Mechanical relaxation processes due to sugars in cane (Arundo donax L.)

Abstract

The storage modulus and the mechanical loss tangent of untreated, extracted, and sugar- impregnated canes (Arundo donax L.) were measured over a temperature range of −150° to 0°C at low frequencies. Two relaxation processes, labeled α and β, were detected in the ranges −60° to 0°C and −120° to −100°C, respectively. The α and β processes shifted to lower temperatures with increasing moisture content. The α process was detected only in the canes containing sugar. The magnitude of its loss peak increased with an increase in sugar content. It was speculated that the α process was due to some interactive molecular motions of the adsorbed water and sugar. The β process, detected in all of the canes, was attributed to the motion of the adsorbed water in the amorphous cell wall substances.
