How to tell whether mustard powder is true or false?

Generally, the adulterated mustard powder has rough packaging, and the packaging surface is difficult to identify and easy to fall off. Most of them don't write detailed factory names and addresses, and some only use Chinese Pinyin and English letters to indicate the place of origin. Pure mustard powder should be clearly marked. If it is imported mustard, it will also indicate the import and export batch number, origin and other information.

The color, particle size and smell of adulterated mustard powder vary with the substance and adulteration amount of adulterated mustard powder. At present, grains mixed with yellow, such as corn flour, are pale yellow or golden yellow, and the pungent taste is obviously weakened.

Wash mustard powder repeatedly like rice washing and sand filtering. Because of the high density of grain powder, it will remain in the container. Taste it with your mouth. If there is no obvious mustard smell, it means that there are grains mixed.
