Contamination of whey by GMPs (Glycomacropeptides)
One of the main markets for whey, apart from that of athletes, is food for newborn babies.
However, we do not give GMP to children , because they can be toxic (1).
Babies should therefore be given either:
- Dairy whey naturally devoid of GMP (premium formula, more expensive).
- Whey cheese in which we have exfiltrated the GMP (first price formula). But, in this case, what to do with all these GMPs that have been eliminated from whey?
Solution 1: Get rid of the GMPs by throwing them down the drain. This is an uneconomical strategy.
Solution 2: we resell the GMPs to whoever wants to buy them. We're not going to make a lot of money out of it, because GMPs don't trade very expensive, but the money taken out is always that of recovered.
GMPs are traditionally purchased by processors (intermediaries between raw material manufacturers and supplement sellers). These semi-wholesalers mix them with their classic whey in order to reduce the cost.
This is how instead of having cheese wheys that contain a base of 20 to 30% GMP, you can easily go up to 50% and some wheys have even been measured at more than 80% GMP after these additions. to reduce the price per kilo of whey cheese.
Warning: some rules of caution
- It is therefore advisable to be wary of whey, especially the first prices;
- You have to demand the GMP content of your whey ;
- Avoid brands that go through processors instead of buying directly from dairies.
As a reminder, Nutrimuscle:
- Does not use whey cheese, rich in GMP ;
- Uses exclusively dairy whey , naturally devoid of GMP;
- Does not add GMP to its whey or protein;
- Does not go through contract manufacturers so as not to sell diluted or adulterated products;
- Buys directly from producers;
- Provides the analysis certificates proving it: native whey , Musclewhey, native whey isolate ;
- Also provides complete product analyzes and supplier names.
