01
What kind of strange fruit is jackfruit?
Jackfruit is a tropical fruit, also called wood pineapple, native to southern India, the mainland introduction of jackfruit has a history of more than a thousand years, mainly in the southern region of the mainland, such as Guangdong, Hainan, Fujian, Yunnan and other places are planted, of which Hainan is the largest jackfruit planting area in the mainland. The fruit is divided into "dry buns" and "wet buns", the former is crisp and crisp, and the latter is soft and sticky.
The first feature of jackfruit is that it is large.
Jackfruit trees are between 2-3 meters tall and have large fruits – in fact, jackfruit is the heaviest fruit in the world, weighing up to 59 kilograms, almost equivalent to the weight of an adult.
The apple fell from the tree and smashed Newton's genius idea, a story known to everyone (although it was made up...). But if Newton was hit by jackfruit...
There have indeed been accidents in life where people have been hit by jackfruit, the victim fainted on the spot and was unconscious, was sent to the hospital ICU for treatment, and only after waking up did he know that fortunately the perpetrator was only a 10-pound "underage" jackfruit. If this is a mature jackfruit, the consequences are unimaginable.
The second characteristic of jackfruit is stickiness.
Jackfruit is not only heavy, it also has a hard and rough shell, there is a sticky liquid after opening the shell, which increases the difficulty of handling jackfruit, often there are food video bloggers who challenge to tear jackfruit by hand, often are vicious expressions, desktop is messy, this is probably why buy the whole jackfruit cheap, and buy disassembled jackfruit expensive.

The slime of this sticky hand and sticky knife is actually a weapon used by jackfruit to protect itself, the main ingredient is polysaccharide, the texture is viscous, and the lower the temperature, the more sticky [1]. It can be washed with hot water soaking, or it can be scraped with plastic gloves or plastic bags while handling. Experienced people will also brush the knife with a layer of oil to separate the mucus, and then wash the knife with oil afterwards to avoid opening a jackfruit to scrap a knife.
No wonder some netizens commented:
If you love someone, give him a box of jackfruit.
Hate a person, give him a jackfruit.
02
Is jackfruit related to durian and pineapple?
Seeing the name jackfruit, some people will think of pineapple and think that the two of them should be a bit of a "entangled" relationship.
In fact, the two of them really have nothing to do with each other, but they are a bit similar in name. Jackfruit came to China during the Wei and Jin Dynasties, and pineapple came from the American continent after it crossed the sea, originally called pineapple, it is said that because it looks like jackfruit produced in the southwest of the mainland, it later has the name of pineapple.
In addition, some people feel that jackfruit and durian are vaguely related, because they are both so big and ugly, and they are often sold together.
The two are actually not related, can only say that the appearance is similar, durian is the mallow family (some sources are written in the Kapok family), jackfruit is mulberry family. [2] And durian is a single fruit, while jackfruit is a polymer fruit, and there are many independent small fruits when opened.

Why is jackfruit so fragrant? What's the nutrition?
Many friends like jackfruit because of its attractive aroma, there are studies on 4 different genotypes of jackfruit in the aroma components of the analysis, the results of a total of 66 aroma components identified, of which ethyl butyrate, isobutyl butyrate, isobutanol, methyl butyrate, butyl acetate and other 16 substances are the main aroma components of jackfruit. [3]

Jackfruit not only tastes delicious, but also has good nutrition! Its most prominent nutrients are rich in the minerals potassium, polysaccharides, and carotene.
(1) The potassium content of jackfruit is 330 mg/100 g, which is 1.3 times the potassium content of the bananas we often eat. For small partners who need to control blood pressure, it is still relatively friendly.
(2) Jackfruit is rich in polysaccharides, and in vitro studies have shown that jackfruit polysaccharides have a strong antioxidant effect, which can scavenge free radicals and reduce the risk of disease. And animal experiments have shown that jackfruit polysaccharides can improve immunity and induce the secretion of tumor necrosis factor (TNF-α), γ interferon (IFN-γ) and interleukin-1β (IL-1β). [4]
(3) Jackfruit is rich in carotene, which is the coloring substance of jackfruit pulp. In terms of content, the red flesh is more than the yellow flesh, which is beneficial for the health of the eyes. Therefore, compared with yellow meat, the nutritional value, appearance quality and flavor taste of jackfruit varieties of red meat have more market advantages. [5]

Don't lose the core of jackfruit, you can eat it!
Don't look at a jackfruit is quite large, in fact, 1/3 of its volume is the core, that is, the seed part of jackfruit. When many people eat jackfruit, they will throw away the core directly, which is a pity!
Figure: Reference 4
The core of jackfruit can not only be eaten, but also a treasure part of jackfruit, very nutritious! It can be seen from the data that the nucleus of jackfruit is not only high in protein and low in fat, but also rich in dietary fiber, which can enhance satiety, prevent constipation, and be beneficial to intestinal health. [6]
Some people also measured the mineral content in the jackfruit core, and found that its potassium content is very rich, compared with the Xishuangbanna jackfruit core, the potassium content of the Hainan jackfruit core is more advantageous. [7]
In addition, it has also been found that jackfruit kernels also contain functional factors γ-aminobutyric acid, with a content of up to 413.76mg/100g, which has the functions of promoting memory and relieving fatigue. [6] There are also many health supplements related to γ-aminobutyric acid ingredients on the market, mainly advertising their effects on relieving stress and promoting sleep.
Therefore, don't throw the core of the jackfruit when eating jackfruit in the future, you can cook it directly with salt water, the taste is powdery, a bit like a chestnut. It can also be cooked with rice, jackfruit core lysine content is rich up to more than 1%, and grain lack of lysine, the two can form nutritional complementarity, improve protein absorption and utilization. The author also personally challenged a jackfruit nuclear rice for this article, in addition to the shell is a little difficult to go, it really tastes like a chestnut, it is worth a try.

These 3 types of people eat jackfruit to pay attention
Although jackfruit is both nutritious and delicious, there are 3 types of people to be cautious and not greedy!
a) Obese people: Jackfruit is high in calories and carbohydrates, nearly 2 times that of apples. 100 grams of jackfruit (about 5 pitted cloves) has a calorie of 105 kcal, which is almost equivalent to a small bowl of cooked rice. If you eat too much, you will grow meat properly.

b) Diabetic people: Jackfruit has a postprandial blood glucose GI value of 75 [8], which is a high-GI food and is not friendly to people who need to control blood sugar. If you really like to eat, it is recommended to eat it at a meal instead of some staple foods, and at the same time with vegetables and protein foods, you can delay blood sugar after meals.
c) People with high uric acid: jackfruit contains high fructose, and excessive fructose intake will increase uric acid levels and induce gout.
Summary:
Although jackfruit is delicious, but the calories and sugar content are not low, if you want to be healthy and not fat, you must control, don't be greedy!
