SCREENING OF ADULTERANTS IN MILK
Author: Pradeep S., P. Lakshminarayana, Varsha R., Shriya K. Kota
Milk is the most commonly adulterated consumable in India. The addition of urea, detergent, sugars and vanaspati oil to create synthetic milk render it unfit for consumption according to the standards that define the quality of milk. This paper investigates the different milk adulterants and two methods of detecting them. The chemical methods of testing and electrical conductance method were performed. It was found that urease test can detect as low as 0.2 g/L of urea present, iodine test for starch is able to detect 0.04g/L starch present and the sensitivity of Benedict’s test is 5g/L. It was also observed that there was significant difference in conductance of adulterant containing milk from that of raw milk. Therefore these methods can be used for reliable detection of adulterants and can be incorporated into a device for easy detection of adulterants.
