- 摘要:
- 以菠菜为试材，采用10%浓度臭氧处理菠菜，以0.03 mm PE膜包装袋包装（对照组）于(20±1)℃下贮藏，通过对其贮藏期间感官品质及生理指标的测定，研究臭氧对采后菠菜保鲜效果的影响。结果表明：臭氧处理可有效维持菠菜的感官品质，减缓水分散失和丙二醛（MDA）含量的上升程度；此外，臭氧可抑制菠菜叶绿素及维生素C含量的下降，提高其过氧化物酶（POD）、过氧化氢酶（CAT）及抗坏血酸过氧化物酶（APX）的活性，从而达到保鲜效果，延长菠菜的货架期。
- Abstract:
- Taking spinach as test material,the effect of ozone on sensory quality and physiological indexes changes of spinach was studied,the spinach was treated by the concentration of 10% O3,and placed in 0.03 mm PE film with untreated group (control),then stored at (20±1)℃ and the changes of physiological and biochemical were measured.The results showed that 10% O3 treatment effectively maintained the sensory quality of spinach,reduced the weight loss,delayed increasement of malondialdehyde (MDA) content.In addition,10% O3 inhibited the decline of chlorophyll and vitamin C content,enhanced the activities of peroxidase (POD),catalase (CAT) and ascorbate peroxidase (APX).The concentration of 10% O3 resulted an effective method to extend the shelf-life of spinach.
