Development of an Experimental Setup for Detecting Extent of Urea Adulteration in Cow Milk using Polytetrafluoroethylene

Abstract

Adulteration of food is a global concern. Due to lack of stringent measures, many consumers are at risk of
contracting diseases. Hence, there is a need for a method which would detect the adulteration of food and also quantify
the degree of adulteration.Cow Milk is one of the most commonly used household products in India. It is a daily
requirement in almost all houses. Adulteration of milk is done by adding harmful chemicals in milk to increase its
quantity for economic purposes. Urea is a common adulterant in milk which, when added to a certain extent, has
damaging effects on the human body. These can be hearing impairments, cancer, heart problems, and can even be fatal in
some cases.his paper proposes a method to detect the amount of urea added in milk using Polytetrafluoroethylene
(PTFE).
