E-tongue can detect white wine spoilage before humans can - EurekAlert
<p>While the electronic tongue bears little physical resemblance to its namesake, the strand-like sensory probes of the “e-tongue” still outperformed human senses when detecting contaminated wine in a recent study. In an experiment at Washington State University, the e-tongue identified signs of microorganisms in white wine within a week after contamination—four weeks before a human panel noticed the change in aroma. This was also before those microbes could be grown from the wine in a petri-dish. Winemakers traditionally rely on these two methods, sniffing the wine and petri-dish testing, to identify potential wine “faults” or spoilage. The findings indicate that e-tongue testing could augment those methods and allow winemakers to catch and mitigate problems sooner, said Carolyn Ross, WSU food science professor and the study’s corresponding author.</p>
