چکیده
|
Dextrinization of corn starch by twin screw extruder was studied. the effect of extruder operating conditions (five different screw speeds: 35, 45, 55, 65, and 70; and three temperatures: 125, 130, and 135 _c) on some physicochemical properties of dextrin (total soluble solid, water absorption index, water solubility index, and total color difference) was investigated. results showed that as the screw speed and temperature of extrusion were increased the water absorption index of dextrin tended to drop meanwhile the total soluble solid, water solubility index, and color were inclined to rise. the range of total soluble solid, water absorption index, water solubility index and total color difference was 2.1–4.6 brix, 159–203%, 20–51%, 3.5–14.1, respectively.
