Thermal Decomposition Mechanism Study of 6-Gingerol/Maltosyl-β-Cyclodextrin Inclusion Complex

The thermal stability and decomposition mechanism of 6-gingerol/maltosyl-β-cyclodextrin inclusion complex were studied with TG-DSC and kinetic analysis method. Kinetics parameters and thermal mechanism of the inclusion complex were deduced by Kissinger and Ozawa-Flynn-Wall calculation method. The results showed that the thermal decomposition temperature of the inclusion complex was in the range of 300.00~500.00℃,the apparent activation energy was 49.54 kJ/mol,the pre-exponential factor was 27.54 min^-1,and the decomposition mechanism function was G(α)=-ln(1-α)^3/2,the decomposition mechanism was consistent with random nucleation and subsequent growth mechanisms.
