E-spoon can change the taste of food

Scientists from New York University in Abu Dhabi (UAE) invented an electronic spoon that can change the taste of food with the help of special electrical impulses.

The device, through electrodes located on it, acts on the tongue with special-frequency electrical pulses, which allows you to add a taste of salt, sugar to the food, to make the food sour or bitter. Also, scientists have developed a water bottle with similar capabilities.


According to scientists, these devices are intended for people who, for whatever reason, need to avoid sugar or salt, for example, patients with diabetes or cardiovascular diseases.

On the tests, 30 volunteers were offered clean water and porridge, boiled without salt or sugar. According to reviews, the accuracy of taste ranged from 40 to 83 percent. The most difficult was the "emulation" of bitterness. Also, some test subjects complained about the specific metallic taste of the electrodes, but device inventors promise to correct this shortcoming in the future.

At the moment, an electronic spoon and a bottle are planned to be produced in different colors, for example, blue for salt.
