Why do some apples shrivel in storage and how can it be prevented?

Some apple cultivars shrivel during cold storage which is cultivar dependent.  One of the most common cultivars that this is a problem with is golden or yellow delicious due to a thinner layer of natural wax on the apple surface called the cuticle.  This natural wax is what causes apple to shine when rubbed on a cloth (“buffing”).   Although the apples are edible after shriveling, with pretty good flavor, it can be easily prevented.  Placing the apples in a plastic bag loosely sealed during refrigeration will minimize the moisture loss and extend the storage life and firmness of the apples.
