摘要: 以新鲜的“蜜本”南瓜为试验材料,研究可食性多功能防腐保鲜膜对鲜切南瓜的保鲜效果。将经切割后的南瓜用不同保鲜膜包裹处理,测定其硬度、弹性、咀嚼性、黏性、乙烯释放速率、丙二醛(MDA)的变化,探讨不同保鲜膜处理对鲜切南瓜的质地和生理生化代谢的影响。结果表明:不同保鲜膜处理能不同程度地保持鲜切南瓜的质地,延缓乙烯释放量的增加,减小MDA积累;其中,2号保鲜膜(主成分为壳聚糖、海藻酸钠、丁香油等)处理效果最好,有效地提高了鲜切南瓜贮藏期间的品质,并延长了其货架期。

Abstract: The present study aimed to evaluate the fresh-keeping effect of two types of edible multi-purpose preservative films (prepared mainly with chotisan and sodium alginate in the presence and absence of clove oil) on fresh-cut ‘Miben’ pumpkin. Fresh-cut ‘Miben’ pumpkin was coated with different films, and then stored at low temperature. Textural properties, ethylene production, and MDA content in fresh-cut pumpkin were determined during storage period. The results indicate that the two types of edible preservative films could obviously maintain textural properties, reduce MDA accumulation, and delay ethylene production in fresh-cut pumpkin. The edible film consisting of chotisan, sodium alginate and clove oil was more effective in maintain storage quality of fresh-cut pumpkin and prolonging its shelf-life.

Key words: preservative film, fresh-cut pumpkin, storage
