No matter how fresh an apple is, once sliced and oxygen hits the flesh, it starts to oxidize and turn brown, all you need to do is soak the apple slices with a little acidulated water before storing the slices in a sealed container to stop the browning. ‘Acidulated’ describes water that’s been made slightly acidic, you can make your own acidulated water by adding 1 tablespoon of lemon juice to 1 cup of water. You also can make acidulated water by adding lime or pineapple juice even crushed vitamin C tablets.
