FREEZEDRIES Meaning and
Definition
-
Freezedrying is a process of preserving food or other perishable substances by rapidly freezing it and then removing the water content through sublimation. Also known as lyophilization, this technique involves freezing the material at a very low temperature under vacuum conditions. It is commonly used to extend the shelf life of various food items, pharmaceuticals, and biological samples.
During the freezedrying process, the material is first frozen solid to a very low temperature. Then, the surrounding pressure is reduced, causing the frozen water within the substance to transition from a solid to a gas state through sublimation. This process bypasses the liquid phase, allowing the water to transform directly into vapor without passing through the liquid phase in which spoilage and degradation may occur.
The benefits of freezedrying include significantly prolonging the preservation period of various substances while maintaining their original taste, texture, and nutritional value. It ensures that the product's integrity and quality are preserved, as well as its weight and volume, which are reduced due to the removal of water content.
Freezedried products are typically lightweight, have a long shelf life, and are easy to rehydrate, making them convenient for transportation, storage, and usage. They are commonly found in the form of powdered or granular substances, ranging from fruits, vegetables, and meats to coffee, tea, and even emergency ration kits.
In conclusion, freezedrying is a preservation technique that involves freezing and removing water content through sublimation to maintain the quality, taste, and nutritional value of different substances while prolonging their shelf life.

Etymology of FREEZEDRIES
The correct term is actually "freeze-dried", not "freezedries". Nonetheless, the etymology of the word "freeze-dried" can be broken down as follows:
1. Freeze: This term comes from the Old English word "freosan" and Middle English word "frozen", meaning "to become or cause to become solid by cooling to below zero degrees Celsius (32 degrees Fahrenheit)".
2. Dry: This word comes from the Old English word "drȳge", which means "free from moisture, not wet". It has its roots in Proto-Germanic and Proto-Indo-European languages.
When combined, "freeze-dried" refers to a process whereby food, substances, or other perishable items are frozen and then subjected to a vacuum environment where ice is directly lyophilized (converted from solid state to gaseous state), avoiding the liquid phase altogether.
