Question

which chemical reagent will we use to test the following food items: bread, peanuts, soyabeans

Answer 1

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.
