In the experiment,the peeled barley powder was used as the main raw material,and the extruding modification was carried out by the twin screw extruder.Four factors,including the extruderⅣtemperature(80,90,100,110,120℃),adding water(14%,17%,20%,23%,26%),screw speed(50,60,70,80,90 r/min),feeding speed(7,8,9,10,11 kg/h)were used to study the effects of each factor on the gelatinization characteristics of highland barley,including gelatinization characteristics,water absorption and descent value as the main reference indexes.The orthogonal test o...
