The viscosity properties of break flour, middling flour, and oat flour (mixture of break flour and middling flour with nature milling ratio) were investigated. The results showed that after high-temperature treatment, the average gelatinization temperature of break flour, middling flour and oat flour decreased significantly, which were lower than that of oat without high-temperature treatment. Their peak viscosity, final viscosity and hold viscosity increased both under air-heating (140℃, 155℃) and far-infrared heating (200℃), compared with non-treated samples. With the temperature of high-temperature effects treatment increasing gradually, their viscosity properties decreased.
