Abstract

The respiration rates of fresh shiitake mushroom were measured in modified atmosphere packaging (MAP) with LDPE and PVC films at 0, 5, 15, 20 and 30°C. The results indicated that respiration rates were suppressed by decreasing O 2 and increasing CO 2 concentrations at 5, 15 20 and 30°C, but it was not changed much at 0°C inside both LDPE and PVC packages. The respiratory quotient (RQ) breakpoints were mainly controlled by O 2 concentration and little affected by CO 2 concentration. Moreover, there was temperature dependence of RQ breakpoint for fresh mushroom in MAP with high linear correlation coefficient (r=0.928). In the aerobic respiration period, the respiration rates of fresh mushroom were also significantly affected by O 2 concentration. The effect of the storage time became greater factor next to O 2 concentration at 15 and 20°C. These results suggest that better keeping quality for fresh shiitake mushroom could be obtained from low O 2 atmosphere conditions above RQ breakpoint at low temperature.
