If you have already opened the sealed bag of freeze-dried powder, it is best to package it in a sealed bag. Place it in a tightly closed plastic bag to prevent the ingress of oxygen and moisture. If you have a vacuum sealer, it is best to use it to maintain the freshness of the freeze-dried powder.
Also, when storing freeze-dried powder, try to avoid exposing it to sunlight, as this will cause loss of quality. Also avoid storing it in an excessively humid or damp environment, as this may cause moisture absorption and deterioration.
If you have a refrigerator, it is a good idea to store the opened freeze-dried powder in a sealed bag in the refrigerator. While freeze-dried powder can be stored at room temperature, the cold and airtight environment of the refrigerator better preserves its freshness.
