摘要： The present study proposed a synergistic method to extend the postharvest quality of straw mushroom (Volvariella volvacea) by controlling the conditions of ultrasound treatment and relative humidity (RH). Results showed that 10-min ultrasound treatment combined with storage at 95% RH prolonged the postharvest quality of straw mushroom from 24 h or 48 h to 72 h. The appearance of straw mushroom was maximally kept with original odor, minimum weight loss of 28.83%, malonaldehyde (MDA) content of 5.06 nmol g(-1), and higher total soluble sugar (TSS) of 28.32 g kg(-1) and total soluble protein (TSP) of 30.27 g kg(-1). The ultrasound treatment also inhibited the browning and respiratory rates via inactivating the browning-related PPO activity to 236.52 U g(-1), and PG1 to 0.038 U g(-1), SDH to 3.62 U mg(-1) Pro, CCO to 9.29 U mg(-1) Pro and G-6-PDH/6-PGDH to 69.87 mu mol NADP g(-1) min(-1) activities of involved in respiratory pathways after 72 h of storage. Our results suggest that ultrasonic treatment with the control of relative humidity could potentially reduce the quality deterioration of straw mushroom.
