How Whey Powder is Made?
Whey protein is Separated from casein Protein of Milk when the Milk is Made in to cheese or when Rennet / Acid casein is made.
The Whole Milk will have Fat along with Solid Not Fat (SNF) and water. This SNF has Protein, Lactose (Carbohydrates) and Minerals. Milk Contains 2 Major Proteins viz., Casein (80%) and Whey (20%).
When Making Cheese, The fat Along with the Valuable casein Proteins are Denatured and coagulated by Cheese Making Bacteria and the Whey Proteins along with Lactose Gets Separated as whey water.
When Making Casein, De Fatted Skimmed Milk is used for the process. The Valuable Casein Proteins are Denatured and coagulated by Rennet or Mineral Acid and the Whey Proteins along with Lactose Gets Separated as whey water.
The Whey Water is then De mineralized (Removal of Minerals by Nano Filtration) and Evaporating in Vacuum followed by Spray drying to get Whey Powder.
There are Several Kinds of whey powder and Here we represent the Sweet Whey Powder from Cheese process. Whey Proteins normally has a bland taste hence for palatability, it is Flavored in Direct Consumption Applications.
