This is a guide about drying apples in a dehydrator. Dried apple slices make a delicious healthy snack. Rather that buy them at the market, if you have a dehydrator, they are easy to make at home.
Whether you are drying apples in an oven or in a dehydrator, is it necessary to put lemon juice on the fruit to prevent the apples from browning from oxidation?
Yes, either lemon juice or sodium bisulfite. I use 1 tsp of sodium bisulfite to 1 quart water. I soak the apples in the solution for about 2 minutes. I run the soak process with two batches going. While one is soaking i am laying out another. I switch the oldest back to the front each time i empty a batch. I lay out my apples on a sheet from my excalibur dehydrator. Then i sprinkle a sparse breeze of cinnamon sugar over the apple sheet and stick in the dehydrator. Takes about 10-12 hours. If you save them in a food saver, when they are dried, they will last quite awhile. My kids love them so much i have not had the opportunity to test how long 'awhile' is. I also do the very, very popular pineapple rings!
I came into a bunch of Granny Smith Apples and I want to dry them in my oven. I am not sure how to do this and what temp to set the oven on and for how long. Any advice would be nice.
Usually when I am drying anything in the oven, if it is fruit or deer jerkey, I dry items for about 24-48 hours on the lowest setting my oven has. I have an electric oven so it is about 200 degrees. I place aluminum foil directly on the racks and then place what ever it is that i want to dry. About ever 8 hours i turn it over. Most stuff is done within 24 hours. I also have made fruit roleups this way just pouring the puree into an aluminum pan. Hope this helps
When I dry any thing in the oven it is put on the lowest setting, then I take an oven mitt fold it in half an put it between the door and the oven to let out the moisture.
