The infrared microwave puffing carrots chips technology research, analyzes the different microwave power and infrared power and heating time on carrots chips of sensory quality and the effect of using the experiment of three factors a[1]nd three levels.Get the best puffing carrot chips by establishing regression equation.At the same time, we analyzed the correlation between the two key evaluation indexes of sensory score and crispness.Results show that to obtain the best quality the parameters are microwave power 1019 w, infrared power 490 w, heating time 36 minutes.Under these circumstances puffing carrots chips of sensory evaluation score the highest, quality is the best.
