Improved extraction of green tea components from teabags using the microwave oven

► The optimal extraction of green tea components from teabags was determined. ► Boiled water extraction with the teabag manufacturers' instructions was suboptimal. ► Using the microwave oven with room temperature water was not effective. ► Boiled water for 0.5 min followed by microwaving (MAE) was more effective. ► MAE for 1 min after boiled water brewing for 0.5 min was the best household method.
