What is the use of eating durian? Why is it so expensive?

There is a folk saying that "a durian raises three chickens"

Durian is rich in folic acid, protein and carbohydrates, and it is hot. People who are suitable for yin-cold constitution eat more, which can improve yin-cold constitution and enhance people's resistance. Many women have a bad cold and are often troubled by dysmenorrhea. Eating durian can promote blood circulation and dispel cold, nourish yin and strengthen yang, replenish qi and blood, and relieve dysmenorrhea. Durian has extremely high nutritional value. Regular consumption can strengthen the body, strengthen the spleen and replenish qi, tonify the kidney and strengthen yang, and warm the body.

A durian pulp contains starch 1 1%, sugar 13%, protein 3%, and trace elements such as fat, vitamin C, calcium, iron and phosphorus, which is quite rich in nutrition. In Thailand, the hometown of durian, durian is often used to nourish sick and postpartum women. Durian shell boiled bone soup is a good tonic, and the core and pulp are often used to stew chicken soup. This kind of soup friendship can invigorate qi, besides stomach cold, it can also be used as a tonic for women.

Although durian is rich in nutrition, it has the effects of invigorating spleen and qi, tonifying kidney and strengthening yang, but it is not advisable to eat more at a time, and it is best not to exceed 100g every day.

People with certain diseases may even cause sudden death. The Thai Ministry of Health once advised people not to eat more than two pieces of durian a day.

Durian is a warm fruit. If it is easy to get angry, it is best not to eat more durian, which will lead to the symptoms of getting angry. Patients with weak constitution should also eat durian in moderation, and pay attention to eating durian in moderation every day. They can't eat in large quantities, which will lead to heat in the body.

Second, why durian is so expensive:

1. Durian is a tropical fruit with a huge body. Tropical trees grow very tall, such as coconuts. The durian tree can be as high as 25 meters, but the shell of durian is very hard and the whole body is covered with big thorns, so picking durian itself is a technical job, otherwise it will really be killed!

In recent years, there is a growing demand for durian in China, but there is no durian in China, so things are rare and expensive, forming a seller's market. Most durian imported from China comes from Thailand and Viet Nam, and 80% of durian orchards in these two countries are now occupied by fruit merchants in China, which also makes durian, once a common producing area, more expensive locally.

3. Transportation costs. Durian is not easy to store, so the import transportation mode of durian in China is basically car transportation, and the transportation cost of pulling a container of durian to Shanghai and Beijing doubles every 20,000 to 30,000 holidays.

Durian is easy to wear and tear, and tropical fruits are easy to deteriorate, so this cost will be counted when selling.

Third, why is durian so smelly:

The unopened durian smells like grass when it is immature, while the mature durian exudes its inherent fragrance.

The smell of durian pulp is mainly caused by sulfur compounds. Researchers have done experiments, and the sulfur compounds in pulp volatiles are mainly diethyl disulfide, ethyl n-propyl disulfide, diethyl trisulfide and 3- ethyl 2,4-dithio -5- hexanone. Sulfur compounds generally release a pungent smell, which is why durian smells so "smelly". The peel and pulp of durian are also rich in ester compounds, which will make durian smell fragrant and fruity.

Because everyone's nasal olfactory receptors are different, durian addicts can't help falling in love with the things around them, such as durian candy, durian crisp, durian ice cream and durian egg tart, and feel delicious to fly ~ For those who don't like durian, the taste of durian will be irritating and uncomfortable, making it the "most disgusting" fruit in the world.

It is understood that passengers are prohibited from carrying durian on civil aviation planes all over the world, and durian is also prohibited in some public places in Brunei, Indonesia and Malaysia.

Fourth, durian is so expensive, it is most important to choose a delicious one:

Pinch it. Because durian is a kind of jump fruit, during the ripening process, the background color of fruit thorns will gradually change from green to brown, and the fruit thorns will become soft. When you find that two fruit thorns are easier to pinch and get close to, it means that durian is well cooked.

Smell it. Durian will smell like grass when it is immature, but it will have a strong durian smell when it is mature. So you can smell whether there is a strong durian smell in the long handle of durian root. If there is, durian can be delicious ~

Listen. When durian reaches a certain maturity, there will be a gap between the pulp and shell of durian. Durian can be eaten if there is a hollow sound when knocking on the shell, or if it can make a shaking sound when shaking.

Some people may think that durian with a natural mouth will be better, which is a sign of maturity. In fact, this is not entirely correct. After durian opens its mouth naturally, the pulp is easily infected by microorganisms, but it is easy to deteriorate. Therefore, durian should be eaten as soon as possible after cracking.
