When Did Louis Pasteur Discovered Pasteurization?

In 1863, at the request of the emperor of France, Napoleon III, Pasteur studied wine contamination and showed it to be caused by microbes. To prevent contamination, Pasteur used a simple procedure: he heated the wine to 50–60 °C (120–140 °F), a process now known universally as pasteurization.

When was pasteurization discovered?

Raw milk refers to non-pasteurized. Pasteurization is the name of the process discovered in part by the French microbiologist Louis Pasteur. This process was first used in 1862 and involves heating milk to a particular temperature for a set amount of time in order to remove microorganisms.

When did Louis Pasteur develop pasteurization?

Pasteur completed the first successful test on April 20, 1862, eventually patenting the method we now know as pasteurization, which was soon applied to beer, juice, eggs, and (most famously) milk. This process also proved successful at destroying most yeasts and molds without causing a phase transition in the product.
