The glutinous rice powders were used to study the impacts of different trehalose content on the characteristics of glutinous rice powders. The results showed that with the increase of trehalose content, the pasting temperature was not significantly impacted. The peak viscosity, valley viscosity and final viscosity increased at first then decreased and when the content was up to the maximum 1.0%. The thermal stabilities strengthened integrally and with the increased of the content, the thermal stabilities strengthened at first then attenuated. When the content was 1.5%, the thermal stabilities were the strongest. The gelling capabilities attenuated with the increased of the content. The transparency decreased at first then increased and steadied at last. The transparency was lowest when the content was 1.0% and highest when the content was 1.5%. The transparencies of powders at 25 ℃ were higher than that at 0 ℃. The freeze-thaw stability increased gradually with the increase of the content. The retro-gradations weakened gradually while the high temperature water-binding capacity increased gradually with the increase of the content then steadied.
