Summary
The aspartame is an artificial sweetener was discovered accidentally in the United States by J. M. Schlatter in 1965. In this work the kinetic of the thermal decomposition of sweetener, containing aspartame as sweetening agent, by means isothermal TG method was studied. The comparison of thermogravimetric data to the reference profiles of standard aspartame and lactose suggests an interaction between the two components in the sweetener, due to the decrease in the thermal stability of sweetener and of the overlapping processes. In the isothermal kinetic study the sweetener exhibited lower activation energy values, indicating a lower stability corroborating the thermoanalytical data. In case of the sweetener, the lower activation energy can be related to the interactions which took place between its components.
