Detection of urea adulteration in milk using Gas sensor

Authors(4) :-Valarmathy R S, J. Haritha, Gowthaman S, Jawaharrajan B

Milk adulteration is a global concern. Developing countries are at higher risk associated with it due to lack of monitoring and policies. However, this is one of the most common phenomena that have been overlooked in many countries. Unfortunately, in contrast to common belief, milk adulterants can pose serious health hazards leading to fatal diseases. Apart from regular techniques, recent developments in the detection techniques have also been reported. Nowadays milk is being adulterated in more sophisticated ways that demands for cutting edge research for the detection of the adulterants. The proposed work intends to contribute towards detection of the presence of urea in milk using a gas sensor. The sensor output is connected to a controller and the value is calibrated in terms of concentration (ppm). The concentration of urea is displayed using a LCD. It is observed that the proposed method can detect a minimum of 2mg/lt of urea adulterated in milk at 70C.
