摘要
研究体积分数为3%O2、5%CO2和92%N2的气调处理和不同贮藏温度对黄藤笋生理特性的影响。黄藤笋经气调处理后,分别于8℃和20℃下贮藏,定期测定其褐变度(BD)、呼吸强度、苯丙氨酸解氨酶(PAL)、过氧化物酶(POD)、多酚氧化酶(PPO)和过氧化氢酶(CAT)活性等生理指标。结果表明,气调处理结合8℃的低温贮藏,能显著降低黄藤笋的呼吸强度,抑制PAL、POD和PPO活性的上升,保持CAT的活性,延缓褐变的发生,延长保质期。
At different temperature,the effects were studied of modified atmosphere package(MAP)(3% O2、5% CO2 and 92% N2)on physiological characteristics of daemonorops margaritae shoots.Daemonorops margaritae shoots with controlled atmosphere storage were stored at 8 ℃ and 20 ℃.The changes were determined of browning degree,respiration rate,the activities of phenylalanine ammonia-lyase(PAL),peroxidase(POD),polyphenol oxidase(PPO) and catalase(CAT).The results showed that modified atmosphere package and low temperature(8 ℃) could reduce respiration rate,inhibit the increase of PAL,POD and PPO activity,maintain the activity of CAT,resist browning and prolong the shelf life of daemonorops margaritae shoots.
