MPI

Milk Protein Isolate

Product Definition

Milk Protein Isolate (MPI) is obtained by concentrating bovine skim milk through filtration processes so that the finished dry product contains at least 90% protein by weight. MPI may be produced by filtration, dialysis, or any other safe and suitable processes by which all or part of the lactose and minerals may be removed. The product cannot be manufactured by combining separately produced ingredients, i.e. casein (or caseinates) and whey proteins.

MPI is produced by filtration methods (ultrafiltration and diafiltration) which capture essentially all the casein and whey proteins contained in the raw material stream, resulting in products with a casein-to-whey protein ratio equivalent to that of the original milk, generally a value of 90:10.

MPI complies with all provisions of the U.S. Federal Food, Drug, and Cosmetic Act.
