    Abstract:

    This paper investigated the pasting and rheolgical properties of corn starch/guar gum and waxy corn starch/guar gum mixed systems.Moreover,the microstructures of starch/guar gum mixed systems were also observed by SEM.The results showed that the mixture pastes added with guar gum exhibited a more significant thickening effect and superior viscoelastic properties.The synergistic interaction was much more pronounced in corn starch/guar gum mixed systems.A decrease in the pasting temperature and behavior index of corn starch/guar gum mixed systems has been attributed to interactions between the guar gum molecules and amylose molecules.The SEM images showed the starch/guar gum mixed systems presented a more uniform and tight network.
