Process for the preparation of a concentrate of esters of polyunsaturated fatty acids. |
摘要 |
<p>Prepn. of a concentrate of polyunsatd. fatty acid ethyl esters comprises: a) ethanolysis of an oil rich in polyunsatd. fatty acids, which has been previously refined, using ethanol in the presence of a catalyst; b) complexion of these esters with urea in soln. in ethanol, giving an insol. inclusion complex; and c) sepn. of the inclusion complex and recovery of a fraction of ethyl esters rich in the polyunsatd. fatty acid esters in the liq. phase. The oil is pref. a vegetable oil rich in gamma -linolenic acid (evening primrose oil, borage oil or oil from the pips of the fruits of the Ribes genus, pref. blackcurrant), or a vegetable oil rich in linoleic acid and poor in alpha linolenic acid (partic. passion flower oil or maize oil) or a marine animal oil rich in eicosapentaenoic and docosahexaenoic acids. The concentrate in soln. in hexane is treated with activated carbon (10-40 wt.%) at room temp., the carbon sepd. and the hexane evapd.</p> |
