Abstract

Foreliggende oppfinnelse gjelder en fremgangsmåte for å separere triglyserid-holdige spiselige oljer i fraksjoner som er anriket i flerumettede triglyserider og fraksjoner som er anriket i mettede triglyserider. Oppfinnelsen er særlig egnet for separering av triglyserid-holdige oljer utledet fra fisk. Fremgangsmåten omfatter (a) størkning av den spiselige olje ved utnyttelse av lav temperatur og (b) ekstrahering av den størknede spiselige olje med et polart organisk løsningsmiddel ved en temperatur på -50°C eller lavere, hvor ekstraktet omfatter den flerumettede anrikede olje og restmengden omfatter den mettede triglyserid-anrikede størknede olje. Størkningstrinnet utføres fortrinnsvis ved å blande olje med flytende nitrogen og ekstraheringstrinnet utføres fortrinnsvis med aceton.The present invention relates to a process for separating triglyceride-containing edible oils into fractions enriched in polyunsaturated triglycerides and fractions enriched in saturated triglycerides. The invention is particularly suitable for separating triglyceride-containing oils derived from fish. The process comprises (a) solidifying the edible oil using low temperature and (b) extracting the solidified edible oil with a polar organic solvent at a temperature of -50 ° C or lower, the extract comprising the polyunsaturated enriched oil and the residual amount. comprises the saturated triglyceride-enriched solidified oil. The solidification step is preferably carried out by mixing oil with liquid nitrogen and the extraction step is preferably carried out with acetone.
