- Proteins can be tested using copper sulfate solution and caustic soda
- Fats can be tested by rubbing a small quantity of food on paper and observing for oily patches
- These tests can be conducted on cooked food items as well as raw materials
Functions of Nutrients
- Carbohydrates provide energy to our body
