Guest guest Posted October 22, 2007 Report Share Posted October 22, 2007 Milk is first pasteurized, i.e. heated to remove bacteria, etc., then it's homogenized. I think the best milk to buy is organic raw milk. You can buy it at the market in some states - California and Illinois, I think Iowa too. Otherwise, establish a relationship with a local farmer to get fresh milk. You usually have to own the cow. And who wouldn't want to have their a cow! The processed stuff shouldn't even be called milk. This is from Wikipedia... Pasteurisation typically uses temperatures below boiling since at temperatures above the boiling point for milk casein micelles will irreversibly aggregate (or " curdle " ). There are two main types of pasteurisation used today: high temperature/short time (HTST) and ultra-high temperature (UHT, Also known as Ultra-heat treated). In the HTST process, milk is forced between metal plates or through pipes heated on the outside by hot water, and is heated to 71.7 °C (161 °F) for 15-20 seconds. UHT processing holds the milk at a temperature of 138 °C (250 °F) for a fraction of a second. Milk simply labeled " pasteurized " is usually treated with the HTST method, whereas milk labeled " ultra-pasteurized " or simply " UHT " must be treated with the UHT method. HTST pasteurized milk typically has a refrigerated shelf life of two to three weeks, whereas ultra pasteurized milk can last much longer when refrigerated, sometimes two to three months. When UHT pasteurization is combined with sterile handling and container technology, it can even be stored unrefrigerated for long periods of time. One of the oldest applications of homogenization is in milk processing, where the aim is to prevent or delay the natural separation of cream from the rest of the emulsion. The fat in milk normally separates from the water and collects at the top. Homogenization is the process of breaking up that fat into smaller sizes so that it no longer separates from the milk, allowing the sale of non-separating 2% and whole milk. This is accomplished by forcing the milk at high pressure through small orifices.
