L-Ascorbic acid contents and other quality criteria in apples (Malus domestica Borkh.) after storage in cold storage and controlled atmosphere.

Fruits of 5 apple cultivars harvested in September/October 1996 in Norway were stored for up to 3 months in air storage (2-3 deg C, 90% RH) and for up to 6 months in controlled atmosphere (CA) storage. Cultivars Summerred, Lobo, Mutsu and Akero were stored in 3% O2 + 1% CO2 at 3 deg and cv. Aroma was stored in 2% O2 + 0.5% CO2 at 2 deg . After storage the fruits were held for one week at room temperature (approx. 20 deg ), simulating shelf life conditions. Ascorbic acid contents (vitamin C) and other quality criteria such as water loss, firmness, soluble solids and titratable acidity were measured after storage and after the simulated shelf life period. Fruit quality retention was better in CA storage than in air storage. Ascorbic acid loss was greater in CA than in air storage, albeit over a longer period.
