About Whey powder

Whey powder is a dried dairy ingredient made from whey, the liquid separated from milk during cheesemaking or related dairy processing. Its composition and flavour vary with the source whey and how it is processed; it is not the same as whey protein isolate.

It is sold as a free-flowing powder, usually pale cream to yellowish, with a mildly dairy, sometimes sweet or tangy flavour. It is used in baking, confectionery, and formulated foods, where it can contribute dairy flavour and solids. Products may be sweet-whey or acid-whey powders, and these forms should not be treated as interchangeable.
