The Science of Freeze-Drying: Creating Crispy, Shelf-Stable Arabic Bread

Arabic bread, most commonly known as pita or khubz, is a soft, slightly leavened flatbread. When freeze-dried, almost all the moisture is removed through a process called “Lyophilization”. The bread is frozen, and then placed in a vacuum where the ice sublimates directly from solid to gas.
The result is a very light, crispy, and porous version of the original bread that has an extremely long shelf life and retains most of its original nutrients and flavor once rehydrated.
