Enclosures were equipped with valves; facilitating real time monitoring and measurement of oxygen (O2), carbon dioxide (CO2) and ethylene (C2H4), in addition to temperature and relative humidity throughout the treatments. The ripening process was carried out in two stages; an airtight CA and regular air (RA). In the first stage, fruit ripening was initiated while in the second conversion to Rutab stage took place. Accumulated CO2 produced for both cultivars was fairly linear, whereas accumulated C2H4 was linear for “Bronsi” and exhibited polynomial trend for “Taboni” cultivar. However, respiration and C2H4 production rates did not follow specific trends, instead; they exhibited peaks that were very much related to fruit ripening. Time-wise, the first ripening stage lasted 22 hours for both cultivars, but the second stage lasted 23 hours for “Bronsi” and 45 hours for “Taboni”, while ripening percentages for both cultivars exceeded 90% (w/w). Quality attributes such as color (L, Hue angle and Chroma) and sensory attributes (sweetness, taste and acceptance) for CA induced ripened dates were compared with naturally ripe ones.
