Identifying adulteration in food
Tea powder: Soak two papers in water and spread a small amount of tea powder over it. If the paper colour changes, it means the powder sample is adulterated.
Food (edible) colour and black pepper powder: Sprinkle two drops of lemon in food colour. If adulterated, then colour changes to black.
Tur dal / Chana dal: Can be mixed with laakh dal, which is bigger and not round in shape. It is hard to cook.
Spices: Original clove should be a dried long stick and have a fully blossomed flower over it.
Milk: Add a pinch of iodine in milk and if adulterated colour of milk changes to blackish blue.
Gold: Sought as long term investment, should have embossed insignia of the Bureau of Indian Standards (BIS) hallmark which indicates purity of the metal, logo of jeweller, Bombay Gold Centre (BGC) mark and year code letter.
