Coffee common sense 10 little secrets about taste

[the translator is wrong] have you ever studied taste distribution map? Sweet taste buds at the tip of the tongue; bitter taste buds at the root of the tongue; sour taste buds on both sides?

The truth is: you can taste everything in every part of the tongue, although the sensitivity may be different.

[fifth feeling] it is well known that the tongue has four tastes: sweet, salty, sour and bitter. But many people do not know the fifth feeling of the tongue: delicious taste. This is a basic sense of taste that has only recently been discovered. Scientists have recently discovered that there are taste buds not only on the tongue, but also throughout the digestive tract. However, the effect of intestinal taste receptors on digestion and nutrition is not clear. Soy sauce, tomatoes and many foods rich in glutamate can bring this taste.

[taste buds on nipples] the particles on the tongue are not taste buds, but fungal nipples. There are 50 to 100 taste buds on each mushroom-shaped nipple. There are only a few taste buds that feel sweet, sour, salty and fresh, but there are at least 25 taste buds that feel bitter. The advantage of being so sensitive to bitterness is to avoid our poisoning. Many poisonous plant ingredients, such as brucine and cyanide, are bitter.

Sweets and alcohol excite many of the same reward circuits in the brain. Research shows that children with a family history of alcoholism prefer sweets. Endogenous cannabinoids, a neurotransmitter in these circuits, enhance the sense of sweets, the study explained.

[mystery fruit] A fruit native to West Africa contains a glycoprotein called mystery fruit protein. After the mysterious fruit protein binds to the taste buds, eating sour food also feels sweet. The fruit takes the lead in flavor modifiers, and the berries, or pills containing mysterious fruit protein, can make foods like lemon taste as sweet as lemon pie.

Food scientists at the University of Florida have successfully transferred the mysterious fruit protein gene into tomatoes and strawberries. Their goal is to cultivate fruits and vegetables that are low in sugar but very sweet.
