Conclusion
The results presented here clearly demonstrate that
cooking methods influenced the antioxidant capacityand volatile compounds during processing of kaffir
lime leaf. Favorable effect on phenolic compounds
and antioxidant activities was achieved by steaming
and whereas other cooking method studied provided
adverse results except for boiling which increased
antioxidant capacities but not TPC and TFC.
Changes in the concentrations composition of the
volatile compounds as affected by different means of
cooking were also observed. We have demonstrated
the importance of how cooking methods influence
antioxidant properties and bioactive components of
plants. This would be valuable for process design or
cooking plans to preserve the bioactive compounds
and their health benefits of kaffir lime leaf.
