Freeze drying strawberries is a method used to remove water content from the strawberries, allowing them to retain their nutritional value, taste, color, and extend their shelf life. The process involves freezing the strawberries and then reducing the surrounding pressure to allow the frozen water in the fruit to sublimate directly from the solid to the gas phase.
