Extraction of fatty acid from mango seed kernel using supercritical carbon dioxide by response surface methodology

Abstract

The extraction of mango seed kernel oil by using innovative extraction and conventional techniques is described. For conventional techniques, maceration and soxhlet were applied by using 95 % ethanol and hexane as solvent. For innovative extraction, the supercritical carbon dioxide (ScCO2) as solvent was applied by using response surface methodology. The efficiency yield of extracted oil from soxhlet with 95 % ethanol was the unique technique with 37.1 % yield and the ScCO2extraction was the lowest technique with 3.13 % yield at 2 h of extraction time. The fatty acid compositions of mango seed oil from different techniques were similar, but the fatty acid composition of mango seed kernel oil from ScCO2extraction had greatest total saturated fatty acid with 54.6 % and more highly selective with special of arachidic acid with 11.6 %. It is considered that the ScCO2extraction is competitive with conventional extraction.
