Study on optimization of starch mixtures of different parameters and the change of application properties

The mung bean starch,potato starch,cassava starch and corn starch were used as raw materials,according to a certain percentage of compound to increase the viscosity of corn starch,then used the peak of viscosity to establish multiple linear regression equation,with the equation,deduced the mixtures of several starch ratio to improve the peak viscosity of corn starch,at last according the two factors of RVA viscometer rapid validation and production costs to determine the optimal compound parameters of starch. In this study,the starch peak viscosity get from the proportion of the selected compound were higher than corn starch,the transparency of the paste were higher than corn starch,freeze-thaw stability,enhanced level of anti-aging properties,difficult to condensation and precipitation,but thermal stability of starch paste decreased.
