You can experiment with the seasonings in several ways. For example, pumpkin pie spice or chai spice would be a delicious alternative to cinnamon during fall. You could also experiment with cocoa powder. For caramel apple chips, dip them in some brown sugar before dehydrating them. If you use fairly tart apples and want to sweeten them, simply toss the slices with sugar (or a sugar alternative) before dehydrating them.
