Do not smother unripe durians in plastic bags.

Many people believe that if the durian is not completely ripe, you can put it into a plastic bag and then tie the bag tightly, so that the durian can ferment in the bag and gradually become soft and sweet. However, this method is very dangerous. Because durian will release a lot of gas during the fermentation process, if the mouth of the bag is too tight and the gas cannot be discharged, it will cause the bag to explode, and may even cause a fire or explosion accident. In addition, if the durian has started to become moldy, suffocating it in a plastic bag will allow the mold to multiply in the bag.

If you want to preserve durian, it is best to place it in a well-ventilated place away from direct sunlight. If the durian is already ripe, you can put it in a plastic bag and refrigerate it in the refrigerator to extend the shelf life of the durian. If the durian is not ripe yet, you can leave it at room temperature and wait for it to ripen naturally. If you want to speed up the durian's ripening process, place it next to a ripe banana or apple, which will speed up the durian's ripening process.

How to choose durian

1. Skin color: The skin color of durian is mainly earthy yellow and covered with irregular brown protrusions. The yellower the color of the skin, the more mature the durian is and the sweeter it tastes. But be aware that if the outer skin turns green, it means the durian is immature and has a lighter taste.

2. Fruit petal thickness: The greater the thickness of durian petals, the plumper pulp. Generally speaking, durians with a petal thickness of more than 4 centimeters are of higher quality.

3. Shell weight: The weight of durian shell is generally between 3-5 pounds. If two durians are of the same size, the heavier they are, the more pulp they have and the higher their value.

4. Thorn density: The higher the density of durian thorns, the more delicious the pulp is. Generally speaking, durians with thorn density between 2-3 cm are of better quality.

5. Shell integrity: The higher the integrity of the durian shell, the fresher the fruit. If the fruit shell is damaged or cracked, it is likely to contaminate the pulp and affect the taste.

6. Smell: Durian has a unique smell and rich aroma. If it smells rotten or has other peculiar odors, it means the fruit has gone bad and should not be purchased.

7. Sound: When selecting durian, you can tap the shell gently. If you hear a solid sound, it means the pulp is full. If you hear a hollow sound, it's likely that the pulp has shrunk or gone bad.

8. Judgment of ripeness: When buying durian, you can ask the merchant when the fruit will be picked. The general maturity time is 10-15 days after the stems drop. In addition, the ripeness of the fruit can also be judged by the dryness of the durian stem. If the stem is green and moist, it means the fruit is immature; if the stem is dry and yellow, it means the fruit is mature; if the stem falls off, it is likely that the fruit is overripe or spoiled.
