摘要

该文以新鲜桑叶菜为原料,采用自发气调包装技术贮藏,研究了采后处理时间间隔(1、2、4 h)对桑叶菜品质的影响。结果发现,随着采后处理时间间隔的延长,桑叶菜的可溶性糖、可溶性蛋白、VC和多酚等含量降低,木质素含量和硬度等逐渐增加,细胞膜透性增大和丙二醛积累加剧。这些结果表明,采后处理时间间隔的延长会加速桑叶菜采后品质劣变,不利于后续贮藏过程中品质的维持,桑叶菜采后商品化处理前的品质变化规律的明确,有望为桑叶菜采后商品化处理及贮运保鲜提供理论基础。

Abstract

To investigate the quality deterioration pattern of mulberry leaf vegetables during the period between postharvest and commercial handling, quality attributes before and after passive modified atmosphere packaging were studied. The results showed that the contents of soluble sugar, soluble protein, VC and polyphenol decreased with the prolongation of postharvest treatment interval (1, 2 and 4 h), while the lignin content, hardness, membrane permeability and MDA contents increased gradually. Overall, the quality deterioration of mulberry leaf vegetables was enhanced with the increase of postharvest treatment interval, which was adverse to the quality and nutrition maintenance during subsequent storage. Identifying the quality deterioration pattern of mulberry leaf vegetables is expected to provide theoretical foundation for mulberry leaf vegetables postharvest commercial handling and storage.
