Well, that’s what we want to know and investigate the matter in order to share these things are so common place, but we do not know. The original milk obtained at the bottom of the cow “or the appropriate animal, has a high content of milk components, such as water, fat, protein and a number of bacteria and chemicals that may damage the body, which is why, for distribution in the population undergoes pasteurization.

Pasteurization is nothing less than the process of eliminating germs and bacteria in a food product, in this case milk, through heating to high temperatures in liquid product. With this system uses only the “good” milk, eliminating what does not.

The process takes place at a temperature of 60-75 ? C for about 30 minutes. There is also the “ultra pasteurization” that is the same process, but at a higher temperature of about 135-150 ? C and at a time of 2 to 8 seconds. The difference between these systems is that only pasteurized milk destroys the bacteria, so it is necessary to keep it refrigerated and has a duration of up to 5 days after opening the package.

Instead ultrapasteurized milk is sterilized in its entirety, so it lasts much longer. In any case with both types of milk has the same beneficial characteristics. In professional terms, it is called “raw milk” to one that has come straight from the cow, sheep or goat that has not been heated to a temperature above 40 ? C or subjected to treatment having equivalent effect.

Now the name comes from Louis Pasteur, French chemist who lived in the 19th century. Pasteur discovered that microorganisms were affecting the composition of wine, so he had the bright idea to submit it to a temperature of about 44 ? C for a short time, avoiding the degradation of this product.

There began the pasteurization and went down in history for that. This process also occurs with other foodstuffs such as ice cream.

So when you drink milk, make sure it is pasteurized, to avoid potential health problems.
