Can I still eat mooncakes that are one month past their expiration date but show no signs of spoilage?

Generally, even if mooncakes are still intact one month after their expiration date, they are not recommended for consumption. Expired food poses potential safety risks, and unless under exceptional circumstances, eating expired products is not advised. The detailed explanation is as follows:

Mooncakes contain high levels of oil, sugar, and starch. After being expired for a month, even if there is no visible mold or unusual odor, harmful bacteria or molds invisible to the naked eye may have already grown inside. These microorganisms can produce toxic substances that may cause gastrointestinal discomfort such as abdominal pain, diarrhea, and vomiting after consumption. Particularly due to their high sugar and fat content, mooncakes may deteriorate faster than their outward appearance suggests.

The nutritional value of expired mooncakes gradually degrades, and their texture deteriorates as well—becoming dry, hard, greasy, or losing flavor. Additionally, some mooncakes may be exposed to dust or bacterial contamination due to inadequate packaging seals, further increasing health risks. Even heating or cooking cannot completely eliminate these harmful substances.

To store mooncakes properly, always follow the shelf-life instructions on the packaging, keeping them in a cool, dry place or refrigerated to prevent moisture absorption or exposure to direct sunlight. It is best to consume mooncakes within their expiration period. If already expired, regardless of appearance, they should be discarded immediately—do not take the risk.
