The encapsulation process used maltodextrin as wall material. Maltodextrin was mixed with concentrated red
dragon fruit anthocyanins at ratio 1:10 (v/v) and stirred until homogenized using homogenizer for 20 min. The
mixture was put in a petri dish for drying process in a domestic microwave oven. For drying process, 1
variable was used that is time of drying, with fixed heating power. In this study only 30%P was used from
1100W of power. For the time of heating, 5 different drying time were used: 1 min, 1.5 min, 2 min, 2.5 min and
3 min.
