❤️ Answer ❤️

To check for urea in milk, mix half tablespoon of milk and soyabean (or arhar ) powder together and shake well. After five minutes, dip litmus paper for thirty seconds and if there's a colour amendment from red to blue it means that the milk has urea in it.✨❣️

Mix 1 ml of milk with 1 ml of 1.6% DMAB reagent. Distinct yellow colour is observed in milk containing added urea. The control (normal milk) shows a slight yellow colour due to presence of natural urea.
