Abstract：
Rhamnogalacturonan type I (RG-I) is one of the pectin family member abundant in plant cell walls. Process of RG-I extraction from cell walls, either as a one-step or several-stage process, conditions the structure and properties of obtained polysaccharides. In this paper, we provide comprehensive overview of the factors related to the source and extraction techniques that determine the yield and chemical composition of pectin belonging to RG-I. The role of the source material, solvent, pH, temperature, time and additional factors related to applied techniques, such as microwaves, ultrasounds, high and low pressure or enzymatic treatments are discussed.
摘要：
鼠李糖半乳糖醛酸I型（RG-I）是植物细胞壁中丰富的果胶家族成员之一。从细胞壁中提取RG-I的过程，作为一个一步或几个阶段的过程，条件得到的多糖的结构和性质。在本文中,我们全面概述了与来源和提取技术相关的因素，这些因素决定了属于RG-I的果胶的产量和化学成分。源材料的作用，溶剂,pH值,温度,与应用技术相关的时间和其他因素，比如微波，超声波,讨论了高压和低压或酶处理。
