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。
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.
