The organs that perceive taste are mainly distributed in the tongue, and there are also a few taste buds in the palate and throat. Choose sugar, salt, lemon juice (bitter taste in lemon may interfere with practice) and bitter gourd, taste and chew them in turn, and try to feel which part of the mouth is most sensitive to the above four flavors.

When the above contents are mastered skillfully, you can practice the familiarity of spicy fresh minerals. The samples are pepper, monosodium glutamate, mineral water and pure water, and the training purpose is the same as that mentioned above.

Finally, a comprehensive comparative test is carried out. Use soft candy, rock candy, brown sugar, or samples with very similar taste experience, such as ordinary lemon and green lemon, to practice the discrimination between taste persistence and similar taste (this will involve distinguishing subtle differences such as fresh, spicy and mineral sense on the premise of four taste expressions).

2, exercise taste discrimination method:

Feedback on the stimulation or intensity of teeth and mouth is a way for us to experience different tastes, such as soft, hard, waxy, crisp, moist, dry, slippery, astringent, alcohol and thin. It is not difficult to exercise taste discrimination. Taking apples, potatoes, radishes and onions cut into equal thickness as samples, practitioners will blindfold, hold their noses and feed them into their mouths with chopsticks (of course, it is best to ask others for help).

If it is a big environment, it is best to have green plants next to it, which can purify the air, so that when you are in a very clean environment, the words smell and taste are well preserved. When there are different smells or exciting smells, you will be the first to reflect them. It is also beneficial to exercise in this respect at ordinary times.
