Easy Test for Identifying Fake Whey Protein
Hi Guys. I work for The Protein Factory and I want to share something extremely important with everyone. It is very disappointing to see so many fake proteins in the market these days. There is an easy test that can be very helpful in identifying fake whey proteins. Real whey protein forms rubber like clumps when mixed with boiling water. Take a cup of boiling water and mix 2-3 Tablespoons of whey protein. You will notice that the clumps are elastic and rubbery. Now you might be wondering that real whey protein clumps in room temperature water also (if you mix in a glass not a shaker) so how will you understand the difference? The clumps in room temperature water are different. They break up with time and if you keep mixing for a long time they can disappear. But in boiling water, the clumps will stay no matter how much you mix with the spoon. The science behind it is that whey protein denatures in hot water. The amino acid chains unfold and stick to each other. And this process is irreversible so the clumps stay no matter how much time passes. Fake whey proteins are filled with dextrose. When you mix them in boiling water they will easily dissolve without any issue. Please note that this test is only for whey protein. Vegan proteins behave in a different way. Also, this test is going to separate fake from real but it cannot give you the purity of the protein. For that, protein content testing and amino acid profile testing needs to be done.
