| 中文摘要: |
| 为探讨适合西兰花的自发气调包装材料，用 0.02 mm 的双向拉伸聚丙烯（BOPP）、聚丙烯（PP）和聚乙烯（PE）薄膜对西兰花进行自发气调包装，5益下贮藏 30d。结果表明，3 种自发气调包装处理不同程度地改善西兰花的保鲜效果。 其中，BOPP 包装的保鲜效果最好，贮藏 30d 仍有较高的质量属性和外观属性，叶绿素、维生素 C、可溶性糖、可溶性蛋白等营养物质均保持较高的水平，同时霉变率、切口褐变率、MDA 和相对电导率处于最低水平。 PP 包装效果次之，PE 包装效果较弱。 因此，BOPP 适宜作为采后西兰花的自发气调包装材料。 |
| 英文摘要: |
| The effects of different modified atmosphere packaging(MAP) on the broccoli (Brassia oleracea L. var. Italica) quality maintenance by comparison with non-wrapped broccolis were studied. Broccoli heads were packaged using three types of film in thickness of 0.02 mm, biaxially oriented polypropylene (BOPP), polypropylene (PP) and Polyethylene (PE), and then stored at 5for 30 d. The results revealed that three MAP improved the quality of broccoli after 30 d storage. BOPP films showed the most effective on broccoli preservation with high quality and appearance attributes, maintaining high contents of vitamin C, chlorophyll, soluble sugar and soluble protein, while keeping low mildew rate, browning rate, relative conductivity and MDA content in broccoli heads. PP films showed good effect but PE films a relatively weak effect. Therefore, BOPP could be selected as the broccoli MAP films. |
