Abstract

Rosela (Hibiscus sabdariffa L) memiliki antosianin dan vitamin C dalam jumlah yang cukup tinggi.  Kandungan antosianin dan vitamin C ini mempunyai peran yang penting untuk menangkap radikal bebas yang mampu menyebabkan penyakit degenerative. Pengolahan rosela banyak dilakukan dalam bentuk kering untuk mempermudah penanganan rosella dan meningkatkan daya awet rosella namun perlu diteliti metode pengeringan yang bagaimana yang mampu mempertahankan komponen bioaktif yang terkandung di dalamnya.  Dalam penelitian ini dilakukan dua metode pengeringan yaitu dengan cabinet dryer (60oC, 6 jam) dan dengan fluidized bed dryer (70oC, 1.5 jam). Hasil penelitian menunjukkan bahwa kandungan antosianin, vitamin C dan kapasitas antioksidan rosella kering dengan menggunakan pengeringan cabinet dryer lebih tinggi disbanding menggunakan fluidized bed dryer
