Electronic Tongue to sense taste
Scientists have devised a small, cheap, lab-on-a-chipo sensor that accurately identifies sweetness. It can accurately identify the full sweep of natural and artificial sweet substances, including 14 common sweeteners, using easy-to-read colour markers.
"We take things that smell or taste and convert their chemical properties into a visual image," said study leader Kenneth Suslick, University of Illinois a -Urbana-Champaign (UI-UC). This sensory "sweet-tooth" will help to ensure that beverages taste great with a consistent flavour.
