In order to explore the effect of ultrasound (US) treatment on the storage quality of Lyophyllum decastes, the sensory quality and energy metabolism-related enzyme activities of the fresh mushroom were measured after US treatment (at 35 kHz frequency and 300 W power) for 10 min. The results showed that US treatment could maintain a higher level of brightness (L* value) and higher contents of total protein (TP), ascorbic acid (AsA), and glutathione (GSH), and increase the activity of total superoxide dismutase (T-SOD), as well as significantly reduce the degree of browning compared to the untreated control group. The contents of adenosine triphosphate (ATP), nicotinamide adenine dinucleotide phosphate (NADPH), and oxidized?NADPH (NADP+) were higher in the US treatment group, and so was the activity of glucose-6-phosphate dehydrogenase (G6PDH), H+K+-ATPase, Na+K+-ATPase, and Ca2+Mg2+-ATPase, indicating that US treatment could slow down the quality deterioration of L. decastes. Therefore, US can be used for the preservation of postharvest edible fungi.
