Freeze drying is a dehydration process that involves freezing a substance, reducing the pressure around it, and then removing the ice by sublimation. Sublimation is the transformation of a substance directly from a solid to a gas, skipping the liquid phase. This unique method helps preserve the product's original properties, making it a popular choice for preserving perishable goods.
