Why protein is manufactured from milk

Why protein is manufactured from milk. Manufacturers use various processing methods to separate WHEY PROTEIN from fat, lactose and other components found in milk. Some of the common methoths are listed below. These terms often show up on the product labels. Here's what they means:

* ULTRAFILTRATION:

A process that uses pressure and a porous membrane to separ...ate the fat and lactose from milk.



* MICROFILTRATION (MF) or CROSS-FLOW MICROFILTRATION (CFM):

A method that further separates whey protein from fat and lactose through a low-temperature process using high-tech ceramic filters that maintain the majority of the beneficial fractions. MF- and CFM-type processing removes the large fat globules that ultrafiltration cannot separate to achieve a fat content of less than 1%.

* ION EXCHANGE (IE)

A method that uses ionically charged resins and chemicals such as hydrochloric acid and sodium hydroxide to separate protein. This process is often used to produce the purest form of whey protein isolate--meaning it has the highest protein content of all whey proteins (90% or more). The drawback is that some of the beneficial subfractions are lost, particularly hunger-suppressing glycomacropeptide.

* HYDROLYSIS

Describes the separation of protein into peptides (multiple amino-acid fragments). Hydrolysis breaks some of the amino-acid bonds in the protein chain, allowing the protein to be digested and absorbed more rapidly.
