Who discovered pasteurization?
This is a biology question. Louis Pasteur discovered that heating the food (high temperature) inside a closed frask, the bacteria is killed and the food can be conserved a long time. this process is then called pasteurization. All the food cans, and the UHT milk can be conserved at room temperature for months or years, as all the bacteria is killed. In the traditional milk and juice, the pasteurization destroy near all the bacteria, and refrigeration is needed to conserve the food.
