Effect of Feed Flowrates on the Physical Properties and Antioxidant of Mahkota Dewa (Phaleria Macrocarpa) Encapsulated Powder

This paper presents an experimental study on the encapsulation of Mahkota Dewa extracts by maltodextrin using spray drying. The bioactive compound from dried was obtained a subcritical water extraction process prior to drying process. effect feed flow rate (485 2115 ml/h) investigated one-factor-at-a-time (OFAT). It observed that mean particle size increase varied 3.55 8.38 µm when increased 485 ml/h. Moisture content 4.88 6.83% as ml/h, whereas antioxidant activity slightly 90.48 91.65%. findings this showed decrease in reduces activity, moisture content, and size. ABSTRAK: Kertas kerja ini adalah berkenaan kajian eksperimen melalui proses pengkapsulan ekstrak buah dengan menggunakan maltodekstrin teknik pengeringan semburan. Sebatian bioaktif dari kering diperoleh pengekstrakan air subkritikal sebelum Kesan kadar aliran masuk hingga ml/jam) dikaji konsep satu-faktor-pada-satu-masa Dapatan mendapati bahawa purata saiz zarah meningkat kepada ketika sehingga ml/jam. Kandungan kelembapan kenaikan ml/jam, sedangkan aktiviti antioksida sedikit menunjukkan penurunan berkurang antioksida, kandungan dan zarah.
