The aim of this study is to determine the C.A. storage conditions that can preserve better the organoleptic attributes of quince (Cydonia oblonga Miller, Rosaceae family), depending on the level of CO2. The three quince cultivars studied were 'Ekmek’, 'Bereczki’ and 'Tinella’, monitored for 350 days. The samples were stored in C.A. conditions with: T: 1°C, RH: 95%, O2-3% and different levels of CO2, in the Research Center for Studies of Food Quality and Agricultural Products, of the UASMV Bucharest. The following physiological and biochemical measurements: respiration and transpiration rate, maturity index, ascorbic acid content, were compared with organoleptic attributes. After 350 days of storage, from obtained results it was observed a decrease of the ascorbic acid content between 51,4% (for 'Tinella’ cv. in 5% CO2) and 70% (for 'Ekmek’ cv. in 5% CO2). For respiration rate were observed increases between 85% (for 'Ekmek’ cv.in 2% CO2) up to almost 3 times (for 'Tinella’ cv. in 0% CO2), between the initial and final moments. As expected, the CO2 content preserved better the quality of quinces compared with control (0% CO2), based on the results obtained from the sensory analysis.
