Urea (CH4N2O), being a soluble agent is the commonly found adulterant in milk and other dairy products. The normal concentration of Urea in milk is expected to be around 10-14 mg/dl. Urea is generally added in milk to increase the Solid Not Fat (SNF) value. An investigation of different methods available for the detection and quantification of urea in milk is carried out in this paper. Also, a comparison is drawn between the various methods available and the optimal one is chosen in terms of factors like portability, durability, high sensitivity, accuracy and precision.
