The aim of this study was to improve the quality of pepper product by optimize process of emulsification and microencapsulation. The experimental design used in this study was Response Surface Methodology (RSM). The results showed that the selected emulsifier was arabic gum that had the highest solubility in water (99.78%). The optimum point of emulsification occured at 15% of concentration arabic gum and 4 minutes of homogenization time with the result was solubility in water 99.80%, and

The optimum point of microencapsulation process occured at 3:1 of maltodextrin and sodium caseinate ratio, 10% of coating material concentration, and 180°C of drying temperature with the result was essential oil content 1.04%, solubility in water 98.18%, surface oil 0.20%, water content 2.45%, oil recovery 77.07%, and the yield of microcapsule 69.87%Keywords: Pepper oleoresin, RSM, emulsification, microencapsulationABSTRAKPenelitian ini bertujuan untuk memperbaiki kualitas mutu produk oleoresin lada melalui optimasi proses emulsifikasi dan mikroenkapsulasi. Rancangan percobaan yang digunakan adalah Response Surface Methodology (RSM). Hasil penelitian menunjukkan bahan pengemulsi yang terpilih adalah gum arab yang memiliki kelarutan tertinggi dalam air (99,78%). Titik optimum proses emulsifikasi terjadi pada konsentrasi gum arab 15% dan lama homogenisasi 4 menit yang memberikan nilai kelarutan dalam air 99,80% dan stabilitas emulsi 97,15%. Titik optimum proses mikroenkapsulasi terjadi pada rasio maltodekstrin dan natrium kaseinat (3:1), konsentrasi bahan penyalut 10%, dan suhu inlet pengeringan 180°C yang memberikan nilai kadar minyak atsiri 1,04%, kelarutan dalam air 98,18%, kadar surface oil 0,20%, kadar air 2,45%, oil recovery 77,07%, dan rendemen 69,87%Kata kunci: Oleoresin lada, RSM, emulsifikasi, mikroenkapsulasi
