In this study, the effects of different treatment times (40, 50, 60 s) on the changes of physicochemical properties and enzyme activities of postharvest fresh-cut Dendrocalamus brandisii (D. brandisii) shoots during storage were investigated using dielectric barrier discharge-cold plasma (DBD-CP). The results showed that DBD-CP improved the brightness of fresh-cut D. brandisii shoots with the highest contents of total phenols, total flavonoids, soluble proteins, and soluble sugars compared with CK group. At the 30th day of storage of CP1, CP2, and CP3-treated D. brandisii shoots, peroxidase activity decreased by 11.13, 15.96, and 5.03 U/g (P<0.05), polyphenol oxidase activity decreased by 0.28, 1.21, and 0.62 U/g (P<0.05), phenylalanine deaminase activity decreased by 1.99, 7.19, and 5.81 U/g (P<0.05), 4-coumaroyl-coenzyme A ligase activity decreased by 3.17, 4.41, and 1.81 U/g (P<0.05), pectin content increased by 23.61%, 58.33%, and 44.44% (P<0.05), and cumulative synthesis of cellulose and lignin decreased by 7.81, 37.24, and 13.86 mg/g (P<0.05), 0.54, 0.68, and 0.55 mg/g (P<0.05), respectively. Principal component analysis showed that CP2 had the smallest confidence circle, indicating that it had the best quality stability of D. brandisii shoots. This study provides some theoretical basis for the application of DBD-CP technology in the field of postharvest preservation and processing of D. brandisii shoots.
