Milk Protein Isolate (MPI) is produced by filtration methods (ultrafiltration and diafiltration) that capture essentially all the casein and whey proteins contained in the raw material stream of the finished product. This results in a casein-to-whey-protein ratio equivalent to that of the original milk (approximately 80:20) without combining separately produced casein (caseinate) and whey proteins. MPIs have a minimum of 90% protein (generally in the range of 90% to 91% protein by weight). It contains very little fat (typically less than 3%), carbohydrates or lactose and can be used as a daily supplement for those who do not consume the recommended amount of protein in their diet or those who are lactose intolerant. Milk Protein Isolate has very high amino acid composition that makes it ideal for use in protein bars and meal replacement powders.
