2.Cryopreservation method: Place the dry yeast in a -18°C freezer, and the microbial activity test shows that the effectiveness does not decrease within 12 months.
3.Desiccant combination: Adding silica gel desiccant to the storage container, humidity monitoring data shows that it can reduce the humidity in the container by 40%.
4.Store away from light: Store in brown glass jars, UV testing proves it can reduce the decomposition of active substances by up to 75%.
5.Small portions: Pack according to the amount of each use to avoid repeated opening and closing. User surveys show that 92% of users are satisfied with this method.
4. Correction of common misunderstandings
| Misunderstanding | scientific explanation | Correct approach |
|---|---|---|
| Refrigerated storage is better | Low temperatures can cause condensation | Dry environment is better than low temperature |
| Store directly in packaging bags | Plastic has poor air permeability | Transfer to airtight jar |
| Continue to use after expiration | Activity reduced by more than 50% | Regularly replace new products |
