It is difficult to navigate through the many preparations of protein in whey powder available in stores or online. Jargon labels often incomprehensible to most consumers are puzzling and do not help. This document will guide you through your choices and make you an informed consumer. Milk contains two primary proteins, casein and whey (whey protein). It is recognized as the best source of protein because of its nutritional quality and excellent digestibility. Whey protein is extracted from whey, a residue from the manufacture of cheese, concentrated and purified to 80% for WPC (concentrate) and 90% for WPI (isolates). The isolates are more pure, contains less lactose and fat that is concentrated is also expensive. All whey is not equal because there are different processes of production from sweet whey, such as thermo coagulation, ultra filtration and micro filtration or ion exchange. Processes using micro filtration and ultra filtration are higher, and can enjoy the full potential of whey and in particular its ability to boost immunity.
[...] Note: The effect glutathione is lost if the protein is heated using pasteurization at 72 C. The properties of the compounds of the whey We now turn our attention to properties beneficial to the health of minor fractions of whey protein (whey). Found mostly in the whey of betalactoglobulin, alpha-lactalbumin, serum albumin and immunoglobulins. The proteins are the minor key or GMP glycomacropeptide, lactoferrin and lactoperoxidase. Beta-lactoglobulin: This fraction most abundant protein in whey. Rich in BCAA (branched chain amino acids) used by the muscles during exercise to generate energy. [...]
[...] This is really not easy to compare protein powders sold commercially. We rarely give the exact quantity of each component and the list of ingredients is often missing. As the manufacturing process of whey, if not indicated, is impossible to guess. For cons the amino acid profile is still there but nobody knows what to do. Here are the important points need to look carefully before you buy your whey. The list of ingredients: The law obliges to place this list on the box and it is with it we can get an idea of the content of our powder. [...]
[...] Example of WPC for sale Analysis 80% WPC concentrated whey protein wet Lactose fat ash Moisture Ultra filtration allows to recover proteins from whey (whey) in non-denatured and the correct levels without heating the whey. The method uses ultra filtration membranes with microscopic holes that enable the selection of proteins from whey and let the water, lactose, minerals. Ultra filtration has been used for decades to separate proteins in a liquid. A new technique, micro filtration to separate more precisely the two milk proteins, whey contained in the whey (whey) and casein milk protein). [...]
[...] As we have seen, the whey protein is obtained from whey, a waste recovered by the cheese industry. This whey protein is purified and concentrated by removing water, lactose and fat remaining. It reached about 80% of proteins in whey concentrates (WPC) and over 90% for isolates from whey (WPI). The isolates are more pure, but much more expensive than concentrates. All isolates from whey are not equal. We shall therefore concern ourselves with the different methods and processes for obtaining whey. [...]
