摘　　要：以质量分数为2:3的大豆非水溶性纤维素(soybeaninsolublefiber,SIF)和瓜尔豆胶(guar)配制固形物含量为5g/200ml的复合纤维素溶胶,采用SEM(scanningelectronmicroscopy)进行了显微观察、分析,模拟人体中营养物质的吸收条件,进行了体外营养物质传递实验,测定了复合纤维素溶胶中葡萄糖、VC、K+的传递特性后发现,在试验浓度下的复合溶胶体系中,葡萄糖的传质速率仅为在单组分的SIF悬液及guar溶胶中的50%以下;复合溶胶对VC的滞留能力较弱,而对K+的滞留能力较强。The complex sol containing solid phase matter 5g/200ml is compounded with mixture combined with soybean insoluble fiber（SIF） and guar gum in 2：3. The structure of the complex sol is observed and analyzed with scanning electron microscopy（SEM）. The matter transfer test is simulated at assimilating nutriment model in body. The transmissibility of glucose, VC, K＋ in sol is measured. On the test condition, the transmissibility of glucose in the complex sol is no more than 50% of that in the sol of SIF or gnat gum. The stagnate effect of complex sol for K＋ is more than for VC.
