I recently started using a food dehydrator, I have noticed over the coarse of a week or so the fruit is less dry. It's slightly chewy, definatly not like the crispness when originally dried. It tastes fine, but I have no idea what spoiled dehydrated food looks like. - How long will dehydrated fruit last in a jar like this? Bormioli Rocco Italian Fido Glass .5 liter Canning Jars - Do I need to put O2 obsorbers in with the food as we eat it? - Do I need to use a moisture absorbing packet? G.
