Can I still consume powdered donkey-hide gelatin that has been stored for 8 years?

Generally speaking, it is not recommended to consume powdered donkey-hide gelatin (Ajiao) that has been stored for 8 years. Detailed explanations are as follows:

The shelf life of powdered Ajiao is influenced by multiple factors, including storage conditions and whether the packaging has been opened. Under normal storage conditions, unopened powdered Ajiao typically has a shelf life of 1–3 years. However, even within its expiration date, improper storage, such as exposure to high temperatures, humidity, or direct sunlight, may cause the powder to deteriorate and shorten its shelf life.

Powdered Ajiao stored for 8 years has likely exceeded its normal shelf life. After expiration, the powder may exhibit signs such as layering, clumping, discoloration, or moisture absorption. The active ingredients may have degraded, reducing its efficacy, and harmful substances may have formed. Consuming expired powdered Ajiao not only fails to achieve the expected health benefits but may also burden the gastrointestinal system and potentially cause gastrointestinal inflammation or other health issues.

In daily life, it's important to purchase and store food and health products properly, avoiding long-term storage to ensure food safety.
