Does WPC bind water as well as MPC?

No. Anyone who has seen 10% solids WPC dispersions knows that they’re water thin. So, yogurt manufacturers heat denature the added whey protein along with the whey proteins that are present in the yogurt milk. Heat denatured whey proteins bind significantly more water than do undenatured whey proteins. Heat denatured whey proteins do not, however,…

How do MPC and WPC compare in yogurt applications?

Prior to the introduction of MPC, WPC was commonly used throughout the yogurt industry as the functional protein ingredient to increase yogurt gel strength and decrease gel syneresis (wheying off). A number of dairy industry studies throughout the years have found an increase in yogurt gel strength and a decrease in syneresis in WPC-fortified yogurts…

In processed cheese or cheese analog applications, which type of milk protein does MPC/MPI best replace?

IdaPro MPC/MPI is best used in processed cheese or analog cheese applications to replace caseinates. MPC/MPI can only be used to replace a percentage of rennet casein in those applications before changes in product texture or melt properties become significant. Almost every manufacturer should be able to replace one-third of their rennet casein requirement with…

Why do we measure glutamic acid and not L-glutamine?

By the method used to run an amino acid assay, the amide group on glutamine is sheared off during the breaking of peptide bonds, changing the glutamine into glutamic acid. They are not the same thing…but by an amino acid assay, glutamine always shows up as glutamic acid. Unfortunately, it doesn’t help that the body…

Are any additives used during the filtration process when producing MPI-85 Low Lactose?

Yes. Cold filtration manufacture of IdaPro MPI-85% results in a product with approximately 3.6% lactose. To deliver a product with less than 1% lactose, we utilize a very small amount of lactase enzyme which reduces the disaccharide lactose to its component sugars of glucose and galactose, resulting in a product with a typical analysis of…

If high heat skim milk powder (or NFDM) is used in baking application, how can we claim that IdaPro® MPC powder, which is more like a low heat powder, is also applicable for baking?

First, it is necessary to understand that high heat NFDM is only required for use in some baking applications…not all baking applications. In certain baking applications, high heat treated milk powder is required because whey proteins, in low heat treated powders, that denature during the baking process will interfere with desired final properties of the…

What is the glutamine content of MPC?

Since MPC and MPI are made up of Casein and Whey Proteins, we can look at the glutamine content of each protein to get an idea of the glutamine content of the respective product. Whey protein is reputed to contain roughly 7% to 8% glutamine (per 100 grams of amino acids). Casein has a slightly…

Will IdaPro MPC/MPI behave differently in my application than other powders?

In many cases, yes. You will probably find that IdaPro MPC/MPI delivers a better flavor and more soluble mouthfeel than other MPC/MPI powders. For example, manufacturers of high protein Ready to Drink products have found that they can decrease added flavoring levels and decrease stabilizing salt levels when they use IdaPro MPC/MPI powders compared to…

Does MPC/MPI powder change with age?

Yes. All high protein powders experience degrading chemical reactions as they age. When MPC/MPI powder ages, reactions such as residual fat hydrolysis, loss of solubility, and Maillard browning will continually progress. These chemical reactions are fueled by the concentration of the milk proteins in close proximity with milk minerals and remaining sugar as well as…
