After having the many lab tests done recently and discovering there were many under dosed proteins on the market, we wondered if there was any way in which the public could easily conduct a test themselves, verifying their protein.
Lab tests are expensive and fussy, so most people don't bother with them, although we strongly recommend they do.
Unfortunately protein testing at home is very difficult, however there is a simple test for carbohydrates, using a long established reagent - "Benedict's Reagent".
Basically, this liquid reacts with any sugars present, lactose, fructose, glucose etc, with a clear colour change evident when sugars are in a product.
Now, given that all popular WPC and particularly WPI's are so low in carbohydrates and sugars, if a scaled test is done then there should be absolutely minimal colour change, if any, that occurs.
These products have virtually no carbohydrates, particularly WPI.
In this test we have designed (using different levels of reagent) when 1 - 1.2 grams of protein is used, there will be no reaction unless sugars are very high.
As you can see from the test, even with sugars at around 20% (200mg sugar 1000mg of WPI), very little reaction occurs, and it in fact takes skim milk powder (which is approx 50% carbs) or a 50/50 blend of dextrose and WPI to give a significant orange colour.
The last video is the most interesting. At 93% "claimed protein", with less than .5% of carbohydrates, there is absolutely no reason why there should be any colour change.
It all makes sense when you realise the "protein" tested at 42% though, obviously in this product a cheap filler has been used (high in carbohydrates), which is why a large colour change occurs.
