The skim milk is then fractionated using ultrafiltration to make a skim concentrate that is lactose-reduced. [1] This process separates milk components according to their molecular size. Milk then passes through a membrane that allows some of the lactose, minerals, and water to cross through.
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digest solid food. [1] Milk contains many nutrients, including calcium and protein, as well as lactose and saturated fat. [2]
Separated from milk through the process of fractionation, it is a functional compound [2] and consists of several milk proteins which are biologically active. The composition is approximately 54% lactoferrin and 41% lactoperoxidase , [ 3 ] with other active proteins, such as Cyastin C and high mobility group-like proteins, making up the ...
Milk equivalent is a measure of the quantity of fluid milk used in a processed dairy product. Measured on a milkfat basis, it takes about 21.8 pounds of farm milk to make a pound of butter, and about 9.2 pounds to make a pound of American cheese .
Milk is usually sold in half-pints (8 fluid ounces), pints, quarts, half gallons, and gallons. Water volume for sinks, bathtubs, ponds, swimming pools, etc., is usually stated in gallons or cubic feet.
In fact, a gallon of 2% has more than half the fat as a gallon of whole milk. The FDA requires whole milk to have at least 3.25$ fat by weight. But the amount of fat can range from 3.25$ to 5 ...
This makes the milk coagulate or curdle, separating the milk solids (curds) from the liquid whey. [4] Sweet whey is the byproduct of rennet-coagulated cheese, and acid whey (also called sour whey) is the byproduct of acid-coagulated cheese. [5] Sweet whey has a pH greater than or equal to 5.6; acid whey has a pH less than or equal to 5.1. [6]
Ultrafiltered milk, also known as UF milk, UF skim, or diafiltered 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 size. [1] [2] Specifically, ultrafiltration allows the smaller lactose, water, mineral, and ...
