How many years can Dong'e ass hide glue keep for its shelf life

The shelf life of Dong'e ass hide glue is generally 5 years, and the actual storage time is affected by storage conditions, packaging integrity, environmental humidity, light intensity, microbial pollution and other factors.

1. Storage Conditions

The unopened Dong'e ass hide glue can be stored in a cool and dry environment until its shelf life is marked. It is recommended to store it in a dark environment with a temperature of less than 20 ℃ and a relative humidity of less than 60%. High temperature and humidity will accelerate the oxidative hydrolysis of protein and sugar components in ass hide glue, resulting in sticky texture or mildew.

2. Packaging integrity

The shelf life of ass hide glue vacuum packaging is better than that of ordinary packaging. The sealed packaging with aluminum foil lining can effectively isolate oxygen and moisture. If not used in a timely manner after opening, it needs to be stored in a sealed can and put in food desiccant. It is recommended to use it within 6 months after contact with air.

3. Environmental humidity

The humid environment will make ass hide glue absorb moisture, soften or even mildew. During the rainy season in southern regions, special attention should be paid to moisture prevention. It can be placed in a storage box containing quicklime. If white frost appears on the surface, it is considered normal precipitation, but if green mold spots appear, it is not edible.

4. Light intensity

Direct sunlight will accelerate the decomposition of effective ingredients of ass hide glue. The collagen peptide chain in ass hide glue is easy to break under the action of ultraviolet light. It is recommended to use dark glass jars for storage to avoid the reduction of efficacy caused by sunlight.

5. Microbial contamination

The contaminated ass hide glue may deteriorate in advance. If ass hide glue is found to have rancid taste, abnormal wire drawing or moth eaten, it should be stopped even if its shelf life has not expired. Traditional ass hide glue is easier to breed microorganisms because it contains a small amount of water, and modern ass hide glue blocks have better preservation.

The texture change of ass hide glue can be checked regularly when it is stored daily. It is recommended to pack it into small portions for long-term storage, but repeated thawing will affect the quality. Pay attention to observe whether there is abnormal smell before taking. It is not recommended to continue taking ass hide glue after expiration. Keep the container clean when closing with yellow rice wine. Deteriorated ass hide glue may cause gastrointestinal discomfort. People with special physique can consult a traditional Chinese medicine doctor before use, and it is recommended to store ass hide glue in the refrigerator freezer during high temperature in summer.
