Fractional crystallization of coconut oil in acetone
Abstract
Low-temperature solvent fractional crystallization was employed to enrich long-chain saturated fatty acids (LCSFA) and medium-chain fatty acids (MCFA) or unsaturated fatty acids (UFA) in coconut oil (CNO), and to optimize conditions for increased yield of high melting-point solid fractions (coco-stearin). Tests showed that acetone was the most suitable solvent. The optimum conditions for crystallization were 10 C for 6 h in an acetone-CNO ratio of 2:1. By single-step fractionation (SSF), coco-stearin was enriched by 4.6%, while by multiple-step fractionation (MSF), coco-stearin III was enriched by 4.4%. By SSF, UFA was enriched in olein by 13.6%, in olein II by 15.6%, and in CNO by 10.8%. The yield of coco-stearin in SSF was 28.3% and in MSF 21.7%.
