IIT Hyderabad develops smartphone-based system to detect adulteration in milk

Posted by


Researchers at Indian Institute of Technology (IIT), Hyderabad, have develop smartphone-based system to detect adulteration in milk.

The detector system measures acidity in milk using an indicator paper that changes colour according to acidity. They have also developed algorithms that can be incorporated on to a smartphone to accurately detect the colour change.

IIT Professor Shiv Govind Singh, heading the research team, said, “While techniques such as chromatography and spectroscopy can be used to detect adulteration, such techniques generally require expensive set up and are not amenable to miniaturisation into low-cost easy-to-use devices. Hence, they do not appeal to the vast majority of milk consumers in the developing world.”

“We need to develop simple devices that the consumer can use to detect milk contamination. It should be possible to make milk adulteration detection fail safe by monitoring all of these parameters at the same time, without the need for expensive equipment,” he said.
