Effects of Rice Bran Dietary Fiber Particle Size and Addition Dosage on the Pasting Properties of Rice Starch
摘要
Abstract
To investigate the effect of the particle size and addition dosage of rice bran dietary fiber on the pasting properties of rice starch,rapid viscosity analyzer system ( RVA) was employed to monitoring the pas-ting properties of the rice starch.The results demonstrated that different varieties of rice starch had different pasting characteristic values.When the dietary fiber content increased from 0%to 15%,the peak viscosity,set-back and breakdown values of the Japonica rice starch group decreased by 50.78%,30.36%and 73.11%,the peak time delayed for 1.66 min,the trough viscosity and final viscosity increased by 95.20%and 7.25%re-spectively.As for the Indica rice starch group,the peak viscosity,setback and breakdown values decreased by 18.37%,29.05%and 54.48%,the peak time delayed for 0.74 min,the trough viscosity and final viscosity in-creased by 23.96%and 7.61%respectively.The addition of the rice bran dietary fiber had no effect on the pas-ting properties of the Glutinous rice starch group( P>0.05) .The effects of pasting properties of rice bran dietary fiber particle size( Less than 80 meshes) on Japonica rice starch,Indica rice starch and Glutinous rice starch were not significant ( P>0.05) .The addition dosage(0%-15%) of rice bran dietary fiber in Japonica rice starch and Indica rice starch had a positive correlation with the peak viscosity( P<0.05) ,setback and breakdown val-ues,and had a negative correlation with trough viscosity,pasting temperature and peak time( P<0.05) .No sig-nificant correlation existed between the rice bran dietary fiber particle size and the pasting properties of the three kinds of rice starch in the work.关键词
