Question

Which of the following is used to detect adulteration in turmeric powder?

• A. Hydrochloric acid
• B. Nitric acid
• C. Sulfuric acid
• D. Citric acid

Answer 1

The correct option is A Hydrochloric acid

Adulteration is a process of mixing undesirable and inferior materials in food. The material or substance which is added to food is called as adulterants. Adulterated food is impure, unsafe, or unwholesome food. Turmeric powder is mostly adulterated with metanil yellow. To detect the metanil yellow in turmeric powder, concentrated hydrochloric acid is used. If the pink colour appears instantly but then disappears after adding some water turmeric is pure but if the pink colour remains, then it is adulterated with Metanil yellow.

Thus, the correct answer is option A.
