The apparent activation energy was found to decrease as the fructose content increased. The value of parameter x increased with the fructose content, while parameter beta decreased as the fructose content increased to 50%. The parameter x was also evaluated using the peak-shift method and was found to be slightly higher than those obtained from curve fitting to the TNM and the Adam-Gibbs models in all sugars. The fragility of the sugars was also evaluated using the enthalpy relaxation data. The addition of fructose to the glucose-fructose system produced ""stronger"" liquids, but less non-linear behavior. The change in the parameters x and beta with the thermal history (i.e., aging time, aging temperature and cooling-heating rates indicated the failure of the original assumption of the models for the sugar systems."
