Ultrafiltered milk
Encyclopedia
Ultrafiltered milk is a subclassification of milk protein concentrate
that is produced by passing milk under pressure through a thin, porous membrane to separate the components of milk according to their size, permitting greater efficiency in cheese making. Specifically, ultra filtration allows the smaller lactose, water, mineral, and vitamin molecules to pass through the membrane, while the larger protein and fat molecule (key components for making cheese) are retained and concentrated. (Depending on the intended use of the UF milk product, the fat in whole milk may be removed before filtration.) The removal of water and lactose reduces the volume of milk, and thereby lowers its
transportation and storage costs. Ultrafiltration
makes cheese manufacturing more efficient and can benefit consumers if cost savings are passed on. However, U.S. milk producers are concerned that imported UF milk may displace domestically produced milk used to make cheese.
In 2008, HP Hood
and Tuscan Dairy Farms
began to sell UF milk by the half-gallon as Hood Simply Smart or (Tuscan) Over the Moon. It is marketed as skim milk that tastes just like 2%.
Milk protein concentrate

Ultrafiltration
Ultrafiltration is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane...
