Ozone was a environment oxidant.5mg/L ozone was used to treat glutinous rice for different time(15,30,45,60min).The pasting properties and amylase activity of glutinous rice powder were detected.The results showed that:the pasting viscosity of glutinous rice powder was increased with ozone treatment time increasing,while the peak viscosity,the lowest viscosity and final viscosity were significantly higher than that of the control group(P0.05);the aging resistance was slightly weakened;falling number were increasing at the same change trend...
