Vitamin C in stored apples
I have a number of desert apple trees and attempt to store the apples
in the garage during the winter.Many of the apples become soft (as compared with crisp),but still taste wonderful.In our family,we eat lots of apples,both for their pleasant taste and since we think that they keep us healthy.Does anyone know whether apples kept in this way retain their vitamins (especially Vitamin C) in anything like the original fresh value?
