Abstract: The dried pepper,red pepper and green pepper were taken as main material,the technological application of fired chill in Sichuan was studied.The best formula material was set by L9( 33) orthogonal test.On the single- factor test based on the response surface method,the processing parameters were optimized.Results were as followed.Dried pepper,red pepper and green pepper with the quality of burnt chili were significant( p < 0.05).Red pepper had the biggest influence,and after it the green pepper.Dried pepper had the least impact.The effect order of parameters of technology on the impact was cooking frequency,oil temperature,solid- liquid ratio,processing time.Oil temperature had significant effect on the indexes( p < 0.05).Cooking frequency on the fired chill was significance( p < 0.01).The best processes was dried chillies 120 g,red peppers 20 g and green pepper 10 g,oil temperature of 158 ℃,processing time of 1.4 min,cooking frequency 16 r·min- 1,solid liquid ratio of 28∶ 100,which was required for the best quality of fired chill.
