| 英文摘要 | 以"南芋一号"为材料,研究了贮藏期内不同处理的菊芋块茎在不同温度下菊粉含量及多酚氧化酶、过氧化氢酶活性的变化。结果表明:在保藏的0~15d,对照(CK)处理菊芋在室温下菊粉含量较高,15d后于-2℃菊粉含量居高;贮藏期间多酚氧化酶(PPO)和过氧化氢酶(POD)活性均于-2℃最低。1.0%壳聚糖处理的菊芋块茎在贮藏期内均于室温下菊粉含量维持较高水平,PPO活性于-2℃最低,POD在5℃活性最低;1.5%壳聚糖处理在贮藏期内于10℃下菊芋块茎菊粉含量较高,在-2℃下PPO和POD活性较低。在贮藏期内,1.0%壳聚糖处理在各温度下菊粉含量明显提高,PPO活性最低;1.5%壳聚糖处理POD在各温度下... |
| 中文摘要 | The changes of inulin content and the activities of enzymes （such as PPO and POD） of Jerusalem artichoke （Nanyu 1） following chitosan amendment was studied during a 30 day storage period at 10 ℃, 5 ℃, -2℃ and ambient respectively. The results showed that, the inilun contents in the samples of the treatment of control （CK） were higher than others at ambient during 0-15 days, and the contents of inilun were the highest in the samples stored at -2 ℃ after 15 day, the activities of both PPO and POD were the lowest at -2 ℃ in the storage period. Treatment with 1.0% chitosan coating rised the contents of inilun higher at ambient, and reduced the activities of PPO and POD at -2 ℃ and 5 ℃ respectively. Treatment with 1.5% chitosan coating rised the contents of inilun in the samples higher at 10 ℃, and reduced the activities of PPO and POD at -2 ℃. During the storage period, treatment with 1.0% chitosancoating rised the contents of inilun of JAT higher, and reduced the activities of PPO lowest at 10 %;, 5 %, -2 %; and ambient respectively, and treatment with 1.5% chitosan coating reduced the activities of POD lowest. |
