Introduction
In general, it is not recommended to consume Tremella (silver ear fungus) one month past its expiration date. Check the shelf life when purchasing and choose products from正规 channels. Store in a sealed container in a dry, cool, and well-ventilated place, avoiding damp environments that may accelerate spoilage. Even if not expired, discard the product if any abnormalities such as clumping, stickiness, unpleasant odor, or darkening in color occur—do not take the risk of consuming it.
Generally, it is not recommended to consume silver ear fungus (tremella) that has been expired for one month. The detailed explanation is as follows:
After being expired for a month, silver ear fungus has significantly lost its nutritional value and can no longer provide the original health benefits. More importantly, expired silver ear fungus is prone to breeding harmful microorganisms such as mold. Toxins produced by mold, including aflatoxin, are highly toxic and may irritate the gastrointestinal tract upon consumption, causing acute poisoning symptoms such as nausea, vomiting, abdominal pain, and diarrhea. Long-term intake may also damage organs such as the liver and increase health risks. Even if there are no obvious signs of mold or unusual odors, microbial contamination cannot be ruled out; therefore, it is not advisable to consume it.
When purchasing, always check the expiration date and choose products from reputable sources. Store in a sealed container in a dry, cool, well-ventilated place, avoiding humid environments that accelerate spoilage. Discard the product even before expiration if clumping, stickiness, off odors, or darkened color occur. Never consume it with the hope of侥幸 (taking chances), to ensure food safety.
