Abstract：Optimization of gluten high moisture extrusion organizational process, to broaden the application field of wheat gluten, gluten product development has great significance. The experiment with wheat gluten and starch as the main raw material, using a double-screw extruder, respectively investigates the temperature to 125℃、130℃、130℃、140℃、145℃, the speed of 23r/min、30r/min、36r/min、45r/min、52r/min, and the moisture content of 40%、41%、42%、43% and 44% when the influence of the important indicators of product. Based on temperature, speed, water single factor experiment, through orthogonal table L9 (34) finally the optimized process parameters is determined. Gluten results show that the optimal organizational process parameters to 45 r/min, the screw rotation speed of material moisture content is 43%, the barrel temperature 145℃. Under the best conditions after extrusion, the hardness of sample is 4.59N, the elasticity of 1.53mm, chewiness was 5.50MJ, organized degree of 6.14.
