Raw durian will mature in 2-7 days. If it is at room temperature, the durian that looks green on the outside will be ripe in 1 to 2 days, that is, it is ready for consumption. However, some friends like durians to be ripe enough to open their mouths, so it will take more than 4 days. As long as it is properly protected, it won't break. But the weather is hot, so everyone should be careful not to let the durians get exposed to the sun. This is not good for the durians. Generally, the durians should be wrapped in old newspapers to preserve them. If you are in a hurry to eat durian, you can buy a ripe banana or a relatively ripe apple and put it together with the durian. The fruit will release ethylene gas to ripen the durian. Another method is to wrap the pulp in plastic wrap and store it in the refrigerator. It can usually be eaten within 2 days. Wrapping the durian in old newspapers can also make the durian ripen faster, but it must be wrapped and placed in a cool place to prevent the durian from spoiling.
