Hygolosmia with taste in the mouth is given through a small tube

An electronic tongue that can repeat flavors such as cake soup and fish can help re -create food in virtual reality, but it can not yet simulate other things that affect taste, such as the smell.
Weighs Jia At Ohio State University and his colleagues, she developed a system, called E-Taste, who can take food samples and work on how to partially re-create his flavor in a person’s mouth.
This includes the use of chemicals that correspond to the five basic tastes: sodium chloride for salt, citric acid, and glucose magnesium chloride for traffic and glutamate for the front. “These five flavors already represent a very large group of food we have daily,” says Jia.
The system uses sensors to detect levels of these chemicals in food, and turn them into digital readings, then sends these values to the pump, which pushes small amounts of water -containing gels containing flavor to a small tube under the person’s tongue.
First, the researchers tested the system for individual flavors, and they ask 10 people about the quality of the device in the acidity on a five -point scale, compared to real samples of sour tastes. Give the same number of cloned loads and referee 70 percent of the time.
Then test the team if the system could repeat the most complex tastes – lemon juice, cakes, fried eggs, fish soup and coffee – and asked a group of six people about whether they could distinguish between them, and found that they could more than 80 percent of the time.
However, only focus on flavors like these is not very useful, he says Alan Chalmers At Warwick University, the United Kingdom, because other senses also participate in how we tasted. “The next time you have strawberries, close your nose and eyes. Strawberries are very sour, but it is seen as sweet because of its smell and red. So if you send acid with their devices, you will never know that it is actually from strawberries.”
“The electronic tongue like this is able to extract the amount of sweetness [and] He says: “The acidity, but do not taste a human tongue that realizes them.”
