In the past, the shelf life of moon cakes was mostly 60 days to 90 days. This year, due to the restrictions on the use of additives, the shelf life of moon cakes on the market is generally shortened, and moon cakes with a shelf life of 30 days to 60 days are more common. Due to the restriction of additives, the shelf life of large manufacturers is generally shortened. With the decrease of additives, the perishable degree of different fillings determines the shelf life of moon cakes. Therefore, there is a phenomenon that the shelf life of different moon cakes varies greatly. General water-based fillings, such as bean paste fillings, have low oil content, so the shelf life is relatively short; And fillings with high sugar content, such as moon cakes filled with various fruits, will have a longer shelf life. In addition, Cantonese moon cakes contain more oil and have a longer shelf life, while traditional Chinese moon cakes contain less oil and have a shorter shelf life.
The shelf life of moon cakes is set by the manufacturers themselves. Generally, regular manufacturers will produce some products for testing before mass production to detect the reproductive ability of bacteria, and then actually observe the deterioration time of moon cakes, so as to determine a safe shelf life. However, for a long time, some small manufacturers did not do any experiments, added a lot of preservatives and marked the shelf life at will.
The shelf life of Wuren moon cakes is generally about 3 months.
Even if there is a shelf life of three months, it is recommended to eat it within one month.
