We can test the presence of nutrients like carbohydrates, proteins, and fats in the food.

Some components are present in food ingredients that are required by our body for its proper functioning. These components are known as nutrients. Carbohydrates, proteins, fats, vitamins, and minerals are some of the major nutrients which we obtain from food. 

We can test the presence of carbohydrates, proteins, and fats in our food items as well as in raw ingredients by using certain chemicals. 

Food items containing starch turn blue-black in the presence of iodine solution, those containing protein turn violet in the presence of copper sulphate and caustic soda while those items that leave an oily patch on paper after crushing have fats in them.
