What is taste
"You taste sweet, sour, salty and bitter. You don't taste hot, it's just a kind of burning sensation on the tongue," says Ansgar. In addition to sweet, sour, salty and bitter, there is a fifth taste: umami - this is the name given to the taste of meat. In the past, taste was particularly important. It was through him that people knew what, for example, was poisonous. Much that is toxic to the body usually tastes bitter or sour and only rarely tastes sweet. People therefore preferred to keep their hands off sour and bitter things. Sweet and salty - that is, a pleasant taste - meant that something was high in carbohydrates or other important elements, for example.
It doesn't work without the tongue
"The tongue has the taste cells. When we eat a cake, for example, we taste everything with the tongue," says Isabel. "The tongue is divided into several parts. On the sides there is an area where you can taste something, then in the middle, front and back. There you always taste different tastes. "On the tongue we have the so-called papillae. You can even see them: It is the rough surface on the tongue. The taste cells are located in these papillae, says biology teacher Heike Bresser:" It is on the tongue Taste sensory cells. When certain aromas from certain dishes hit the regions of the taste regions or sensory cells, they are stimulated and send certain taste sensations towards the brain. "The brain then decides whether we like this taste or not.
Taste is closely related to smell
In order for the sensory cells on the tongue to be able to taste anything at all, the food must first be dissolved in the saliva. And the nose also plays a role, says Janne: "The tongue can somehow differentiate between sweet, sour and bitter - and the rest is almost done by the nose." And Karla adds: "I once held my nose and then tried to eat something, I somehow only tasted half of it." And Ms. Besser also says that the taste is closely related to the smell. "Because some people who can't smell so good can't taste that good either."
Try the asparagus!
In the course of our lives our tastes change. Most of the time, when we're young, we find bitter foods gross. And as adults we suddenly taste things like coffee or asparagus. And of course each of us has our own taste. Oke, for example, prefers anything that tastes salty. And Lennie prefers sweet things - just like Ms. Bresser: "Chocolate flavor!"
