薄膜包装对鲜切芹菜抗氧化活性的影响
Influence of film packaging on the anti-oxidation of fresh-cut celery
摘要
Abstract
To study the effects of different film packaging on fresh-cut celery (Nanjing estate parsley) antioxidant capacity,two films (P1-12.75 μm and P2-32.70 μm polyethylene bags) were used for celery storage at the environment of (7 ± 1)℃ and 80% ~90% relative humidity,12.75 μm perforated polyethylene bags was used as a control (CK).The results showed that fresh-cut celery superoxide dismutase (SOD) activity decreased; catalase (CAT) activity firstly increased and then decreased; peroxidase (POD) activity increased slowly during early storage,late occurred peak which indicating celery accelerated aging.Compared with the control,film packaging improved the DP-PH,superoxide anion radical (O2-·),hydroxyl radical (· OH) scavenging activity and CAT,POD activity.P2 film packaging also delayed the accumulation of malondialdehyde (MDA),decrease of SOD activity and POD activity peak occurred.It indicated that the film packaging can effectively retard the aging process of fresh-cut celery.Furthermore,P2 film packaging had better results.关键词
