Question

Freeze drying is also known as

• A. Crystallization
• B. Gelatinization
• C. Homogenization
• D. Lyophilization

Hint:

\textbf{Lyophilization} is the technical synonym for freeze-drying. It's a key process for preserving sensitive materials like vaccines, pharmaceuticals, and high-quality instant coffee.

Answer 1

The Correct Option is D

Step 1: Define Freeze Drying.
Freeze drying is a dehydration process that involves freezing the product, lowering the pressure, and then adding heat to allow the frozen water in the material to sublime directly from the solid phase to the gas phase.

Step 2: Define the given options.
Crystallization: The process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.
Gelatinization: The process of breaking down the intermolecular bonds of starch molecules in the presence of water and heat.
Homogenization: The process of reducing the size of particles in a liquid to make it uniform and stable.
Lyophilization: This is the scientific term for the freeze-drying process. "Lyo" means solvent and "phil" means loving, referring to the ease with which the dried product reabsorbs water.
