Imagine biting into a freeze-dried apple slice; it’s light and crispy, unlike the chewy texture of a dehydrated one. That’s because the freeze drying process has preserved the integrity of the fruit’s structure. Additionally, the cellular structure preservation in freeze drying helps foods retain their original form and taste more effectively than other drying methods.
