Got milk? We often hear this thru commercials and became a trending meme.
It is somehow confusing if you go to the supermarket and look for milk, you would find different milk types but just sounds the same, especially their nutrition label. The most common milk that we have is the UHT (Ultra-high temperature processing) and the Fresh milk.
UHT milk is heated to a temperature higher than 275°F for more than two seconds. This is the milk you find in aseptic (cardboard) containers and non-refrigerated shelf. If not opened, has a typical unrefrigerated shelf life of six to nine months.
Fresh milk has not been pasteurized, a process of heating liquid foods to decontaminate them for safe drinking. When milk is fresh it always need to stay refrigerated. When it is not cooled it will go off. That is how you recognirze the difference between fresh and UHT milk. Is the milk on selling stored in a ref or is it stored on the shelf?
Proponents of raw milk have stated that there are benefits to its consumption, including better flavor, better nutrition, and the building of a healthy immune system, the medical community has warned of the dangers, which include a risk of infection.
Since UHT milk doesn't require refrigeration during shipping or on the supermarket shelf, it may be better for the environment. Nutritionally, UHT milk is slightly poorer than fresh milk; it contains around a third less iodine, and the quality of protein degrades during storage.
Pasteurization is intended to make milk safer and government agencies claim it doesn't reduce nutritional value.
