Vinegar doesn't make apples brown; in fact, it does the opposite. Vinegar is acidic and helps prevent browning. Apples brown when cut due to a reaction between apple enzymes and oxygen. Applying vinegar (which contains acetic acid) deactivates these enzymes, slowing down the browning process. For best results, briefly dip apple slices in a mixture of water and vinegar.
