Durian is a tropical fruit. With the rapid development of modern logistics industry, it often appears in supermarkets, fruit stores and other sales places, and is gradually accepted by more and more people. In order to help consumers eat, buy and store durian scientifically, the following consumption tips are specially made.
What is Durian?
Durio zibethinus Murr, also known as Shaozi and civet fruit, belongs to the genus durian in the kapok family of Malvaceae. Durian has a long growth cycle and takes 4-8 years to bear fruit. It is mainly planted in Southeast Asia, and also in some parts of southern China. The average temperature of the growth environment is above 22 ℃, which is generally available from May to August. Durian on the market is mainly imported.
Durian fruit is oval, light yellow or yellow green. The outer part has conical thick spines. The pulp is rich in protein, fat, vitamins, minerals, flavonoids, polyphenols and anthocyanins. Because it contains diallyl trisulfide and other sulfur compounds, it has a strong smell. The taste is soft and delicate, known as the”king of fruits”. Common durian varieties include Golden Pillow, king of Cat Mountain, tommany, etc. In addition to fresh food, it can also be made into durian dried durian, durian powder and durian sauce, as well as deeply processed durian desserts and beverages.
Purchase of Durian
Consumers should buy durian through formal channels. If purchasing imported durian, you need to pay attention to the origin, source, inspection and quarantine certificate of Inbound Goods, nucleic acid test certificate, disinfection certificate and other information. Avoid purchasing and overseas shopping, and do not buy imported durian from unknown sources. When selecting durian, pay attention to the following points:
Smell. Smell it near the bottom of durian reliably. Mature durian has a strong smell. If you smell wine, durian may have gone bad; If you smell the smell of fresh cut grass, it means it is not mature enough.
Look at the appearance. Generally speaking, durian of the same variety has larger mature fruit grains, which are relatively yellow in color, light yellow or dark yellow. If the color is blue or green, it indicates that it is not mature enough.
Pinch a sharp thorn. Hold the tips of the two adjacent thorns with your hands and close inward. If you pinch them easily, it indicates that durian is ripe. If it is difficult to pinch and feels solid, it indicates that it is not completely cooked. Pay attention to safety when pinching with your hands and be careful to prick your hands.
Look at the cracking degree. If there are some tiny cracks on the top of the fruit and a strong smell can be smelled at the same time, it indicates that durian has high maturity. It is not recommended to choose durian with large cracks, because it is impossible to confirm whether the pulp is contaminated.
Shake the pulp. Gently pick up the durian and shake it gently with your hand after holding it firmly. If you feel a slight collision inside, or there is a slight sound, it means that the pulp has matured and separated from the shell, otherwise it is relatively raw.
 Storage of Durian
Natural storage. The unopened durian should be stored in a cool and ventilated place. The immature durian can be wrapped in newspaper or cloth, put together with apples, bananas and other fruits, and stored in a cool place. It ripens faster.
Refrigerate or freeze storage. After the durian is opened, the pulp needs to be packed with fresh-keeping film/bag/box, and put into the refrigerator at about 4 ℃ for cold storage, generally not more than 2 days. It can also be frozen at -18 ℃ for a long time. Durian will have the taste of ice cream after freezing. When eating again, you should pay attention to check whether it has gone bad. If you smell sour or alcohol, don’t eat it.

Eating Durian
There is a saying on the Internet that”Durian with milk has poisoned Cobra”, which believes that eating both together will produce caffeine, leading to caffeine poisoning, soaring blood pressure and sudden death of heart disease. In fact, durian and milk do not contain caffeine, so it is impossible to produce caffeine when eaten together. The two are also common collocations in desserts and cold drinks, such as durian milkshakes, durian milk, etc.
Peel durian before eating. First, cut the raised part at the bottom of durian with a knife, and you can see the lines inside. Then cut a line along the lines with a knife, and then peel off the durian shell, take out the pulp, and you can eat it. Durian should not be eaten too much at a time. Special groups such as diabetes, kidney disease,”one old and one young” should pay attention to the following points:first, durian has high sugar content, and people with diabetes and hypercholesterolemia should eat less; Second, durian has a high potassium content, so people with kidney disease and heart disease should eat less; Third, durian pulp is sticky, which is easy to block the throat and trachea and cause suffocation. The elderly and children should eat less and slowly, and people with colds, coughs, and trachea sensitivity should not eat it.
