Abstract:Fresh potatoes were used as raw materials，which were steamed，blended and fried to made potato nutritious meal.The uniform experimental design combined with fuzzy mathematical sensory evaluation was used to optimize the formula of mashed potato nutrition meal.The uniform test results were quadratic polynomial stepwise regression analysis，the results indicated that the equations coefficients of regression was 0.974 0，coefficient of association was 0.986 9，F value was 31.27，p value was 0.000 8，the standard deviation S was 1.86.The equations fit maximum value was 92.41，the optimum formula were mashed potatoes 1.77 kg，marinated beef 0.11 kg，petits pois 0.10 kg，potato starch 0.02 kg，colza oil 39.60 mL，salt 1.90 g.According the best formula to conduct validation tests，the results indicated that the fuzzy mathematics sensory score of the validation sample was 89.20，compared with the fitting value of regression equation，the error percentage was 3.47%.The fitting accuracy of regression equation was high，and the result of the best formula was accurate and reliable.
