Microwave treatments on the ageing physiology of Dendrocalamopsis oldhami bamboo shoots

    Corresponding author: GU Xiao-ping

Abstract: In order to explore the inhibitory effects of microwave on bamboo shoots aging,and more safety and high-quality fresh-keeping method of bamboo shoots,changes in phenylalanine ammonia-lyase(PAL) activity and acid detergent fiber(ADF) mass fraction of Dendrocalamopsis oldhami bamboo shoots were studied using mid and high intensity microwave for 0(the control),10,20,and 30 seconds with four replication. Results showed that after being treated with mid intensity microwave,PAL activity decreased gradually from 155.4 to 62.0 nkat and after high intensity microwave with increasing times,decreased from 159.4 to 35.7 nkat. There were significant differences(P <0.05) between PAL activity of most shoot samples and the control(except for the sample treated for 10 s with mid intensity microwave). The ADF mass fraction decreased rapidly in the prophase,and was lower when the microwave intensity was stronger and treatment time was longer. All facts showed that the shoot ageing speed was faster in the prophase and slowed with increasing microwave intensities and prolonged time periods. [Ch,4 fig. 1 tab. 14 ref.]
