Scottish researchers have developed an “artificial language” for recognizing counterfeit whiskey. The device detects small differences between whiskeys, which could help eliminate the alcohol counterfeiting market, researchers say.

The tiny sensor recognizes the differences between beverages by utilizing the optical properties of gold and aluminum. It can distinguish if the same whiskey is aged in different barrels and recognizes the difference between 12, 15 and 18 year old whiskey, the BBC writes in its news portal.
Its creators, engineers at the University of Glasgow and Strathclyde, say the sensor “tastes” the differences with 99 percent confidence.
Alasdair Clark, a researcher at the University of Glasgow, said: “We call it artificial language because it behaves like human language. Like us, it can’t identify the individual chemicals that make coffee taste different from apple juice, but it can easily identify the difference between the two complex chemical mixtures “.
The submicroscopic slices of “artificial” gold and aluminum, arranged in a chessboard pattern, behave like taste buds. Researchers poured samples of whiskey on these “taste buds,” which are about 500 times smaller than their human counterparts, and measured how they absorb light while covering it with liquid – reads at Glasgow University tomorrow.
The subtle differences in the light absorption of metals in artificial tongue have been statistically analyzed, allowing researchers to identify different types of whiskey.
“We are not the first to create an artificial tongue, but the first to create two” taste buds “of two different metals. This gives us more information about the ‘taste’ of the patterns, allowing for a quicker and more accurate reaction,” he explained. the experts.
Clark pointed out that the device is capable of analyzing virtually any liquid, not just whiskey.
“In addition to identifying counterfeit alcohols, it can be used, for example, in food safety testing, quality control, and in virtually every area that requires a portable, recyclable tasting method,” Clark explained.
The device was announced Tuesday by its creators in Nanoscale.
