Diners in Japan could soon be able to savour the umami of a bowl of ramen or miso soup without having to worry about their salt intake.
In what they claim is a world first, researchers have developed chopsticks that artificially create the taste of salt, as part of efforts to reduce sodium levels in some of the country’s most popular dishes.
The chopsticks work by using electrical stimulation and a mini-computer worn on the eater’s wristband.
The device transmits sodium ions from food, through the chopsticks, to the mouth where they create a sense of saltiness, according to Homei Miyashita, a professor at Meiji University in Tokyo, whose laboratory collaborated with the food and drink manufacturer Kirin to develop the device.
