Abstract

Daun tanaman kari (Murraya koenigii L.) diketahui mengandung senyawa aktif seperti flavonoid, saponin, fenol, alkaloid, tanin, dan glikosida. Tujuan dari penelitian ini adalah mempertahankan senyawa fenolik ekstrak daun kari dengan metode mikroenkapsulasi. Penelitian ini terbagi menjadi dua tahap yaitu penelitian pendahuluan dan penelitian utama. Pada penelitian pendahuluan, dilakukan ekstraksi daun kari dengan etanol. Pada penelitian utama, ekstrak etanol daun kari dimikroenkapsulasi dengan bahan penyalut berupa maltodekstrin dan whey protein isolate menggunakan metode spray drying. Pengaruh rasio core to coating (1:10 dan 1:20) dan suhu inlet spray dryer (125, 150, dan 175oC) terhadap mikrokapsul diamati dengan melakukan analisis berupa efisiensi enkapsulasi, kandungan fenolik total, aktivitas antioksidan, powder recovery, ukuran partikel, dan LC-MS. Berdasarkan hasil analisis, didapati adanya interaksi antara rasio core to coating dan suhu inlet spray dryer terhadap kadar air, efisiensi enkapsulasi, perubahan kandungan fenolik total, aktivitas antioksidan (IC50), dan perubahan IC50. Mikrokapsul terbaik berupa mikrokapsul dengan perlakuan rasio core to coating 1:20 dan suhu inlet 125oC dengan efisiensi enkapsulasi sebesar 98,222%, perubahan kandungan fenolik total sebesar 1,778%, perubahan aktivitas antioksidan sebesar 46,018%, dan ukuran partikel sebesar 1,59 μm. Hasil LC-MS menunjukkan bahwa mikrokapsul mampu mempertahankan senyawa fenolik yang terdapat pada ekstrak. / Curry leaves (Murraya koenigii L.) contain bioactive compounds such as flavonoid, saponin, phenol, alkaloid, tannin, and glicoside. The purpose of this research was to retain phenolic compounds of curry leaves extract with microencapsulation. This research is divided into two stages, which are preliminary and main research. In preliminary research, extraction of curry leaves was done with ethanol. In main research, the ethanolic extract of curry leaves as core material was microencapsulated with maltodextrin and whey protein isolate as coating materials using spray drying method. Effect of core to coating ratio (1:10 and 1:20) and inlet temperature of spray dryer (125, 150, dan 175oC) toward microcapsule was subjected to encapsulation efficiency, total phenolic content, antioxidant activity, powder recovery, particle size, and LC-MS. Based on statistical analysis, there were interactions between core to coating ratio and inlet temperature of spray dryer toward moisture content, encapsulation efficiency, change of total fenolic content, antioxidant activity (IC50), and change of IC50. Microencapsulation was best achieved with the combination of 1:20 core to coating ratio and 125oC inlet temperature with 98.222% encapsulation efficiency, 1.778% change of total phenolic content, 46.018% change of antioxidant activity, and 1.59 μm particle size. The result of LC-MS showed that microcapsule was able to retained phenolic compounds from extract
