Pasteurized milk is milk which has been heat-treated to kill pathogens which cause disease. Not all pathogens are removed during the pasteurization process, so pasteurized milk is not 100% sterile, but many people consider it to be safer to drink than raw milk which has not been pasteurized at all. The bulk of the milk sold in commercial grocery stores is pasteurized.
Sterilized milk is Milk which heated to 120°C for a few minutes or to just over 100°C for 20 to 30 minutes and aseptically sealed in a narrow necked bottle with a crown cork. This process kills all pathogenic and most other microorganisms and spores and the milk will keep for 1 to 2 years. The milk is off white in colour and has a characteristic caramel, boiled milk taste which is not to everyone's liking.
the difference is that the canning process is just to preserve the food inside a can, but the pasteurization process is to kill the bacteria found in wine and milk that can cause bacterial diseases and to preserve the wine and milk.
Pasteurization is a FORM of sterilization, however pasteurization uses a brief period of heating only while sterilization can use many other methods to kill microorganisms (e.g. toxic chemicals, burning, ultraviolet light, x-rays, gamma rays). With pasteurization used on food products they will be edible (although with some foods the flavor will slightly deteriorate, e.g. cooked flavor) while with some forms of sterilization their use on food would be unacceptable.
The pasteurization does not kill the spore forming microbes, only inactivates the living cells.
He didn't invent milk, he just pasteurized it.

A large proportion cheeses are pasteurised. Some cheeses like Cheddar you can get in both pasteurised and unpasteurised form.
When something is pasteurized, it means it has been heated to a high enough temperature to kill the dangerous bacteria in it. One food product that is well-known for being pasteurized is milk.
Milk is not a chemical compound it is amixture of many compounds. Pasteurisation is a process that heats milk to kill bacteria without affecting the properties of the milk too much.
Sanitizing generally involves removing the contaminants that would grow bacteria while sterilizing involves killing the bacteria. Food can be sterilized such as when milk is Pasteurized.
Goats milk for human use has been pasteurized and tested to insure that it doesn't have any harmful bacteria in it.
You are talking about 2 different things. Whole milk is milk that has not been "skimmed" or had its milk fat removed. Whole milk contains about 4% milk fat, while reduced-fat milk varieties may contain 1 or 2% milk fat. Skim milk has no milk fat left, and is also called "fat free" milk. Pasteurization is the sterilization process by which foods, including milk, are treated in order to kill pathogens which can cause disease. Any variety of milk may be pasteurized. In fact, whole, 2%, 1% or skim pasteurized milk are widely available in most grocery stores in the United States and Canada.
Any milk has to be pasteurized if it is going to be sold on retail market. So yes, whole milk has been pasteurized. However. Pasteurization and the wholeness of milk are not directly related. Pasteurization is a heating process used to kill harmful germs found in milk. Whole milk is milk from which the cream has not been skimmed off- it may or may not have been pasteurized.
Yes, all milk that you purchase from stores are pasteurized.
Raw milk, or, milk that has not been pasteurized.
Milk can be unsafe for humans to drink as it can make them sick. Therefore, milk is pasteurized so that it is safe and healthy for human consumption.
Milk that has been pasteurized is what is referred as the healthy milk.
