question re: mold and drying foods

[Guest guest]

I would like to preserve wild rosehips, which are now in abundance in the

mountains around here. Does anyone know the best way to do so to make sure there

is no mold? In the past, I left them out to air dry and some of them tasted

moldy.

I could use a dehydrator. Anyone know about whether this decreases the chance of

molds? Or any other ideas? I have candida issues, so can't preserve them in

vinegar...

Thanks!!
