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.
