Lastri Wiyani, Andi Aladin, Zakir Sabara, M Mustafiah, Rahmawati Rahmawati

Abstract

Emulsi Virgin Coconut Oil (VCO) merupakan produk yang dibuat dengan mencampurkan VCO dan air dengan menggunakan emulsifier.  Pembuatan emulsi VCO yang stabil dan dapat diterima konsumen akan menguntungkan industri yang memproduksi VCO.  Telah dilakukan penelitian tentang  pengaruh waktu dan kecepatan homogenisasi terhadap sifat fisik dan kimia emulsi VCO-sari jeruk dengan menggunakan emulsifier gum arab. Emulsi dibuat dengan mencampurkan VCO dan sari jeruk  (9:1) dan emulsifier gum arab 0,75 persen. Proses homogenisasi dilakukan selama 2, 4 dan 6 menit dengan kecepatan 5000, 10000 dan 15000 rpm. Emulsi yang dihasilkan ditentukan stabilitas dan viskositasnya. Waktu terbaik yang menghasilkan produk stabil adalah 4 menit dan kecepatan homogenisasi 15000 rpm. Emulsi VCO yang dihasilkan mempunyai viskositas 52,5 cP dan stabil pada suhu ruang.
