Résumé

Changes in the quality parameters of Spanish pomegranates (cv. Mollar) during ripening and 7 weeks of cold storage at 5 deg C and 90-95% relative humidity were studied. Fruit and seed weights and surface colour increased with ripening. Total soluble sugar, pH and titrable acidity did not show significant differences during the weeks studied (from the 26th to 32nd weeks after flowering), but seed colour (Lab values) and juice colour (absorbance at 150 nm) increased during this period, with a maximum during the last 2 weeks. These results indicate that pomegranates should be harvested during the 31st to the 32nd weeks after flowering in order to get the best pigmentation without a decrease in other quality parameters. The study supports the theory that pomegranate is a non-climacteric fruit and that pomegranates can be stored for at least 45 days without deterioration in fruit quality.
