    Abstract
    This study was conducted to determinethe encapsulation characteristics of black cumin seed and sesame seed extract by using various types of coating materials as potential antioxidant source.This research used a complete randomized design (CRD) with two factors: the ratio of black cumin extract with sesame seed extract (E): 100%: 0%, 75%: 25%, 50%: 50%, 25%: 75% 0%: 100% and type of coating material (N): maltodextrin: soy protein, maltodextrin: gelatin, maltodextrin: casein.In this research, an analysis of chemical and phytochemical characteristics of encapsulation of black cumin seed and sesame seedextracthas been found as follows: water content,ash content, protein content, fat content,fiber content, reducing sugar content,IC50 value, qualitative analysisof flavonoidand phenolic.Comparison of black cumin extract 75% and sesame seed extract 25% with coating material maltodextrin : soy protein give the highest antioksidant activity of the combination of both materials used.
     
    Penelitian ini dilakukan untuk mengetahui karakteristik enkapsulasi ekstrak biji jintan hitam dan biji wijen dengan menggunakan berbagai jenis bahan penyalut sebagai sumber antioksidan potensial. Penelitian ini menggunakam rancangan acak lengkap (RAL) dengan dua faktor yaitu perbandingan ekstrak biji jintan hitam dengan ekstrak biji wijen (E) : 100% : 0%, 75% : 25%, 50% : 50%, 25% : 75%, 0% : 100% dan jenis bahan penyalut (N) : maltodekstrin : soy protein, maltodekstrin : gelatin, maltodekstrin : kasein. Pada penelitian ini telah dilakukan analisis terhadap karakteristik kimia dan fitokimia enkapsulat ekstrak biji jintan hitam dan biji wijendiantaranya kadar air, kadar abu, kadar protein, kadar lemak, kadar serat, kadar gula pereduksi, nilai IC50, pengujian flavonoid kualitatif, dan pengujian fenolik kualitatif. Perbandingan ekstrak biji jintan hitam 75% dan ekstrak biji wijen 25% dengan bahan penyalut maltodekstrin : soy protein memberikan aktivitas antioksidan tertinggi dari kombinasi kedua bahan yang digunakan.
