There is always a risk of your kitchen ingredients being adulterated. For instance, the maida or rice flour you use at home may look pure but there are chances of it being adulterated. So, why not test it before consumption?
Food Safety and Standards Authority of India (FSSAI) pointed out in a tweet that maida can be adulterated with boric acid, a weakly acidic hydrate of boric oxide.
FSSAI recommended the following test to check adulteration in maida:
*Take 1 gm of maida in a test tube.
*Add 5 ml of water to it.
*Shake the contents in the test tube.
*Now add a few drops of concentrated HCL (Hydrochloric acid).
*Dip a turmeric paper strip to the solution.
*No colour change will be observed on the turmeric paper if the maida is unadulterated. However, it will turn red if the maida is adulterated.
