主 题：Coprinus comatus allyl isothiocyanate postharvest reactive oxygen species metabolism
摘 要：The aim of this study was to evaluate the effect of allyl isothiocyanate(AITC)on the reactive oxygen species(ROS)metabolism and quality of postharvest Coprinus comatus(***).Fresh mushrooms were stored at 4℃with AITC at 5,10,and 20μL/L for 18 d,*** was performed every 3 d,and physicochemical parameters and ROS metabolism related enzymes activities were *** with the control,the application of AITC at 10μL/L significantly(P0.05)decreased xanthine oxidase activity after 9 d of storage,while it significantly(P0.05)improved the activities of succinic dehydrogenase,glutathione reductase,peroxidase,catalase,and ascorbate peroxidase in the middle and later stages of ***,the Ca^(2+)-ATPase and superoxide dismutase activities in sample treated by 10μL/L were all significantly(P0.05)higher than those in the ***,the accumulation trends of malondialdehyde and ROS were retarded and membrane integrity was ***,high-concentration AITC(20μL/L)treatment accelerated the ROS generation and increased electrolyte leakage *** AITC treatments significantly(P0.05)inhibited the respiration rate during the first 9 d of storage and retarded browning of *** during the storage of 18 *** findings suggested that AITC treatment would be a promising method to maintain *** quality,but the concentrations need to be optimized.
