摘要: 以羧甲基纤维素钠(CMC-Na)为涂膜材料,探究在不同质量分数的涂膜液处理下光皮木瓜(Chaenomeles sinensis)的贮藏保鲜效果,包括光皮木瓜的质量损失、维生素C含量、有机酸含量、总糖含量、黄酮含量以及总酚含量随时间的变化,以期获得羧甲基纤维素钠涂膜液的最佳处理浓度,从而延长光皮木瓜的货架期,为光皮木瓜的产业化提供参考。结果表明,CMC-Na涂膜处理能够有效减轻光皮木瓜贮藏过程中的质量损失,可以抑制有机酸、总糖、黄酮、总酚的减少和维生素C的降解。所有处理中1.0%质量分数的CMC-Na涂膜处理保鲜效果最好,可有效地延长光皮木瓜的保鲜期。

Abstract: In this study, sodium CMC was used as coating material to investigate the effects of coating solution on the storage and preservation of Chaenomeles sinensis, including the time-dependent change of mass loss, VC content, organic acid content, total sugar content, flavonoids content and total polyphenols content. In order to obtain the optimal treatment concentration of CMC-Na and extend the shelf-life of Chaenomeles sinensis, to provide references for the industrialization of Chaenomeles sinensis. The results showed that CMC-Na film could effectively reduce the mass loss of Chaenomeles sinensis during storage, inhibit the decrease of organic acid, total sugar, flavonoids, total polyphenols and the degrandation of VC. Among all the treatments, the massfraction of 1.0% in CMC-Na had the best preservation effect, which could effectively prolong the fresh-keeping period of Chaenomeles sinensis.
