk in the late 1800s. Tuberculosis is a bacterial infection that can spread through the lymph nodes and bloodstream to any organ in your body. Pasteurization was first developed to kill the tuberculosis pathogen and was successful as the number of tuberculosis cases contracted from milk fell dramatically. Pasteurization led to the lowering of the products prices as it was kept longer and more of it could be produced. Pasteurization was incredibly helpful as not only did it lower prices, but it lowered the number of dairy borne diseases and increased wellness in general. His knowledge of these microorganisms eventually lead to develop the germ theory of disease and vaccines for rabies, chicken cholera and anthrax, which ultimately saved countless lives.
 * I had no idea pasteurization had an impact on medicine and that Tuberculosis was even spread through milk!

Hey Lilly! Sorry for writing on your really nice Wiki! I really like how you have lot of information in one readable and interesting paragraph. Your explanation of the process of Pasteurization came to be is really interesting. I didn't know that this had an effect on how much milk could cost. Now I do, and thank you for that. Ollie Sughrue
