Chennai: Good news consumers! A group of geniuses at the IIT-Madras have made a major breakthrough in the fight against milk adulteration. According to reports, they have developed a device for households that can detect milk adulteration within 30 seconds.
The novel three-dimensional (3D) paper-based portable device can help to monitor liquid food safety and thereby increase the traceability of tainted milk, the researchers of IIT-Madras said.
“The 3D paper-based microfluidic device is made up of a top and bottom cover and a sandwich structure middle layer. This 3D design works well for transporting denser liquids at a consistent speed,” said Dr Pallab Sinha Mahapatra, Department of Mechanical Engineering, IIT Madras, in a statement.
The new invention is happy news for ordinary consumers due to many reasons:
A net to catch them all: Urea, detergents, soap, starch, hydrogen peroxide and sodium-hydrogen-carbonate and salt are some of the most commonly used milk adulterating agents. The new device is capable of detecting them all, among other substances.
Milk testing made pocket-friendly: The major drawbacks of conventional methods of milk testing are that they are expensive and time-consuming. However, IIT-Madras claims that their invention is cheap.
Works on multiple fronts! There is more good news for consumers. Apart from milk, the device is reportedly also capable of checking other liquids such as water, fruit juice, and even milkshakes for traces of adulteration.
Takes very little to reveal the truth: The device needs only a millilitre of any liquid required to test for adulterants, the creators told (ANS).
