Study on Preservation Effect of Chitosan on Cucumber

XIAO Long-yun et al (College of Biological and Environmental Engineering,Jiangsu University of Science and Technology,Zhenjiang,Jiangsu 212018)  
[Objective] The aim of the study was to seek a good biological preservation method of cucumber.[Method]The changes of postharvest physiology and sensory qualities were investigated to evaluate the preservation effect of chitosan on cucumber.[Result]During the period of storage,compared with the control,the organic acid contents,Vc contents,chlorophyll contents,soluble sugar contents were significantly increased and the weight losses significantly decreased.The differences between the different chitosan concentrations were highly significant.The treatment with 1% chitosan coating showed the best preservation effect than the other treatments.Organic acid contents,chlorophyll contents,soluble sugar contents and Vc contents increased respectively on the forth days by 48.7%,43.0%,23.9% and 37.6%,on the eighth days,by 76.9%,58.5%,75.0% and 103.9%,on the twelfth days,by 111.8%,92.8%,290.3% and 246.5%.The weight losses on the forth,eighth and twelfth days respectively decreased by 63.8%,63.4% and 63.2%.At the same time,good senses of cucumber could be maintained.[Conclusion]Chitosan was safe and effective biological preservation agent.
