In order to improve the quality of restructured potato rice, monostearin, sodium alginates and guar gums were chosen as quality improvers. The comprehensive score was used as index to optimize quality improver formula by single factor experiment and orthogonal experiment. The results indicated that the degree of effects on quality of restructured potato rice were guar gum > monostearin > sodium alginate. The optimum formula was monostearin 0.3%, sodium alginate 0.4%, guar gum 0.4%. Under such conditions, the comprehensive score increased from 72.80 to 85.97.It showed that the formula has obvious effect on the quality of restructured potato rice.
