【摘要】 果胶是高等植物细胞壁的重要组成成分,对于维持细胞结构起着重要作用。果胶与果实成熟软化过程中质地变化密切相关。本文综述了果胶的一般化学结构、结构模型、采后果实果胶的含量与组分变化、中性糖组成与多聚物纳米结构的变化,总结了采后不同质地变化类型果实的果胶降解模式,为深入认识果胶代谢在不同质地变化类型果实中的作用提供参考。更多还原

【Abstract】 Pectin is one of the most important components in cell wall materials of higher plants with the ability to maintain the integrity of cell wall architecture, which is closely related to the texture change of fruits. This review describes the structure and models of pectin, and the changes of pectin’s contents, components, neutral sugars and polymers’ nanostructure in some common fruits. Furthermore, this review analyses the degradation patterns of pectin in different fruits during softening, hoping to make reference for further understanding the role of pectin metabolism in different softening patterns of fruits.更多还原
