    Solution

    Freeze drying, also known as lyophilisation or cryodesiccation, is a low temperature dehydration process that involves freezing the product or moisture on the food, lowering pressure, then removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat.
