Why does the surface of an apple appear white and blotchy?

Rating: 90

Sometimes when apples that have been waxed are washed, the surface becomes white and blotchy and looks like the waxy coating has been removed in some places and not in others. This will happen when there is an immediate change in temperature, from a refrigerated apple to a cool sink of water. There is nothing wrong with the apple except the appearance. You can limit this change by washing refrigerated stored apples in a warm diluted saltwater solution and then rinsing in clear water. Apples stored at room temperature should not have as much blotching occur upon washing.
