Micellar Casein Concentrate

Micellar caseinManufacture of micellar casein concentrates (MCC) and microfiltered milk protein concentrate (MMPC) from milk by microfiltration produces a range of compositions, depending on the amount of milk-derived whey protein removed. Further concentration and diafiltration can increase the total protein and decrease the amount of lactose in the final ingredient.

Unlike milk protein concentrates and isolates, the microfiltration process will alter the casein-to-whey-protein ratio compared to that found in milk. MCC or MMPC cannot be produced by combining separately produced casein (caseinate) and whey proteins.
