Answer 2

Answer:

Presence of proteins in the food can be identified by using water, copper sulphate and caustic soda

Firstly, the solid food is crushed and an adequate amount of water is added to the food sample

Then an equal amount of caustic soda (NaOH) and a few drops of 1% copper sulphate solution (CuSO₄) is added to sample

The presence of protein in the food sample is indicated by Purple/ colour

This test for proteins is known as the Biuret test also known as Piotrowski's test
