What is the difference between freeze-dried liquid and freeze-dried powder?

Form, storage and use, application fields and other differences.

1, form: freeze-dried liquid refers to the liquid that is directly freeze-dried during freeze-drying, and the final product is in solid form. Freeze-dried powder refers to the freeze-dried product which is transformed into powder by crushing or other methods after the liquid is frozen in the freeze-drying process.

2. Storage and use: Freeze-dried liquid and freeze-dried powder have different storage and use due to their different forms. Freeze-dried liquid should be stored at low temperature to prevent it from dissolving into liquid again. When in use, the freeze-dried solution should be re-dissolved into liquid state. Freeze-dried powder is already in powder form, so it is easier to store and use, and no additional dissolution step is needed.

3. Application field: Freeze-dried liquid and freeze-dried powder are also different in application field. Freeze-dried liquid is used for products stored in liquid state. Freeze-dried powder is more suitable for products that need long-term storage and are easy to carry and use.
