Milk going bad seems to be a major problem in fridges all over the world, with people trusting their not necessarily too accurate sense of smell to find out whether their drinks have been spoiled - but the new sour milk test technology will be changing this for the better!
A team of scientists in two major universities on different sides of the world, the University of California Berkeley and the National Chiao Tung University in Taiwan have been developing a new sour milk test technology that allows electrical components to be embedded on cap bottles for milk, which would be able to test how bacteria changes once milk goes bad.
According to The Huffington Post, the team behind the sour milk test is composed of engineers, and their new product involves a complex circuit that includes capacitors, inductors, resistors and wireless electrical sensing systems.
Tech Radar reports that, in theory, once the sour milk test caps are ready, all they would need to get to see whether milk has gone bad is a quick flip to the milk carton, as that will splash the cap with enough of the drink to provide an accurate reading on the amount of bacteria that can be found in the carton, thus finding whether or not it's spoiled.
"This 3D-printing technology could eventually make electronic circuits cheap enough to be added to packaging to provide food safety alerts for consumers," Liwei Lin, one of the engineers behind the sour milk test, described. "You could imagine a scenario where you can use your cellphone to check the freshness of food while it's still on the store shelves."
According to The Wall Street Journal, this new invention isn't solely about spoiled milk, as it can also serve as the prototype for future unpowered sensors that could determine different sorts of contaminants, including daily diabetes data and blood pressure or contamination.
In any case, the sour milk test is very impressive technology in the making!
