How to explain it scientifically, some people think durian is very fragrant, and some people think i

The "smell" of durian has nothing to do with itself, it is actually a problem with the nose!

Because it's inherently stinky, like stinky tofu, you can't just say that it doesn't stink just because some people like to eat it.

Durian, commonly known as civet cat fruit, is a well-known high-quality fruit. The ripe flesh is light yellow, sticky and juicy, soft and sweet, it tastes like old milk cool and onion, it has a peculiar smell at the first taste, and the food is cool and sweet, and the aftertaste is very good, so it has the reputation of "lingering (durian) forgetting to return" (it is said that when Zheng He, a famous navigator of the Ming Dynasty in China, went to the West, he tasted an unknown large cone, and his entourage tasted an unknown large cone, and lingered. So Zheng He named it "Liulian", which is today's durian).

Durian is produced in tropical areas, native to the Malay Archipelago, and is also cultivated in Hainan, Liangguang, Hunan and other places in China. The fruit has a strong aroma and sweet flesh, and is known as the "king of fruits".

Containing a variety of signature nutrients, it is regarded by the locals as the "king of tropical fruits". There is a folk proverb in Thailand: "When the durian comes out, the sand cage is taken off." It means that the girls would rather take off their skirts and sell them than have a full meal of durian.

Efficacy Durian is rich in protein and lipids, which has a good nourishing effect on the body and is a good fruit nutrition**.

Durian has a special smell that different people feel differently, some people think it smells like cat feces, and some people think it has a rich aroma. In fact, it may be because the musk smell is too strong, but I think it is stinky, just like perfume spills too much and it smells bad. The smell of durian has the effect of appetizing and promoting appetite, and the dietary fiber in it can also promote intestinal peristalsis.

Turnips and cabbages have their own love My family hates eating durian, but I love it.

The food recognized by the Chinese people has good color, flavor and taste. Among them, color - the appearance of food, fragrance - the smell that the nose can smell, is often an important premise for people to judge the taste of a certain food. However, there are some special foods that stubbornly and stubbornly "hide" the fragrance and "dew" smell, which makes people stay away at first, but can give people unexpected surprises after tasting.

It's prickly and smelly. Durian, the first impression left on most people, seems to be "terrible" because of this. However, if you "have the courage" to let the tip of your tongue get close to it, you will often find that this guy's taste is really soft and sweet.

Why does durian smell and eat deliciously? What problems should I pay attention to when eating durian? Experts in food processing and tropical fruit research are here to help us uncover the truth.

1 Say that durian smells like where it comes from.

Durian is a tropical evergreen tree belonging to the genus Durian of the order Malvacaceae, which is a perennial evergreen typical tropical fruit tree, with oval-shaped fruits, pale yellow or yellow-green, and conical thick spines on the outside.

It takes 4 to 8 years for durian to bear fruit after planting. Don't look at its hard thorns and strong appearance, but it is actually a very delicate tropical fruit tree: more than 6 to ensure the survival of the fruit tree, the average annual temperature is more than 22, and it needs fertile land and sufficient rain to flower and bear fruit, it is a perennial evergreen pure tropical (typical tropical) fruit tree.

Therefore, even in countries such as Southeast Asia, the origin and main production area of durian, the durian tree will not bear fruit at a slightly higher altitude and a little lower temperature.

The earliest document recording durian in China is Zheng He's deputy Ma Huan's navigation diary "Yingya Shenglan". This is a kind of "stinky fruit" called "gambling eryan" by Ma Huan: if the stinky beef stinks, there are 14 pieces of crispy white meat in it, which is very sweet and delicious.

Zhou Zhaoxi, an associate researcher at the Chinese Academy of Tropical Agricultural Sciences, said that durian's "smelly" property depends on its characteristic volatile sulfur-containing compounds (rotten egg smell), which are activated during ripening and make durian "smelly". Moreover, because the odor is extremely volatile, it can be easily identified from tens of meters away.

The reason for "eating fragrant" is that durian contains aromatic ester compounds such as tung bend ethyl butyrate and ethyl propionate. The combination of the two forms the unique taste of durian's "stinky and smelly".

The smell and fragrance of durian are also related to people's sense of smell. Studies have shown that there are more than 400 kinds of olfactory receptors that humans perceive smells, and about 30% of the olfactory receptors of any two individual individuals will be different, so each individual's ability to receive odors is also different, which largely determines why some people think durian is very fragrant, while some people can't accept the smell no matter how smooth they are.

<> durian is stinky. The pulp of durian is dominated by sulfur-containing compounds, such as diallyl trisulfide, diallyl disulfide, diallyl tetrathialofen, etc. These sulfur-containing compounds have a pungent taste, so the pungent smell of durian is accompanied.

The inner and outer peels of durian are dominated by ester compounds, which make durian smell like a mixture of fruits. In addition to its strong fruity flavor, durian also has a strong onion flavor. Because durian seeds contain organic lead compounds such as palmitic acid, methyl palmitate, and ethyl oleate, they make durian very unique, and the smell is penetrating and can be smelled from a few meters away.
