Congregation obtained after chitosan k and a treatments showed more tightness than sediments obtained without chitosan treatment, sediments after chitosan b and c treatments were network in structure. Mixed systems of pectin, protein and polyphenol were applied for studying a simulated system of kiwifruit juice. It was shown that the aggregates of pectin molecules in pectin solution were dispersing tubular globules. 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。

The strain X_6 was a non-flocculence strain with higher fermentation degree and the strain N_1 was a strain with lower fermentation and stronger flocculence.
