Study the effect of temperature and slicing on respiration rate of peeled carrot

Modified atmosphere packaging is one of the recommended methods to increase the shelf time and quality of fruits and vegetables. To design a good packaging، accurate respiration rate is necessary. In this research، selection of the proper mathematical equation in determining the respiration rate is investigated and respiration rate of peeled and ready to use carrots were measured at laboratory temperature (21±1°C) and refrigerator temperature (7±1°C) in the closed system. In addition، effects of temperature and slicing were studied on respiration rate were studied. It was found both increase in temperature and slicing، increase the respiration rate. Results of this research are necessary to design of modified atmosphere packaging.
