Bamboo shoots were packaged in CPE bags with different gas ratio, i. e. ,O2(2%)+CO2(5%)+N2(93%),O2 (80%)+CO2(5%)+N2(15%) and O2(80%)+CO2(20%). The preservation effect of different modified atmospheres on fresh bamboo shoots was studied. Water loss, L value, conductivity, polyphenol oxidase (PPO) activity, peroxidase (POD) activity, ascorbic acid content, and sensory index were determined. The results indicated that water loss, the change of L value and conductivity, the activity of PPO and POD, and sensory change were the lowest in the package with O2(80%)+CO2(20%), in which bamboo shoots were still of good quality with high level of ascorbic acid content after 15 days of storage.
