Question

chemical regent we use to test the following food items bread, peanut, paneer, soyabean, banana, boiled rice and potato​

Answer 1

Answer :

Bread can be tested using Iodine; Peanuts can be tested with a tissue paper and Soya Bean can be tested using Copper Sulphate.  

Explanation:  

As starch is the main component of bread, therefore chemically this can be tested by using the Iodine solution.

Peanuts contain a host of healthy fatty acids and are extremely good for the heart when taken in moderation.

As their main component is fat, only a tissue paper can be used to test them as soaking peanuts would lead to the creation of an oily patch.

Lastly, as soya beans are a rich source of protein this food can be tested using copper sulphate as well as caustic soda.

These type of food items are generally are natural but they can be tested by man made substances.
