Nobody likes biting into an apple and getting a mouthful of mush.
Fortunately, that doesn't happen too often. They make sure we consumers get only the finest, crispiest apples. Some go to food processing plants for making juice or other tasty products like apple sauce. Still, a few mushy apples seem to find their way into mom's fruit basket. Part of the reason is because distributors don't have a fast, gentle method of checking individual apples on their way to market, processing or storage.
