Explain Whey protein concentrates

Whey protein concentrates (WPC) are  the products derived from whey from which the water, minerals and lactose have been removed.  WPC is a white to light cream-colored product with a bland, clean flavor. It is manufactured by drying the material resulting from the removal of sufficient non-protein constituents from pasteurized whey so that the finished dry product contains 25% or more protein. The non-protein constituents are removed by physical separation techniques such as precipitation, filtration, or dialysis. WPC can be used in fluid, concentrate, or dry product form. Safe and suitable pH-adjusting ingredients may be used to adjust the acidity of WPC.
