The shelf life of mooncakes of different brands is different. The longest shelf life is 90 days, the shortest is only a dozen days, and some are marked 45 days or 60 days. According to industry insiders, because mooncakes still retain a certain amount of moisture and oil after baking, the shelf life cannot be as long as biscuits and other dehydrated foods. The length of the shelf life is restricted by many factors such as raw material quality, production environment, production equipment and packaging technology, especially the impact of the production environment and packaging materials on the shelf life. Modern factories operate under sterile conditions, eliminating sources of pollution. Therefore, mooncakes produced and packaged in this environment have a longer shelf life. Although hand-produced products can achieve hygienic conditions, they cannot reach the level of sterility and will be more or less contaminated with bacteria. Therefore, even if the same packaging is used, the shelf life will be shortened. In addition, because the fillings in mooncakes are different, the shelf life is also different. Generally speaking, mooncakes filled with dried fruits have a longer shelf life, while mooncakes filled with egg yolks and fruits have a shorter shelf life, while mooncakes filled with chocolate are best refrigerated. Industry insiders remind consumers that it is safest to eat mooncakes processed in modern factories with advanced equipment. If you choose handmade mooncakes, try to choose fresh products with a relatively recent production date.
