Contact SupplierFreeze-dried pineapple is a popular snack that has been subjected to a freeze-drying process. Freeze-drying is a preservation technique that involves removing the water content from the fruit while maintaining its nutritional value, flavor, and texture.
During the freeze-drying process, fresh pineapple slices are frozen and then placed in a vacuum chamber. The chamber’s low pressure causes the frozen water within the pineapple to undergo sublimation, which means it transitions directly from a solid state to a gas without passing through the liquid phase. This process helps retain the fruit’s original shape and cellular structure.
