Taste any flavour without actually eating the food
Scientists at the Meiji University in Japan have come up with something they call a “taste display”. The device can create the taste of any chosen flavor when it is pressed against the tongue.
Humans are able to identify different flavors through the taste buds on their tongues. Taste buds have tiny openings that take in very small amounts of whatever we’re eating. The way these basic tastes combine creates the overall flavor of the food we’re eating.
The five basic tastes are sweet, sour (or acidic), salty, bitter, and umami. Bitter flavors are sharp, like coffee, unsweetened chocolate, or the peel of an orange or lemon.
Together, these five basic tastes create the flavors of everything we eat. Different amounts of these basic tastes create completely different flavors. That’s the main idea behind the “Norimaki Synthesizer” – the new taste display.
One part of the device is a tube that is held in the hand and touched to the tongue. Inside this tube are five smaller tubes. Each contains a gel with the chemicals needed to create one of the five basic tastes.
