Pasteurization of foods and beverages is a physical change.
Pasteurization process was invented by Louis Pasteur in 1864. He applied that to beer and wine.
Pasteurization is a process to which foods and beverages are subjected to before vacuum packing. The process involves killing of the bacteria and microbes which cause fermentation of the food and beverages. The number of such pathogens is reduced. So food stays longer at a higher quality.
The food items are not altered. Perhaps some preservatives are added. But the items are not changed in their chemical composition. There is no chemical reaction. Milk and milk products, all canned products, fruit juices, beverages are pasteurized. UHT milk can be stored in refrigerator for even 6 months.
