Do you know electricity can change the way we taste
food ?Proving this fact is a revolutionary electric fork
designed by Japanese researchers that can make any dish
taste salty.
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 high 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 the ir food.Luckily ,the voltage(电压) is so small that
there is no risk of electrocution(触电) either.
The idea of adding electricity to food was first exposed as an
experiment at the Computer Human Interaction Conference in
Austin ,Texas ,in 2012.Nakamura and her t eam connected a
wire to a 9-volt battery and passed it through a straw placed in a
cup of sweet lemonade.Volunteers reported that the charged
lemonade tasted “blander”,because the electricity created
the taste of salt.
Nakamura has improved 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(电极) ,
and the handle is the other ,” Nakamura explained.“When you
take a piece of food with the fork and put it in your mouth ,you
connect the circuit.When you remove the fork from your mouth ,
you disconnect the circuit.So it actually works as a switch.”
Simon Klose ,host of food program Munchies ,who
recently visited Nakamura to try out the fork himself ,called this
form of “food hacking” one of the greatest eating experiences
he’d ever had.
“When I first heard of electric food,it sounded scary ,”
he said.He later continued to use a charged fork to eat pieces of
fried chicken ,an
