Questions & Step-by-Step Solutions
What is the purpose of lyophilization in downstream processing?
Step 1: Understand that lyophilization is a process also known as freeze-drying.
Step 2: Recognize that this process involves freezing the product first.
Step 3: After freezing, the water in the product is removed by turning it into vapor without going through a liquid phase (this is called sublimation).
Step 4: The removal of water helps to prevent spoilage and degradation of the product.
Step 5: Finally, the product becomes stable and can be stored for a long time without losing its effectiveness.
