Abstract:This paper investigated the effect of transport vibration time on the quality and cell wall metabolism of fresh Lycium barbarum，with fresh L.barbarum′Ningqi No.7′as the research object.The vibration frequency was set at 3 Hz，and the vibration time was 4，8，12 h and 16 h separately（no vibration was used as the control group）.After vibration，the sample was stored at 4 ℃.Changes in hardness，respiration，cell wall components and related enzyme activities of fresh L.barbarum during different storage periods were determined.The results showed that vibration accelerated the quality deterioration and cell wall degradation of fresh L.barbarum.Compared with the control group，the 16 h vibration group had decreased hardness of fresh L.barbarum（P＜0.05），increased respiration（P＜0.05），increased soluble pectin and cellulose（P＜0.05），and enhanced activities of cellulase，polygalacturonase and pectinesterase（P＜0.05）.Therefore，the longer transport vibration time resulted in the deeper mechanical damage of fresh L.barbarum，faster cell wall metabolism，and more serious softening，thus accelerating its quality deterioration.
