Particles in mixed solution of pectin and bovine serum albumin had two states: one was circular in photo, the other contained single particle or aggregates of several particles. Pectin decreased the interaction between protein and polyphenol and strengthened the stability of mixed solution of pectin, protein and polyphenol. Chitosan flocculated mixed solution of pectin, protein and polyphenol, and the floccule was white, having a network structure.

用果胶-蛋白质-丹宁酸混合体系作为猕猴桃原果汁的模拟体系研究结果表明：1、果胶溶液中果胶分子聚集物呈中空球形均匀分散；2、果胶／牛血清白蛋白混合溶液中的球形粒子有两种：粒子中央光线可透过，照片上呈环形；粒子的中央包含有单个或多个球形粒子的聚集体，认为粒子的中央是蛋白质，外层是果胶；3、果胶的存在抑制或减弱了蛋白质-丹宁酸之间的相互作用，果胶起到防止蛋白质-多酚产生沉淀的作用，增强了溶液的稳定性；4、壳聚糖加入果胶-蛋白质-丹宁酸混合溶液中时，可以絮凝果胶-蛋白质-丹宁酸混合溶液，溶液中出现白色的网状絮凝物。

On the base of the constructing phylogenetic tree using PAUP 4.0, MP and NJ (neighbor-joining) trees of diverse pectate and pectin lyases showed that pectate lyases from plant, pectin lyases from fungi and pectate lyases from bateria belong to different groups, respectively. The pectate lyase A of Aspergillus nidulans is more closely related to plant pectate lyases than to pectin lyase from fungi and pectate lyases from bacteria. The pectin lyase from Pseudomonas syringae is more closely related to fungi pectin lyases than other lyases.

构建的MP树和NJ树(neighbor-joining)显示：来自植物的果胶酸裂解酶、真菌的果胶酸酯裂解酶、细菌的果胶酸裂解酶分别可聚为一个独立的类群；相对于细菌果胶酸裂解酶和真菌果胶酸酯裂解酶而言，构巢曲霉的果胶酸裂解酶A和植物的果胶酸裂解酶之间有较近的亲缘关系；细菌Pseudomonas syringae的果胶酸酯裂解酶和真菌的果胶酸酯裂解酶之间的亲缘关系较近。
