IIT Madras Researchers developed a three-dimensional (3D) paper-based portable device that can detect adulteration in milk within 30 seconds.
The test could be even performed at home.
It can detect multiple substances commonly used as adulterating agents including Urea, detergents, soap, starch, hydrogen peroxide, sodium-hydrogen-carbonate and salt.
This new technology is affordable and could also be used to test other liquids such as water, fresh juices, and milkshakes for traces of adulteration.
