Abstract
The objecti ve of this work was the evaluation of neohesperidin dihydrochalcone thermostability. For this acceler ated stability stud y, we ha ve used an isothermal method at three temper atures (50, 70 and 90 °C). The thermodegradation of aqueous diluted solutions of neohesperidin dihydrochalcone at various pH was studied . This degradation appeared to follow first-order kinetics and was found to be pH-dependent. In the best stability conditions (pH = 4.50), the experiments revealed an acti vation energy ( Ea) of 45.8 kJ mol -1 and a t90% of 164 days, at 20 °C.
