Test for Proteins :
To the test the presence of Protein in food we prepare 2% CuSO4 solution by mixing 2g in 100 ml of distilled water.
Prepare 10 % NaOH solution by adding 10g in 100ml distilled water.
Now Mix 2 drops of 2% CUSO4 solution and 10 drops of 10% NaOH solution in milk.
After some time we get Violet colour which shows the presence of proteins in milk.
