Taste, the sense that allows us to appreciate the beauty of good food, is something scientists understand fairly well. The sensation we feel when eating a piece of cake, chewing on a hamburger or taking the first bite of a piping hot piece of pizza is triggered when chemicals in our food interact with receptors in our mouths.
For hundreds of years, scientists have known about four basic tastes: sour, sweet, salty and bitter. More recently, a Japanese chemist discovered a fifth basic taste, umami, which is triggered by monosodium glutamate, or MSG, as it’s more widely known. Umami, perhaps best described as savory, is especially prevalent in truffles, meat and anchovies.
And now, scientists believe they have found a sixth basic taste that could profoundly change the way we eat.
