Understanding Freeze-Dried and Dehydrated Fruits

Definition of Freeze-Dried Fruits

Freeze-dried fruits undergo a sophisticated process called lyophilization. This involves freezing the fruit and then placing it under a vacuum. This vacuum allows the frozen water content in the fruit to sublimate—that is, turn from a solid directly into a vapor—thus removing almost all moisture while preserving the structure of the food. The result is a lightweight, non-perishable product that retains most of its original nutrients and flavor. This method not only extends the shelf life of fruits significantly but also maintains their texture and taste, making them an ideal choice for long-term storage and convenience.
