| 目的 探究适用于娃娃菜采后贮藏保鲜的包装材料。方法 采用4种不同厚度的聚乙烯薄膜（10，20，30，40 μm）包装娃娃菜，以市场销售的原包装薄膜为对照，测定在常温(23±2)℃下贮藏28 d的品质变化，之后以筛选出的薄膜材料为研究对象，进一步分析其对娃娃菜采后贮藏品质的影响。结果 与其他薄膜包装相比，厚度为30 μm的聚乙烯薄膜包装材料对娃娃菜的保鲜效果最好，其可溶性糖、蛋白含量分别为13.49 mg/g，3.79 mg/g，MDA的质量摩尔浓度为1.51 μmol/g。与对照组相比，厚度为30 μm的薄膜包装能够有效抑制娃娃菜表面菌落总数的生长，延迟腐烂现象的发生，维持其组织较高的抗坏血酸、总酚、可溶性糖、总硫苷和萝卜硫素含量。主成分法综合评价的结果也显示，厚度为30 μm的薄膜包装对减缓娃娃菜品质劣变的效果更理想。结论 厚度为30 μm的聚乙烯薄膜包装能更好地维持采后娃娃菜的贮藏品质，适宜用作采后娃娃菜的包装贮运材料。 |

| The work aims to explore the packaging materials suitable for storage and preservation of postharvest brassica pekinensis. The brassica pekinensis was packaged with four polyethylene films of different thickness (10, 20, 30, 40 μm). With the original packaging film sold in the market as the control, the quality changes after storage at (23±2)℃ for 28 days were measured. Then, the selected films were used as research objects to further analyze their effects on the quality of postharvest storage of brassica pekinensis. Compared with other film packaging, the 30 μm thick polyethylene film packaging material had the best preservation effect on the brassica pekinensis, and the soluble sugar, protein and MDA content were respectively 13.49 mg/g, 3.79 mg/g and 1.51 μmol/g. Compared with the control group, the 30 μm thick film packaging could effectively inhibit the growth of the total number of bacterial colonies on the surface of the brassica pekinensis, delay the occurrence of decay, and maintain high content of ascorbic acid, total phenols, soluble sugars, total glucosinolates and sulforaphane. The results of comprehensive evaluation by principal component method also exhibited that the 30 μm thick film packaging had a better effect in slowing down the deterioration of brassica pekinensis. The 30 μm thick polyethylene film package can maintain the storage quality of postharvest brassica pekinensis in a better way and it is the suitable material for packaging, storage and transportation of postharvest brassica pekinensis. |
