Demineralized Whey

Demineralized wheyProduct Definition

Demineralized whey (also called reduced-minerals whey) is obtained by removing a portion of the minerals from pasteurized whey. Typical levels of demineralization are 25%, 50% and 90%. The dry product may not exceed 7% ash. Demineralized whey is produced by physical separation techniques such as precipitation, filtration or dialysis. The acidity of demineralized whey may be adjusted by the addition of safe and suitable pH ingredients.

Typical Applications

For dairy, bakery, confectionery, and other food and nutritional products (including infant formula) as:

  • An economical source of dairy solids
  • An alternative to sweet whey powder, when lower mineral/ash content and a high lactose content is desired for nutritional or flavor reasons
  • An alternative to lactose, when a moderate protein content provides added nutritional or functional advantages
