Analisis Identifikasi Komposisi Asam Lemak pada PSOFA (Palm Stearin Oil Fatty Acid) dengan Metode Kromatografi Gas di PT. Soci Mas Oleokimia

Abstract

Background: Palm Stearin Oil Fatty Acid (PSOFA) is a fatty acid rich in long-chain saturated fatty acids in the form of palmitic acid (C16). It is the result of the hydrolysis of Refined Bleached Deodorized Palm Stearin (RBDPS) using nickel as a catalyst. Objective: This study aims to analyze and identify the fatty acid composition of PSOFA (Palm Stearin Oil Fatty Acid) at PT. Soci Mas Oleokimia. Method: This study was conducted using a Shimadzu 2010 Plus Flame Ionization Detector (FID) gas chromatography and GLC 86 as the standard. Results: The results of this study were obtained in the form of a chromatogram that provides the percentage (%) of fatty acid content contained in the PSOFA sample: C12 (0.14%), C14 (1.15%), C16 (60.03%), C18 (5.27%), C18:1 (26.67%), C18:2 (5.86%), C20 (0.46%) and there are also four impurities contained with concentrations of 0.07%, 0.10%, 0.13%, 0.10%, respectively. Conclusion: The results of the fatty acid composition content in PSOFA that have been obtained are in accordance with the specification range set by PT. Soci Mas Oleochemical.
