Scientists from Scotland through artificial intelligence developed an artificial language used to identify counterfeit alcohol. The artificial tongue can taste differences between the quality of whiskeys that could help tackle the fake alcohol trade. The device used to falsely single-malt scotch or whiskey consists of around two million artificial taste buds. The artificial tongue is coated with different chemicals and contains aluminum and gold; the substance is tested when interacted with light. The technology can also be used to see the difference between the same whiskey aged in a different barrel. The technique can show the difference between whiskeys that are aged for 12 years, 15 years, and 18 years. According to engineers, the tongue can test the difference with more than 99% accuracy.
According to Alasdair Clark, from the University of Glasgow, the artificial tongue acts similar to the human language. The tongue cannot identify the individual chemicals but can easily detect the difference between complex chemical mixture. As per Alasdair Clark, they are not the first scientists to develop an artificial tongue but have developed first single artificial tongue that uses two different types of nanoscale metal taste buds, that provides information related to each sample and provides more accurate and faster response. Dr. Alasdair Clark furthermore said the artificial tongue is a reusable method of testing. The artificial language can be used for identifying forged alcohols and other applications such as in quality control, food safety testing, and security.
The chemists and engineers from the University of Strathclyde and University of Glasgow conducted tests on whiskey. In the trial, whiskey was poured over the two metals, that acts as taste bud and then scientists measure how they absorb light when submerged. The differences in the tests conducted using on the artificial tongue help the researchers identify different types of the whiskeys. The team of researchers used the artificial language to sample different kinds of whiskeys such as Laphroaig, Glen Marnoch, and Glenfiddich.
