What are the advantages of freeze-dried powder injections? In order to help everyone understand, Medical Education Network has compiled the following:
1, Freeze drying is carried out at low temperatures, making it particularly suitable for many thermosensitive substances. Proteins, microorganisms, and the like will not undergo denaturation or loss of biological activity. Therefore, it has been widely used in medicine.
2, When drying at low temperatures, the loss of some volatile components in the substance is minimal, making it suitable for drying some chemical products, drugs, and food.
3, During the freeze-drying process, the growth of microorganisms and the action of enzymes cannot proceed, thus maintaining their original characteristics.
4, Due to drying in a frozen state, the volume remains almost unchanged, maintaining its original structure and preventing concentration.
5, After drying, the material is loose and porous, appearing as a sponge. After adding water, it dissolves quickly and completely, almost immediately restoring its original properties.
6, Due to the fact that drying is carried out under vacuum with very little oxygen, some easily oxidizable substances are protected.
7, Drying can eliminate over 95-99% of moisture, allowing the dried product to be stored for a long time without spoilage.
