Whether mooncakes can be consumed after being stored for 5 months depends on the specific conditions. If the mooncake has a longer shelf life, is stored in a cool, ventilated environment, and has not exceeded its expiration date after 5 months, and if there are no visible changes in color, taste, or texture upon inspection, it can be safely consumed.
However, once the mooncake exceeds its shelf life, or if it is observed to have darkened in color, developed green mold spots, grown fuzz, has a texture that is too hard or too soft, or has a sour or bitter taste, such mooncakes should not be consumed. This is especially true for snowy skin mooncakes and fresh meat mooncakes, as they have a relatively shorter shelf life and are more prone to spoilage. At this point, not only will the taste of the mooncake be greatly reduced, but its nutritional value will also be compromised. Consuming severely spoiled mooncakes could lead to nausea, abdominal pain, diarrhea, and other gastrointestinal discomforts, or even food poisoning, requiring prompt medical attention.
To avoid spoilage of mooncakes, it is recommended to purchase or make them as needed, and to refrigerate any uneaten portions in a timely manner, or store them in a cool, dry, well-ventilated place. Additionally, regularly check the shelf life of the mooncakes and pay attention to any changes in taste and color to prevent spoilage.
