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…
Idaho Milk Products finished MPC is tested on the following schedule for the following items: Test Item Frequency Pesticide and Herbicide Residue semi-annual Heavy Metals semi-annual Dioxins semi-annual Radioactivity semi-annual Melamine and Cyanuric Acid semi-annual
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…
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…
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…
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…
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…
Very little; but there are some differences. It is possible to have a protein powder that is highly soluble but displays poor suspension stability. Conversely, it is also possible to encounter a protein powder with good suspension stability and relatively low solubility. Suspension stability is really a measure of how well the powder stays suspended…
The number one key factor is compatibility of the protein with the other ingredients in the system. For instance, excess free calcium is well known to cause a decrease in milk protein suspension stability and solubility. Sodium phosphate salts are well known to increase milk protein suspension stability and solubility. Probably the second most important…
The response to this question is dependent upon the context in which you are asking the question. In a laboratory situation, suspension stability is measured by dispersing a protein powder in ambient temperature water (10% w/w) and pouring the aqueous protein dispersion into a 100 ml graduated cylinder. One then observes how long it takes…
