Ahmedabad Lab Demonstrates How Food Adulteration Is Detected
A food laboratory in Ahmedabad showed how to check chilli powder for unwanted ingredients.
The team performed a live test.
They used two chemicals called solvent ether and hydrochloric acid.
If the hydrochloric acid turned red, it meant the chilli powder contained a dye that is not allowed.
The laboratory also checked for other substances, such as starch.
These tests help identify whether food has been mixed with adulterants.
