Résumé

The effect of different storage conditions on the development of anaerobic metabolites and sugars and acids as well was investigated with sweet cherry fruit (Prunus avium L.). Three sweet cherry cultivars (Karesova, Kordia and Vanda) were stored in ultra-low oxygen (ULO), anaerobic conditions (AN) and regular atmosphere (RA), respectively. Juices were then produced and analysed. The effect of anaerobic conditions caused a remarkable production of ethanol. Exposing the fruit from ULO and AN to air resulted in a decrease in ethanol of one-third after 30 days, but ethanol contents were still higher than in fruit stored under RA conditions. At an informal tasting carried out during fruit quality evaluation, no noticeable off-flavour was detected in the fruit. The effects of treatment and storage time on firmness of the skin and flesh were studied by means of the Anova test. A decrease in firmness was not significantly affected by the oxygen content in the different storage atmospheres and results were comparable for ULO and AN treatment. In fruit of all cultivars, statistically significant breakdown of acids (citric acid and malic acid) occurred; gas mixture of storage and subsequent aerating phase had an influence on the acid concentration.
