Freezing and Drying Food

What is the difference between dried fruit and freeze dried fruit?


Wiki User

Dried fruit is made by removing water via warm, dry air in a dehydrator or outdoors on a dry, sunny, hot day.

Freeze dried fruit is processed in a factory in a more involved method whereby a nearly all of the moisture is removed, through a four-step process involving pretreatment, freezing, initial drying and secondary drying stages.

Dried fruit has a shorter shelf life and often has additives to prevent spoilage. Freeze dried fruit, properly stored in sealed containers, may last for decades and requires no further preservatives.
