2. Describe one test each for detecting the presence of the following in food:

(a) proteins

(b) starch

(c) fats


(a) Test for Protein

Materials Required: Mortar and pestle, test tube, dropper, concentrated nitric acid. 

Procedure: Crush some bean seeds in a mortar and pestle. Make a suspension using water. Take a little of this suspension in a test tube. Very carefully, add a few drops of concentrated nitric acid to it. If the colour of this suspension changes to yellow, it indicates the presence of proteins.

(b) Test for Starch

Materials Required: Iodine solution, test tube, dropper

Procedure: Take the material which is to be tested. Add iodine solution with the help of a dropper If it turns blue-black, it indicates the presence of starch.

(c) Test for Fats

Material Required: Paper.

Take the given food item and rub it on a dry paper. If fat is present in it, it will leave a translucent mark on the paper.

3. Why do we need proteins and how do they affect our health?


Proteins are the building blocks of life. Every cell in the human body contains protein. We need protein to help our body repair cells and make new ones. 

Proteins are made up of carbon, hydrogen, oxygen, nitrogen; and a small quantity of both sulphur and phosphorous. Proteins help in building up the developing tissues of a growing child. They also take care of the ‘wear and tear’ of the body tissues at all ages.

4. A mineral ‘X’ is essential for the formation of a component ‘Y’, in the blood of a person. The function, of component Y. is to transport oxygen in the body. The deficiency of mineral ‘X’, in the diet of a person, causes a disease Z. Identify X, Y and Z. Also mention the symptoms of disease Z.


The mineral X is iron which is essential for the formation component Y which is haemoglobin and the disease Z is anaemia.

An anaemic person appears pale and weak. The body shows fatigue, loss of appetite, whitening of nails and swelling of hands and feet.
