Salt water prevents apples from browning due to its ability to reduce the exposure of apple flesh to oxygen and slow down the oxidation process, which is responsible for browning. Saltwater also inhibits the activity of polyphenol oxidase, the enzyme involved in the browning reaction. Simply soaking apple slices in a saltwater solution for a few minutes before serving can keep them looking fresh longer.
