Respiration rate of shiitake mushroom in modified atmosphere packages

The respiration rate of fresh shiitake mushroom (Lentinus edodes Sing.) was measured by pouch method at 0, 5, 15, 20 and 30degreesC. The results indicated that respiration rates were suppressed by decreasing O-2 and increasing CO2 concentrations at 5, 15 20 and 30degreesC. The lower oxygen limit (LOL) was mainly controlled by O-2 concentration and little affected by CO2 concentration. Moreover, the LOL was increased with rise in temperature. For the multiple regression analysis, among three factors of the elapsed time, O-2 and CO2 concentrations, the respiration rate was also affected by O-2 concentration markedly.
