Whole apples stored at room temperature are best quality for a few days. Apples kept in the refrigerator in a crisper drawer or open plastic bag are best quality for up to 6 weeks.
Apples that are starting to shrivel can be used in cooking.
Apples tend to brown after they are peeled or cut. Browning is not harmful. To keep cut apples looking fresh for a few hours, dip the cut pieces in lemon or orange juice and refrigerate in a covered container or closed plastic bag.
Refrigerating cut apples in a container of water also keeps them white, crisp, and ready to eat.
