Ekstraksi Minyak Biji Pepaya dengan Pelarut n-Heksana

Abstract

Seeds from papaya have an oil content of around 32.6%, so it is very interesting to develop methods of taking oil from papaya seeds. Papaya seed oil is a vegetable oil that is used for cooking oil or cosmetic oils with low cholesterol levels. This study aims to determine the effect of solvent volume and extraction time in extracting oil from papaya seeds by extraction method using n-hexane solvent. After extraction is complete, the extraction results are then filtered and then distilled to vaporize the solvent so that the oil is left behind in the distillation flask. From the results of research conducted with a papaya seed weight of 30 g, extraction temperature of 55oC, and a stirring speed of 400 rpm, it was found that the more the volume of the solvent used, the greater the percentage of oil extracted. The optimal amount of solvent volume is 150 mL n-hexane with the percentage of oil taken up 22.67%. For the extraction time variable, the longer the extraction time, the greater the percentage of oil extracted. In this variable the optimal conditions are obtained at the time of extraction 90 minutes with the percentage of oil taken by 26%.
