Tongue Tip Can Fell 7 New Taste Sensation

News Health Articles - Tongue Tip Can Fell 7 New Taste Sensation. Basic tastes that can be sensed by the tongue as long as there are only four of sweet, bitter, sour and salty. But lately, the development of science also recognizes savory and some other new flavors as well as a basic taste.

The ability to sense five basic tastes received from the senses of receptors taste. Small sensory organs arise mainly in the tongue, palate and in the back of the throat. The sense of touch also plays a key role in experiencing a sense.

The Following seven taste sensation that can be considered as a basic taste, as quoted from FoxNewsHealth, Wednesday (January 4, 2012):

1. Calcium

The new results have revealed that, in rat has taste receptors for calciums 2. One of the receptors have been found in the human tongue, although its role directly in the taste of calcium is not enough to understand, says Michael Tordoff, a behavioral geneticist at the Monell Chemical Senses Center, Philadelphia.

2. Kokumi

That the calcium receptor may also be something to do with a potential unrelated sixth sense called kokumi, which translates as "mouthfulness" and "heartiness". Kokumi has been announced by researchers fro the same food company in Japan, Ajinomoto, which helped convince the world for the fifth basic taste, ie savory.

3. Spicy (piquance)

Some Asian cultures regard spicy as a basic taste sensations, known in English as piquante(from France). Historically, however, food scientists have not classify spicy as a basic taste sensations.

4. Coolness

Taste sensation may describe the sensation of coolness and fresh mint from peppermint or menthol. Sensory perception work on taste, touch-activated receptor, called TPRM8. As the sensation of touch, both piquance and coolness that is transmitted to the brain via trigeminal nerve, not three classic nerve to taste. The set of nerves that carry sensations of burning and cooling is different from the sensation of taste.

5. Metallicity

Metallic taste, such as gold and silver can also be felt in the oral cavity. The researchers have shown that, the sensation of taste is probably something to do with the electrical conductivity. "It is like a small battery, with a drop of saliva, then it will get about 550 millivolts," says Harry Lawless, a professor emeritus of food science at Cornell University.

6. Fat
Many people who enjoy fatty foods. The results have showed that mice can taste the fat. It seems that humans can also feel fat. The results of these studies have been published in the British Journal of Nutrition. Fatty acids tend to taste bitter in the mouth.

7. Carbon Dioxide

When dissolved in liquid, gas provides soda, as in beer champagne and other carbonated beverages. The tingling sensation as the alleged result of the bubble that burst on the tongue. "CO₂ has been always considered as a trigeminal stimulus," Tordoff said.

The researchers found that an enzyme called carbonic anhydrase 4 appears on the cells that can sense a sour taste, especially to detect carbon dioxide in rats. Further evidence comes from a drug called Acetazolamide, often taken by the climbers to avoid altitude sickness. Acetazolamide blocks the activity of carbonic anhydrase 4.
