Casein (/ ˈ k eɪ s iː n / KAY-seen, from Latin caseus "cheese") is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. [1]
A glass of soured milk whey. Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacturing of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese.
Modified milk ingredients also called natural milk constituents are umbrella terms for a group of milk products which have an altered chemical state from that which is naturally found in milk. This includes casein, caseinates, whey products (including whey butter and whey cream), cultured milk products (including yogurt, sour cream and cultured ...
Casein molecule. Calcium caseinate is one of several milk proteins derived from casein in skim and 1% milk. Calcium caseinate has a papery, sweet and overall bland flavor, and is primarily used in meal preparation and fat breakdown. [1] Caseinates are produced by adding an alkali to another derivative of casein
Native whey protein is extracted from skim milk, rather than being collected as a byproduct of cheese production. This type of whey does not contain glycomacropeptide, which is formed only after the addition of rennet. [15] [16] [17] There is evidence that whey protein is more bio-available than casein or soy protein. [18] [19]
MPC contains micellar casein, whey proteins, and bioactive proteins in the same ratio found in milk. As the protein content of MPC increases, the lactose levels decrease. This high-protein low-lactose ratio makes MPC an appealing ingredient for protein-fortified beverages and foods and low-carbohydrate foods.
GMP is unique from other milk peptides in several ways. Kappa-casein is the only glycosylated casein protein and GMP, which makes up much of Kappa-casein, is also glycosylated. The glycans make GMP the only portion of the casein micelle that is water soluble after curdling has occurred, and thus, the only fraction of casein protein to dissolve ...
FTC-κ-casein allows the detection of different types of proteases at levels when no milk clotting is yet apparent, demonstrating its higher sensitivity over currently used assay procedures. Therefore, the method may find application as an indicator during the purification or characterization of new milk-clotting enzymes.
