摘要: 采用聚乙烯(polyethylene,PE)、聚偏二氯乙烯(polyvinylidene chloride,PVDC)、低密度聚乙烯(low-density polyethylene,LDPE)、线性低密度聚乙烯(linear low-density polyethylene,L-LDPE)4 种不同材质的保鲜膜以及气调包装结合硅藻土附载丁香酚缓释处理对草莓进行包装处理,研究草莓4 ℃贮藏期间品质的变化。结果表明:不同保鲜膜以及气调结合丁香酚缓释处理能不同程度地抑制草莓腐烂以及质量的损失,延缓可溶性固形物、可滴定酸、还原糖以及VC的流失,抑制丙二醛含量的上升以及超氧化物歧化酶、过氧化物酶活力的下降;其中以气调包装结合丁香酚缓释处理效果最佳,PVDC结合丁香酚缓释处理其次,其能将草莓货架期分别延长至15 d和12 d。本实验结果可为草莓的保鲜提供参考。

Abstract: Strawberry fruit were packaged with polyethylene (PE), polyvinylidene chloride (PVDC), low-density polyethylene (LDPE), linear low-density polyethylene (L-LDPE) or modified atmosphere packaging (MAP) combined with eugenol-loaded diatomite treatment. The quality changes were monitored during subsequent storage at 4 ℃. The results showed that all four treatments could inhibit strawberry decay and mass loss in varying degrees, retard the loss of soluble solids, titratable acids, reducing sugar and VC, and suppress the increase of malondialdehyde (MDA) content and the decline of superoxide dismutase (SOD) and peroxidase (POD) activity. Among them, MAP combined with eugenol-loaded diatomite treatment was the most effective, followed by PVDC combined with eugenol-loaded diatomite treatment, which could prolong the shelf life of strawberry to 15 and 12 days, respectively. The results of this experiment can be useful for the preservation of strawberry fruit.
