Usually, home made iced mooncakes can be kept for about three days. Although the iced mooncakes sold in stores can have a shelf life of 180 days, it's not the same as the ones we make ourselves. The chilled mooncakes we make ourselves are not vacuumed at first, so they are always in contact with air and can be kept for about three days without spoiling, which is the limit. If home made mooncakes do keep for a few days, they must be treated specially. For example, they can be kept in the refrigerator for about a week, but no more than three days at room temperature. And iced mooncakes that have been unwrapped and left for more than two hours will become soft and deformed. This kind of mooncake likes cool, so the preservation is usually accompanied by ice packs, which can extend the shelf life.
