With light colored fruits, you can dip them in lemon juice, but I'm not sure that works with other types of foods. It definitely keeps apples and bananas from getting too dark and unappetizing looking.
We are thinking that we need to start with more fruits, the kids seem to love them and it is something quick that we can take on the go. I absolutely hate eating in the car but this is something that is not really messy so I think we can make it work once we get a little better at it.
I believe you can use lemon juice or apple cider vinegar and achieve the same effect. I don't ever dehydrate fruits that turn brown, so I guess I don't worry too much about it. Does anyone know if you let them soak in it or just kind of dip them in?
I've never tried vinegar, but I don't taste the lemon juice on my banana or apple chips. Stephanie, all I do is a quick dip in the lemon juice. I would think soaking them would make them taste more lemony and make them take longer to dry.
