FREEZE DRY Meaning and
Definition
-
Freeze drying, also known as lyophilization, is a process used to remove the moisture from a substance while preserving its structure, nutritional value, and overall quality. It involves freezing the substance at extremely low temperatures and then subjecting it to a vacuum, which causes the frozen water to undergo sublimation, transforming directly from a solid to a gaseous state without passing through the liquid phase. Through this process, freeze drying aims to retain the original properties of the substance, such as taste, texture, color, and aroma.
The freeze drying process consists of several steps. First, the substance is frozen quickly to ensure the formation of small ice crystals. Next, the vacuum is applied to create a low-pressure environment, causing the ice to vaporize and escape as water vapor, leaving behind a freeze-dried product. Lastly, a controlled warming phase is implemented to remove any remaining frozen water molecules without allowing the substance to rehydrate. The resulting freeze-dried product is lightweight, easily reconstituted with the addition of liquid, and has an extended shelf life due to the absence of moisture, which prevents the growth of microorganisms and the deterioration of the product.
Common applications of freeze drying include preserving foods, pharmaceuticals, and biological materials. The process is widely used in the production of instant coffee, ready-to-eat meals, freeze-dried fruits and vegetables, as well as in the pharmaceutical industry for the production of vaccines, enzymes, and antibiotics. Freeze drying has become a valuable technique for preserving and storing various substances while maintaining their integrity and properties over long periods.

Etymology of FREEZE DRY
The word "freeze dry" is a combination of two distinct terms, "freeze" and "dry".
The term "freeze" comes from the Old English word "freosan", which means "to freeze or become stiff with cold". Its origin can be traced back to the Proto-Germanic word "freusanan" and the Proto-Indo-European word "preus-" both meaning "to freeze" or "to frost".
The term "dry" comes from the Old English word "dryge", which means "free from moisture or wetness". It also has Proto-Germanic and Proto-Indo-European roots with similar meanings.
When these two terms are combined in the phrase "freeze dry", it describes a specific process of food preservation.
