Introduction of Lyophilization:
Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase.
The advantages of lyophilization include:
- Low temperature drying could maintain microbial activity and make sure protein invariance. So it is particularly suitable for bioactive products of thermal instability, biochemical products, genetic engineering products, blood products, etc.
- Low temperature drying greatly reduces the loss of volatile components,heat-denatured nutrients and aromatic components in material. Therefore that's best drying method for chemicals, medicines and foods.
- During the drying process, the growth of microorganisms and the action of enzymes are almost impossible, and the physical properties are best maintained.
- The sealed material after drying is convenient to store long time at room temperature.
- Rapid and easy dissolution of reconstituted product.
The combination of low pressure and low temperature induces a phase change called sublimation, which turns a solid state of material (like an ice crystal) immediately into a gaseous state (like water vapor). That sublimated water vapor is pulled by the vacuum into a colder condensation unit. What's left is a freeze-dried flower, herbs, vagetables, fruit and medicines that retains its taste, color, and shape.
