摘　　要：为探究高阻隔性薄膜包装对贮藏期间油菜品质和叶绿素降解的影响,采用3种高阻隔性的薄膜(P1、P2和P3)包装油菜,于(4±1)℃条件下贮藏,分析油菜表型、袋内气体成分、色泽、营养品质和叶绿素衍生物的变化。结果表明:与对照相比,高阻隔性薄膜包装可以减缓油菜的品质劣变进程及叶绿素降解,其中高阻隔性薄膜P1和P2可以维持袋内低O_(2)高CO_(2)的环境,显著抑制油菜L、a和b的升高,减缓类胡萝卜素、叶黄素、抗坏血酸和可溶性蛋白含量的下降,维持较高的叶绿素衍生物(叶绿素a、叶绿素b、脱植基叶绿素a、脱植基叶绿素b、脱镁叶绿素a和脱镁叶绿酸a)含量,在货架30 d时总叶绿素含量分别比对照组高0.37 mg/g和0.40 mg/g,从而延缓了叶片黄化衰老。结论:高阻隔性薄膜P1和P2可以维持油菜较高的品质,抑制叶绿素降解,延长贮藏保鲜期15 d以上。The aims of this study was to investigate the impact of high barrier film packaging on quality and chlorophyll degradation of Brassica campestris L.Brassica campestris L.was packaged using three different high barrier films(P1,P2,and P3)and then stored at(4±1)℃.The changes of phenotype,oxygen and carbon dioxide in the bags,color,nutritional quality and chlorophyll derivatives of Brassica campestris L.were analyzed.The results indicated that compared with the control group,the high barrier film packaging could slow down the quality deterioration and chlorophyll degradation of Brassica campestris L.The high barrier film P1 and P2 packaging could maintain the low O_(2) and high CO_(2) environment in the bag,significantly inhibit the increase of L^(*),a^(*) and b^(*),and slowed down the decrease of carotenoid,lutein,ascorbic acid and soluble protein contents.The content of chlorophyll derivatives(chlorophyll a,chlorophyll b,chlorophyllide a,chlorophyllide b,pheophorbide a and pheophytin a)was maintained at a high level,the total chlorophyll content was 0.37 mg/g and 0.40 mg/g higher than that of the control group at 30 days of shelf life,respectively.thus delaying leaf yellowing and senescence.In general,high barrier films P1 and P2 could maintain high quality of Brassica campestris L.,inhibit chlorophyll degradation and prolong the storage life for more than 15 days.
