Caseins are a manufactured dairy product by drying a curd to a powder. Casein production takes place by curdling and straining, when rennet (leading to rennet casein) or an edible acidic (leading to acid casein) substance is added. The curd is dried, usually on a roller dryer or extruder to casein powder. Caseinate is modified acid casein by reacting with a hydroxide like sodium or calcium hydroxide, it has perfect emulsifying capabilities.

Milk Protein Powder is a concentrate of skim milk that is obtained by using ultra filtration to make lactose reduced skim concentrate. This concentrate is concentrated further by evaporation followed by spray drying into a powder. Milk protein concentrate, also known as MPC is available in 40-90% milk protein.

Whey proteins make up approximately 20% of the proteins in milk and stay suspended in the whey during cheese or casein production. Whey Protein Powder is a concentrate of whey that is obtained by using ultra filtration to make lactose reduced whey concentrate. This concentrate is concentrated further by evaporation followed by spray drying into a powder. Whey protein concentrate, also known as WPC is available with 40-90% whey proteins.

Various kinds of proteins have many different applications, for example in sports nutrition, cheese, yogurt, energy bars, drinks and meat to name a few. Proteins are also used as a functional ingredient to stabilize emulsions and for the manufacturing of fat filleds, toppings and foamers.
