Demineralized whey powder

What is demineralized whey powder

Demineralized whey powder is a great source of profit and supplementary nutrition. It is a very beneficial ingredient used in many foods and dairy products.

Demineralized whey powder is the final product after the electrodialysis (ED) and spray-drying process. Electrodialysis extracts minerals from the liquid whey utilizing the membrane process. Then the demineralized liquid whey is spray-dried (liquid removal) into demineralized whey powder.

Typical levels of demineralization are D40, D50, D70, D90 (1% ash ODB).

Use of demineralized whey powder

Nowadays, whey and its derivatives such as whey protein concentrate (WPC), and whey protein isolate (WPI) are highly valued by-products of dairy (curd, Greek yogurt, casein) and cheese manufacturing industries. They have a high potential for their nutritional value and various options for further processing/reuse, in terms mainly of their content of protein, eventually lactose.

Demineralized whey powders are a cost-effective and tasty alternative for skimmed milk solids in numerous applications:

infant formula,
sports nutrition,
baby food,
bakery, sauces,
dietary foods,
chocolate, confectionery, ice cream,
cheese,
fortified dairy products,
and animal feed.
