However, focusing only on flavours like this isn’t very useful, says Alan Chalmers at the University of Warwick, UK, because other senses are also involved in how we taste. “Next time you have a strawberry, close your nose and eyes. A strawberry is very sour, but it is perceived as sweet because of its aroma and the red colour. So if you send just sour across with their device, you will never know that it is actually from a strawberry.”
Would be curious to only taste a strawberry without the smell and colour. I wonder one would be able to figure out what it was.
