Respiration rates of the slices from the curing treated samples were lower than those of the control slices throughout 12 d shelf life period (Fig. 6). Higher than expected respiration rate was observed immediate after cut and 3 d after cut both in the curing treated and control slices because of the wounding response (Tapia et al., 2008). The results indicate that curing treatments decreased potato respiration rate of fresh-cut potatoes compared to control, which may be related to low metabolism in the tissue and low browning. Our results were consistent with the findings by Zhang, Zhan, Wang, and Tang (2008) in that the respiration rate was proportional to the extent of the browning. Higher respiration rates indicate a faster overall metabolism and deterioration (Chung & Moon, 2009).
