Did you know electricity can alter the way we taste food? Proving this fact is a revolutionary electric fork designed by Japanese researchers that can make any dish taste salty, thus acting as a substitute for the popular seasoning.
According to Hiromi Nakamura, a Post Doc Research Fellow at Tokyo’s Meiji University, the technology can be very useful for people on special diets. Patients with low blood pressure, for instance, can easily go on a low-salt diet and still enjoy delicious food. And with the fork, there’s absolutely no risk of over-salting your food. Luckily, the voltage is so small that there is no risk of electrocution either.
The idea of adding electricity to food was first revealed as an experiment at the Computer Human Interaction Conference in Austin, Texas, in 2012. Nakamura and her team connected a wire to a 9-volt battery and threaded it through a straw placed in a cup of sweet lemonade. Volunteers (who were asked to sign a waiver) reported that the charged lemonade tasted ‘blander’, because the electricity simulated the taste of salt. Nakamura, along with professor Homei Miyashita, now call the idea ‘Augmented Gustation’ and have refined the technology to be able to transfer an electric charge to food through forks and chopsticks.
“The metallic part of the fork is one electrode, and the handle is another,” Nakamura explained. “When you take a piece of food with the fork and put it in your mouth, you close the circuit. When you remove the fork from your mouth, you disconnect the circuit. So it actually works as a switch.”
