Researchers at Monell Chemical Senses Center, USA, discovered new taste sensation. It turned out that along with basic sensations of sweet, sour, salty, and bitter, we are able to detect a taste of calcium. Experimenting on rats, the scientists found two receptors (CaSR and Tas1r3) that are involved in tasting calcium in food.
Taking into consideration the similarity of many human and rat genes, the scientist admit the possibility that humane taste buds can additionally pick out the taste of calcium. Another experiment supports the findings of US researches. The results showed the volunteers found the water with optimal calcium level most preferred. The scientists believe that the detection of calcium by our taste buds is extremely important for people because calcium is one of the most essential elements for human health.
