摘要
用4种不同低密度聚乙烯(LDPE)薄膜(0.010,0.025,0.040和0.025 mm+防结露成分)包装菠菜,在低温(2±0.5)℃下进行贮藏试验。通过对贮藏过程菠菜理化指标和贮藏品质的定期测定及效果分析,结果表明:采用0.025 mm的含防结露成分的LDPE包装菠菜,能很好地保持菠菜的新鲜状态,不仅能降低呼吸强度、丙二醛含量和细胞膜透性,而且可控制叶片的叶绿素和可溶性蛋白含量下降,但各厚度薄膜包装对菠菜失水率影响相差不大。
Spinach were packaged with different thickness of polyethylene films （0.010, 0.025, 0.040 and 0.025 mm ＋ anti-condensation component, with no film packaging as control） and stored at （2 ± 0.5） ℃. The physiological and biochemical changes in spinach during low temperature storage were studied. The results indicated that spinach packaging with 0.025 mm＋ anti-condensation component film could maintain the best quality. It not only reduced the respiration rate, MDA content, and cell membrane permeability, but also kept the level of chlorophyll content and protein content in spinach, which resulting in prolong of the storage period and shelf life. However, there was no clear difference in water loss rate in spinach among packaging with different thickness of films.
