The effect of addition of dextran on the apparent viscosity of molasses was
studied, using a Brookfield Rheometer. The apparent viscosity was found to
increase with the addition of dextran and decrease with increase in rpm. T
he behaviour observed with and without dextran was pseudoplastic. The appar
ent viscosity of molasses was found to depend on temperature. The dependenc
e of apparent viscosity on temperature was related through the Arrhenius la
w. The activation energy observed was in the range of 2.237-2.482 kcal/g. m
