Abstract
The present invention relates to an enriched LCMUFA composition comprising cetoleic acid. Furthermore, the invention relates to a method for providing an enriched composition comprising cetoleic acid, and to the use of such compositions.
Claims24
A composition enriched in long chain monounsaturated fatty acids (LCMUFAs), the composition comprising C22:1 n11 (cetoleic acid) and C20:5 n3 (EPA),
- wherein the fatty acids of the composition are derived from a natural oil comprising cetoleic acid and EPA, and wherein
- the concentration of cetoleic acid is at least 16.0 wt. %;
- the EPA concentration is at least 3 wt. %;
- any concentration of DHA is maximum 4 wt. %, and
- wherein the EPA:DHA ratio is at least 4:1, and
- the composition comprising the fatty acids in form of ethyl esters, free fatty acids or fatty acid salts.
A method for preparing a composition enriched in long chain monounsaturated fatty acids (LCMUFA) comprising at least 16 wt. % cetoleic acid (C22:1 n11), from a natural oil comprising LCMUFAs including cetoleic acid, and long chain polyunsaturated fatty acids (LCPUFAs),
- the method comprising the steps of:
- i) selective transesterification of fatty acids of the natural oil by mixing the natural oil with a lipase and ethanol, to obtain a mixture comprising LCPUFAs on glyceride form and LCMUFAs on ethyl ester form;
- ii) distilling the mixture of step i) to separate LCMUFAs as one fraction and LCPUFAs as another fraction, collecting the LCMUFA fraction to obtain the LCMUFA enriched composition.
