Durian is a tropical fruit that usually ripens at room temperature. Putting durian in refrigerator will make it hard, but will not make it ripe. On the contrary, cold storage will slow down the ripening speed of durian, because low temperature will slow down the metabolism of fruit. If you want to make durian more mature, you should put it at room temperature until the pulp becomes soft and has a strong aroma. If you want to keep the durian for a longer time, you can put it in the refrigerator, but it should be noted that the taste and taste of durian may be affected. Therefore, it is best to mature durian at room temperature, and then put it into the refrigerator before eating.
