The purpose of this experiment was to determine if controlled atmosphere apple storage would affect the amount of malic acid and starch levels in apples. I became interested in this idea when one day I bit into an apple and it was crisp, mild, smooth and tart, while a week later the same batch was grainy and had a not-so-good taste.
