Tujuan penelitian ini adalah menentukan rasio berat optimum K 2 CO 3 terhadap metil ester asam lemak dalam sintesis ester asam lemak sukrosa ( FACE ) dan menentukan stabilitas FACE sebagai emulsifier. Sintesis FACE dapat dilakukan melalui pembentukan metil ester asam lemak ( FAME ) terlebih dahulu. Selanjutnya, FAME direaksikan dengan sukrosa menggunakan katalis basa K 2 CO 3 dan menghasilkan FACE. Sintesis FACE dilakukan dengan variasi rasio berat katalis K 2 CO 3 terhadap FAME 1,5%, 3%, 4,5%, 6%, dan 7,5%. Hasil penelitian menunjukkan bahwa banyaknya katalis dapat mempengaruhi FACE yang dihasilkan. Kondisi optimum FACE terjadi pada hasil sintesis dengan rasio berat K 2 CO 3 terhadap FAME 6%, mempunyai derajat transesterifikasi tertinggi sebesar 0,7984 dan memiliki stabilitas emulsi yang paling stabil sebesar 304,14 detik.}, issn = {2597-9914}, pages = {17--20} doi = {10.14710/jksa.14.1.17-20}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/17415} }
