Scientists have developed a miniature taster with which you can quickly determine the quality of alcohol and food products, as well as differences between several samples of the same brand with an accuracy of 99%.

A team of researchers from the University of Glasgow has unveiled a device that functions in a manner similar to human language. Like humans, a bimetallic nanoplasmonic taster cannot identify individual chemicals, but is able to easily tell the difference between complex mixtures..

Researchers tested the device on whiskey. By placing drops of the drink on small square pieces of gold and aluminum on its surface, which act as taste buds, they measured how the metals absorbed light under the liquid. The slightest color change allows you to create an individual statistical profile of each sample under study.

Based on the data obtained, scientists were able to determine the differences between the same brand from different casks, with an accuracy of more than 99%, as well as the difference between the whiskey aged 12, 15 and 18 years..

According to the developers, in addition to being used to detect counterfeit alcohol, the device can be used to check food safety and quality control..

Earlier we also reported on the invention of a new synthetic alcohol that does not cause hangovers and does not harm the liver.
