- 摘要:
- 以菠菜为试材,采用纳米膜(银系列)包装的方法,研究其对菠菜采后贮藏品质的影响。结果表明:在(20±1)℃贮藏,纳米膜包装有效维持菠菜在贮藏期间的感官品质、色泽和失重,延缓叶绿素和维生素C含量的降低,抑制丙二醛(MDA)含量的积累,同时增强了抗坏血酸过氧化物酶(APX)、过氧化物酶(POD)和过氧化氢酶(CAT)活性,减轻了活性氧对组织的损伤。因此,纳米膜(银系列)包装可有效地保持菠菜采后贮藏品质。
- Abstract:
- Spinach was taken as test material,the effect of nano-film (silver series) packaging on the storage quality of postharvest spinach.The results showed that nano-film packaging effectively maintained the storage quality,color and loss weight during the storage period at (20±1)℃.The decrease of chlorophyll content and vitamin C content were delayed and the accumulation of MDA content was inhibited.Meanwhile,the antioxidant enzyme activities of ascorbate oxidase (APX),peroxidase (POD) and catalase (CAT) were enhanced and the damage of reactive oxygen species was reduced.Thus,the nano-film packaging could effectively maintain the storage quality of postharvest spinach.
