The following are the methods to find out the following food materials has been adulterated -

(a) Red chilli powder - Red chilli powder is commonly adulterated with brick powder, talc powder.

(b) Rava - Rava is a commonly used item in Indian cuisine. It is usually adulterated with iron fillings.

• To detect the adulteration in ice cream, add 1 ml of water to a test tube containing about 0.5 g of ice cream and bring the mixture to a boil.
• Once it cools, add a drop of iodine to it. If the final output is blue in colour, then it is adulterated with starchy substances.

• We can detect the adulteration of milk with water by the cryoscopic method.
