IIT-Madras-led innovation can detect adulteration in milk in 30 seconds
New Delhi, Mar 30 (PTI) Researchers have developed a three-dimensional (3D) paper-based portable device that can detect adulteration in milk within 30 seconds.
The test, which could be performed at home, can detect multiple commonly-used adulterating agents including urea, detergents, soap, starch, hydrogen peroxide, sodium-hydrogen-carbonate and salt, among others, they said.
Requiring only a millilitre of a liquid as a sample for the test, the researchers said that the test can be used to detect adulteration in other liquids as well such as water, fresh juices and milkshakes.
