Abstract
Summary
Post harvest green bamboo shoots（Bambusa oldhami Munro）are characterized by an increased respiration and browning, storage life were lose in one day under room temperature storage. In this study, the appropriate modified atmosphere packaging condition and storage temperature to extend storage life of green bamboo shoots were investigated. Green bamboo shoots were packed with LDPE bag, after 0℃, 3℃, 5℃ or 10℃ storage, fresh weight, total sugar content, cutting force, total fiber content, color value and browning area were examined, all these results prove that low temperature storage could reduce decay. Sensory evaluation were perfomred after 10 days storage. 0℃and 3℃ storage, it provide better flavor, tender texture and high consumer acceptance. Moreover, the effect of LDPE and PP packaging combined with different package model（air、vacuum）were investigated. Althogh the vacuum packaging could reduce color change and browening, however the atmosphere filtration could not perforem effectivily, result in low O2 （2%）and high CO2 concentration（40%）in bag than cause rapid sugar degradation and off-flavor. On the other hand, air packaging could maintain better flavor and 3℃ storage reduce browning better. Beside, PP packaging was more yellowing than LDPE packaging. The microperforated on package can improve gas excahge, and extend storage life to 15 days. The examination on fresh weight, total sugar content and texture were illustrated that microperforated could maintain better quality, especially with 0.15 mm penetration. In conclusion, package with LDPE bag combine 0.15 mm penetration and store in 3℃ is the best condition of green bamboo shoots storage.
