yes that is why because that limited areas are two close from each and the common sense that our mouth is not too big that it will take time two the food in other taste buds

bitter pill, sour grapes or sweet nothings – descriptions of taste are very often associated with strong emotions. They express in words states of intense pleasure as well as displeasure.
This strong link connecting taste with emotion and drive has to do with our evolution: Taste was a sense that aided us in testing the food we were consuming. It was therefore a matter of survival. A bitter or sour taste was an indication of poisonous inedible plants or of rotting protein-rich food. The tastes sweet and salty, on the other hand, are often a sign of food rich in nutrients.
Sweet, sour, salty, bitter – and savory
Savory dishes that taste of broth evoke pleasant emotions in most people. They are a signal that the food is rich in protein. This flavor has been recognized as the fifth basic taste in addition to the four better known tastes of sweet, sour, bitter and salty. The fact that there are sensory cells specifically for this fifth taste was discovered by a Japanese researcher around 1910, which is why the common Japanese term umami is used for “savory.”
Taste, smell and flavor
What is generally categorized as “taste” is basically a bundle of different sensations: it is not only the qualities of taste perceived by the tongue, but also the smell, texture and temperature of a meal that are important. The “coloring” of a taste happens through the nose. Only after taste is combined with smell is a food’s flavor produced. If the sense of smell is impaired, by a stuffy nose for instance, perception of taste is usually dulled as well.
Like taste, our sense of smell is also closely linked to our emotions. This is because both senses are connected to the involuntary nervous system. That is why a bad taste or odor can bring about vomiting or nausea. And flavors that are appetizing increase the production of saliva and gastric juices, making them truly mouthwatering.
The sense of taste: from the right mix
Based on the information that is transported from the tongue to the brain, there are thought to be at least five basic qualities of taste. Many dishes are made up of a combination of different tastes. Some dishes taste sweet-sour, for example, while others are salty and savory. The basic tastes are:
Sweet
What we perceive as sweetness is usually caused by sugar and its derivatives such as fructose or lactose. But other types of substances can also activate the sensory cells that respond to sweetness. These include, for example, some protein building blocks like amino acids, and also alcohols in fruit juices or alcoholic drinks.
Sour
It is mostly acidic solutions like lemon juice or organic acids that taste sour. This sensation is caused by hydrogen ions, chemical symbol: H+, split off by an acid dissolved in a watery solution.
Salty
Food containing table salt is mainly what we taste as salty. The chemical basis of this taste is salt crystal, which consists of sodium and chloride. Mineral salts like the salts of potassium or magnesium can also cause a sensation of saltiness.
Bitter
Bitter taste is brought about by many fundamentally different substances. In total there are about 35 different proteins in the sensory cells that respond to bitter substances. From an evolutionary standpoint, this can be explained by the many different bitter species of plants, some of which were poisonous. Recognizing which ones were indeed poisonous was a matter of survival.
Savory
The “umami” taste, which is somewhat similar to the taste of a meat broth, is usually caused by glutamic acid or aspartic acid. These two amino acids are part of many different proteins found in food, and also in some plants. Ripe tomatoes, meat and cheese all contain a lot of glutamic acid. Asparagus, for example, contains aspartic acid. Chinese cuisine uses glutamate, the glutamic acid salt, as flavor enhancers. This is done to make the savory taste of foods more intense.
