Vacuum freeze-drying（FreezeDrying，FD）Fruit and vegetable crisps have a high retention rate of nutrients and bioactive substances, while also maintaining the color and fresh flavor of fruits and vegetables. The process of freeze-drying apple slices generally includes: cleaning → peeling and removing the core → cutting and color protection → vacuum freeze-drying (pre freezing sublimation drying analytical drying) → packaging. Pre freezing is a process in vacuum freeze-dryingimportantThe freezing state and ice crystal morphology of fruits and vegetables in the processFDThe quality of fruits and vegetables has a significant impact. Pre freezing and freeze-thaw treatment not only affect the drying rate of apple slices, but also alter their sensory qualities such as hardness and brittleness. Taking into account the quality of vacuum freeze-drying apple slices and drying energy consumption, slow freezing is recommended（XXCombined with freeze-thaw cycles (℃)XThe drying time of vacuum freeze-dried apple slices can be shortened to600Within minutes.
