FOOD DARKENS
The temperature is too high.
FOOD DOESN’T DEHYDRATE
Usually, it is due to poor air circulation. It can also be because the pieces are too large or dried at too high a temperature, causing skin to form on the food.
VERY LONG DEHYDRATION TIME
Stir during drying and ensure good air circulation.
UNEVEN DRYING
The pieces are not evenly cut or your oven/food dehydrator does not dry evenly. Try to rotate the tray/drying racks.
Here are some solutions to a few of the most common problems you may experience when dehydrating foods.

FOOD ONLY DRIES ON THE SURFACE
The drying temperature is probably too high. High temperature causes a skin to form on the food, preventing moisture from escaping.
POTATOES TURN BROWN
Not blanched.
FISH OR MEAT DOESN’T BECOME DRY
It’s probably due to large pieces of fatty meat.
MUSHROOMS TURN BLACK
They have probably been spoiled due to poor air circulation or they may have been frozen before they were picked; discard the mushrooms.
