Cocoa powder is a food raw material, and the national standard gives strict regulations on its production. In the absence of testing instruments, it is possible to judge whether it is good or bad by simple methods, mainly from its color, smell, fineness and fat content.
Look at the color
1. The color of natural cocoa powder should be light brown. For brown or even dark brown natural cocoa powder, cocoa peel or other food coloring must be added.
2. The color of alkalized cocoa powder should be brown-red. If it is dark brown or brown-black, it must be due to excessive alkalization and excessive ash content.
3. The color of cocoa black powder should be dark brown to brown-black. If the color of cocoa powder is pure black or even dark black, it means that food coloring must be added to the cocoa powder.
