Summary

'Golden Delicious' apples (Malus×domestica Borkh.) were either untreated or pressure-infiltrated after harvest with 0, 1, 2, 3 or 4% CaCl2 solutions (w/v) and stored at 0 °C for up to 6 months. The chemical composition of the fruit cortical tissue and cell walls of the 2-4 mm layer under the epidermis was studied. CaCl2 infiltration resulted in an increase in both total and cell wall-bound Ca of the apple tissue during storage, with a maximum reached at 2% CaCl2 for fruit stored 4 or 6 months. Levels of total K and Na, cell wall-bound Mg, sugars, were also monitored. The major changes in the tissue and cell walls occurred after 6 months storage, indicating that this stage was critical for quality maintenance.
