Abstract: 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 guar gum. The stagnate effect of complex sol for K+ is more than for VC.

Key words: complex fiber, sol, matter transfer
