Answer 2

Protein can be detected by using water copper sulphate and caustic soda.

• In this protein detection method, we crush the food materials into paste like material.
• Then we add that food material into a test tube along with a few drops of water.
• After that, we add copper sulphate and caustic soda solution in that test tube with the help of a dropper.
• If a violet colour appears inside the test tube, then we can easily tell that there is traces of protein in the taken food material.
