The effect of time and temperature on the respiration rate (RR) of fresh-cut produce is critical towards the development of a suitable modified atmosphere packaging (MAP) system. This requires an adequate mathematical model for prediction of RR as a function of both time and temperature. This study investigated the effect of temperature (5, 10 and 15 °C) and storage time of 1 to 5 days on the RR (RO2 and RCO2) of two pomegranate cultivars (cv. „Bhagwa‟ and„Ganesh‟) fresh arils. RO2 and RCO2 were within the range of to ml/ and to ml/, respectively for both cultivars. RO2 and RCO2 were3-4 folds significantly higher with increased temperature from 5 to 15°C, reducing storage temperature of arils from 15 to 5°C decreased RO2 and RCO2 by about 67 and 70%, respectively. | Effect of time and temperature on respiration rate of pomegranate arils cv.
