Abstract
This paper presents an experimental study on the encapsulation of Mahkota Dewa extracts by maltodextrin using spray drying. The bioactive compound from dried Mahkota Dewa was obtained using a subcritical water extraction process prior to a spray drying process. The effect of feed flow rate (485 to 2115 ml/h) was investigated using one-factor-at-a-time (OFAT). It was observed that the mean particle size increase varied from 3.55 to 8.38 µm when the feed flow rate increased from 485 to 2115 ml/h. Moisture content increased 4.88 to 6.83% as the feed flow rate increased from 485 to 2115 ml/h, whereas the antioxidant activity increased slightly from 90.48 to 91.65%. The findings from this study showed that decrease in feed flow rate reduces antioxidant activity, moisture content, and particle size.
