One step closer to maximum efficiency

The moisture content of home-dried fruit should be about 20 percent. When the fruit is taken from the dehydrator, the remaining moisture may not be distributed equally among the pieces because of their size or their location in the dehydrator.

Does dried fruit have more water than fresh fruit?

Is dried fruit as healthy as fresh produce? ... As dried fruit contains less water and is, therefore, a more concentrated source of nutrients, it tends to be higher in most vitamins and minerals per 100g when compared to their fresh counterparts. It is also significantly higher in calories per 100g
