What Is Freeze Drying, and How Does It Work?
Freeze drying removes about 99% of the water while the food stays frozen, which is why it keeps texture, flavor and nutrition for decades.
Freeze drying, also called lyophilization, is a way of preserving food that removes about 99% of its water while the food stays frozen the entire time. The process happens in three stages: first we freeze the food well below zero, then we apply a vacuum so the ice changes directly from solid to vapor, skipping the liquid state, and finally we draw out the last traces of moisture.
In our workshop in Coronado Town Center, a full cycle typically runs between 20 and40 hours, depending on what we load, how wet it is and how big the pieces are. During that time the machine holds a careful balance of temperature and pressure, so the food keeps its cellular structure intact.
That is why freeze-dried strawberries still taste like fresh strawberries and turn soft again in minutes when you add water. Because the water is simply gone, the bacteria, molds and enzymes that normally spoil food have nothing to work with. Sealed properly, that is how food reaches those 25+ year shelf lives.
The same technology that goes into astronaut food is sitting right here in Coronado. And because the finished pieces are bite-sized and incredibly light, they are perfect for camping, boating, hiking and emergency kits across Panama.
