Based on this labeling style there is little chance you will know how much protein you are actually getting from this source. Unfortunately you will see a trend of this vagueness develop as you continue reading. Whey is the protein that most people are familiar with and seem to feel most comfortable discussing. Most of the world s whey comes to the supplement industry as a byproduct of either cheese or plastic production, yes I said plastic. More about plastics when we get to casein.
Cheese whey is produced during the separation of casein and whey as the curd for cheese is produced.
Generally speaking milk is treated with an acid and causing a shift in pH which makes the casein coagulate and fall out of suspension. What is left uncurded on top of the casein is raw whey. The raw whey is collected and then undergoes serveral processing steps before it is dried as a protein powder. Whey protien powder generally comes in three different categories of protein concentration. In general the greater the amount of protein the lower the carbohydrate and fat, and the higher the price.
