Research continue to indicate that the milk-derived compound known as whey may be a valuable weight-loss aid.
Whey is the un-curdled liquid remains of milk that coagulates after the cheese has been strained out. Whey is made out of amino acids, which are the building blocks of protein and possess weight loss and muscle-building properties. These vital peptides are present in miniscule amounts in pre-processed form and, unfortunately, are filtered out of the final product or damaged (denatured) by a high heat or acidic filtering process.
The protein content can range from 35% to 95% whey protein. Obviously, the higher the protein concentration, the more processing (filtering) is needed which adds to the cost. Generally, when the protein level reaches >90% concentration, it’s considered WPI (whey protein isolate).
Micro/nano-filtration whey proteins are cold-processed, cross-flow and probably the finest whey protein on the market today.
