Your enjoyment of an apple or a chocolate bar depends on many factors. Taste –the flavor information provided by your mouth is only the beginning. What we think of as flavor also comes from a food’s aroma, texture and even temperature. Scientists have long known that people can identify four basic tastes: sweet, sour, salty and bitter. Some scientists say there’s a fifth basic taste, called unami. It’s produced by monosodium glutamate, a chemical that’s added to improve flavor in foods.
And recently, a scientists found evidence that fat may have a taste all its own. These basic tastes begin as recreations to the chemical makeup of food, molecules of sweet substance, such as sugar and different from those of sour substances and bitter substances and fats. Suppose that you put a piece of candy and sugar molecules are set free. They bathe the taste buds that are located in your tongue, elsewhere in your mouth, and in the upper part of your throat.
