Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process [1] that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. [2] . This is in contrast to dehydration by most conventional methods that evaporate water using heat. [3]
Jan 30, 2024 · Freeze-drying is a form of dehydration that removes a product’s water content by turning it from ice to vapor. The three-step process preserves a product’s nutritional value, taste, and...
Aug 11, 2024 · Freeze-drying – or lyophilisation, from the Greek lyo (release) and philia (love) – is a process of dehydration used to preserve delicate materials or make them easier for transport. An item to be preserved is frozen, and then put into a low-pressure environment with heat applied to the area to enable the frozen water in the object to sublimate.
Freeze drying (also known as lyophilization) is a water removal process typically used to preserve perishable materials, with the goal of extending their shelf life and/or preparing them for transport.
to preserve something, especially food, by freezing and then drying it: When herbs are freeze-dried, the oils in them are kept intact. The Quecho Indians even developed a method of freeze-drying wild potatoes to provide food throughout the winter months. I freeze dry the flowers and then frame them. Fewer examples.
The meaning of FREEZE-DRY is to dry (something, such as food) in a frozen state under high vacuum especially for preservation. How to use freeze-dry in a sentence.
The fundamental principle in freeze-drying is sublimation, the shift from a solid directly into a gas. Just like evaporation, sublimation occurs when a molecule gains enough energy to break free from the molecules around it.
Freeze-drying, or lyophilization, is like "suspended animation" for food. You can store a freeze-dried meal for years and years, and then, when you're finally ready to eat it, you can completely revitalize it with a little hot water.
