Abstract

Fish oil is a lipid fraction that can be obtained from the extraction process of fish meat and by-products of fish processing. Generally, fish oil is in the triglyceride form, but tends to be unstable and easily oxidized, therefore fish oil is converted to the ethyl ester form which has better stability against oxidation. This study aims to analyze the effect of the transesterification process conditions using the sonication method on the yield and quality of fish oil ethyl ester produced. The design used was a Completely Randomized Factorial Design with 2 factors, there were the sonication time (10, 20, and 30 minutes) and the concentration of KOH catalyst (0.5, 1.0, and 1.5%). The results showed that the highest yield value was found in the 10 minutes and 0.5% KOH of 91.38%. The best ethyl ester quality from the data obtained was found in the 30 minutes and 0.5% KOH with a FFA value of 0.50%, acid value of 1.09 mg KOH/g, saponification value of 214.93 mg KOH/g, ester value 213.84 mg KOH/g, peroxide value 5.86 meq/kg, p-anisidin value 30.02 meq/kg, total oxidation value 40.44 meq/kg, density 0.8745 g/m3, and viscosity 4.81 mm2/s. Keywords: fish oil, transesterification, sonication

Abstract

Sucrose ester is a renewable raw material that is environmentally friendly, non-toxic, biocompatible, and biodegradable with emulsification, stabilizing, and conditioning characteristics, so it is widely used in emulsion product applications. This study aims to characteristics the sucrose ester from methyl Myristic using K2CO3 and Na2CO3 as catalysts. The synthesis of sucrose ester uses methyl Myristic, which is a renewable raw material. Synthesis of methyl myristic was carried out by the esterification method, the synthesis of sucrose ester was carried out by the transesterification method with free solvent, the catalyst used was alkaline K2CO3 and Na2CO3 (6%), the reaction was carried out at 60°C for 30 minutes then 110°C for 90 minutes. The analyzes carried out were FTIR, HPLC, pH, foam stability, emulsion stability, surface tension, interfacial tension, contact angle, particle size, and polydispersity index. The results showed the characteristics of sucrose ester using K2CO3 were better than Na2CO3. The resulting characteristics are the sucrose ester group present at a wave number of 1726 nm, sucrose ester content 96,87%; the pH 10.73, foam stability 88,06%, the emulsion stability 63,68%, the surface tension 29.64 cm/dyne, interfacial tension 2,96 cm/dyne, contact angle 36,85°, particle sizes in the range of 2,35-9,74 µm, and a polydispersity index value 0.412. The resulting sucrose myristate can be applied to the cleaning, personal care, and cosmetic industries Keywords: catalysts, methyl myristic, sucrose ester
