Generally speaking, the shelf life of unopened moon cakes is 2~9 days. The shelf life of moon cakes is mainly affected by the stuffing inside and also by the packaging.

Moon cakes filled with fruit can only be kept for about one month, while those filled with sweet sugar such as bean paste and red dates are slightly longer. Among them, frozen moon cakes have the shortest shelf life, only 15 to 2 days, and they need to be kept in the refrigerator for so long.

The opened moon cakes can only be kept for a few hours at room temperature, and can only be kept for about two days in the refrigerator. Therefore, it is best to eat the opened moon cakes as soon as possible.
