Preservation method of freeze-dried powder:

Freeze-drying is an effective method to dry heat-sensitive products and substances that need to maintain biological activity. This method is to freeze the water contained in the product to be dried at low temperature, and then dry it in a vacuum environment, so that the water can be directly sublimated from the solid state to steam and removed from the product, so that the product can be actively dried.

This method can effectively prevent the change of physical and chemical characteristics of the product, and has little damage to the structure and characteristics of biological tissues and cells, so that they can quickly enter the dormant state, effectively protecting the stability of effective components of many heat-sensitive pharmaceutical biological products.

Such as protein, microorganisms will not denature and lose their biological activity; Secondly, the shape of freeze-dried products is loose after drying, and the color is basically unchanged. After adding water, they can be dissolved quickly, and the physical and chemical characteristics and biological activity of the original aqueous solution can be restored.

Because drying is carried out in vacuum, it has a good protective effect on some easily oxidized substances. Moreover, the moisture content of the freeze-dried product is very low, which improves the stability of the product, reduces the chance of pollution, facilitates transportation and prolongs the shelf life of the product.
