Apple (Malus domestica Borkh.) fruits are commonly
stored for long periods at low temperatures under
controlled atmosphere. Fruit quality and nutritional value
decreases during storage. The shelf-life of apples is
affected by a number of factors, such as growing,
harvesting operations or storage conditions (Soliva-
Fortuny et al., 2002). Losses in fruit quality are mostly
due to its relatively high metabolic activity during storage
(Fattahi et al., 2010). Calcium (Ca2+) has been
extensively reviewed as both an essential element and its
potential role in maintaining postharvest quality of fruit
