People, nowadays, look for quality at any cost. Surprisingly, in coffee the work of adulterators is involved. Shocked, right? Yes, since we buy grounded coffee powder, we don’t really know about the adulteration that takes place before the final product. In the case of coffee, the most commonly used adulterants are caramel, chicory and date seeds.
Generally, the mixture of these things happens before grinding. Once coffee beans are ground, it is very hard to find the presence of any of the above-mentioned adulterants. Sadly, the real quality which we are supposed to receive gets affected half way through. However, we can find the existence of adulterants in coffee powder through various tests. They are a pinch test, water droplet test, and a tumbler test. Let us look into them.
