Researchers develop battery-powered fork to simulate taste of salt

Device that adds the salty taste, but without actually adding the salt

Tokyo (IINA) – Researchers at the University of Tokyo have built a device that adds the salty taste, but without actually adding the salt, Mail Online reported.
A battery-powered fork will electrically shocks taste buds to simulate the taste of salt, as well as also sourness and different food textures.
Still in the prototype stages, the device is geared towards individuals who are on low-salt or salt-free diets but still crave the taste, reports Nikkie Technology.
"It's a technology that allows electricity to be used as seasoning," said Hiromi Nakamura, a researcher at the University of Tokyo, who is part of the "No Salt Restaurant" project that aims to improve local diets.
"(The fork) will satisfy the desire of those wanting to eat a healthy diet that is also full of flavor."
The handle of the fork houses a rechargeable battery and electric circuit. The battery life lasts for about six hours, although the prototype is not water-proof.
Users put the prongs in their mouth with food on it, while pushing a button on the handle. A soft electrical current is then sent to the tongue.
Researchers warn that if you push too far with the fork, it will create an unpleasant metallic taste in the mouth.
Currently, there are three levels of saltiness available in the device, which cost researchers $17.70 to make, in addition to the cost of the fork.
