低温寒害对香蕉果皮褐变度、电导率及相关酶活性的影响
[目的]探索低温处理对香蕉果皮褐变度、电导率和PPO、POD活性的影响,以及褐变度与电导率、酶活性之间的关系。[方法]选择未受寒的桂蕉6号香蕉生果,经不同低温处理后,检测果皮褐变度、电导率、PPO活性、POD活性。[结果]对香蕉果实只进行低温处理,当达到一定的低温及处理时间果皮出现褐变,随着处理温度的降低、时间的延长,电导率增大,PPO、POD活性呈先下降后上升趋势。低温处理后再常温放置12 h,经11℃及以下低温处理的香蕉果皮均出现褐变,各处理间电导率差异较小,PPO、POD活性随处理温度的降低、时间的延长呈上升趋势。[结论]香蕉果实经11℃以下低温处理一定时间,果皮容易出现褐变,低温处理后...

| Abstract_FL | [Objective] The study aims to explore the effects of low temperature treatments on browning degree,electric conductivity,PPO astivity and POD activity of banana peel,and the relationship between them.[Method]Unchilled immature banana Guijiao No.6 were treated with different low temperatures,then the browning degree,electric conductivity,PPO activity and POD activity of peel were tested.[Result] The browning of peel occurred when temperature was below certain degree and lasted a certain period of time.With the decrease of the treatment temperature and prolonging of the treatment time,the electric conductivity increased,the activities of PPO and POD decreased firstly and then increased.When the bananas were treated with low temperature at different time and then placed at room temperature for 12 h,the browning of peel occurred with temperature below 11 ℃.The electric conductivity of different treatments varied slightly.The activities of PPO and POD showed an upward trend with the decrease of treatment temperature and prolonging of treatment time.[Conclusion] Treated under the temperature of 11 ℃ for a certain period of time,the banana peel was prone to browning.Moreover,banana was placed at room temperature after the low temperature treatment,the browning of peel became severe.The browning degree was positively related to the activities of PPO and POD.The electric conductivity of peel increased due to low temperature treatment,and it returned to normal after being placed at room temperature. |
