Medical - Biology (-tech,-chem,micro-) / vegetable oils | | German term or phrase: Umnetz-Verfahren | In an article entitled "Isolierung reiner Fettsäuren aus Fetten und Ölen, I encounter this word, e.g., Umnetz-Verfahren mit Detergentien.
I find no hits on the Internet, other than a Proz query explaining that in French this might be "separation par mouillage."
These articles deal with obtaining PUFAs from vegetable seed oils rather than fish oil.
Occurs in a table, where the three items are:
Flüssig/flüssig-Extraktion
Harnstoff-Addukt-Bildung
Umnetz-Verfahren mit Detergentien
There has got to be a direct translation (hopefully), since I cannot fit in a paraphrase here. |

would make sense, wouldn't it. since detergents are mentioned :)

essentially it's 'micelle formation' |

42 mins confidence:   peer agreement (net): +1 rolling-up process
Explanation:
Umnetzverfahren = rolling-up process (Römpp Chemie Lexikon - hardcopy)
Technical oleic acid is obtained from tallow. To obtain a sufficiently low cloud point, as measured by the method of Deutsche Gesellschaft fur Fettforschung D-III 3 [79], special measures have to be taken to purify the fatty acid mixture, i.e. most of the saturated fatty acids are removed by so-called rolling-up separation. The cloud point of the fatty acid mixture is thus reduced to values of 5° C. to 10° C. The mixture consisting, for example, of 67% oleic acid, 12% linoleic acid and 2% stearic acid is marketed under the name of Edenor® TiO5 and, on esterification with trimethylol propane, gives esters with a cloud point of -20° C. and a pour point of -40° C. ...
However, the rolling-up process remains confined to fatty acid mixtures which still have a relatively high linoleic acid content. Accordingly, the cloud point of a high-oleic fatty acid mixture from new sunflowers cannot be reduced to 5° C. by rolling-up separation because pure oleic acid already has a melting point of 14° C.

Die Trennung von gesättigten und ungesättigten Ci i8~ Fett " säuren wird als fraktionierte Kristallisation durchgeführt. Vorzugsweise handelt es sich hierbei um eine Umnetztrennung.
Unter dem Begriff Umnetztrennung ("Rolling-up Process") ver¬ steht man die Trennung von gesättigten und ungesättigten Fettsäuren mit in der Regel 12 bis 18 und vorzugsweise 16 bis 18 Kohlenstoffatomen, die auf destillativem Wege infolge der sehr ähnlichen Siedepunkte nicht oder nur mit hohem techni¬ schen Aufwand durchgeführt werden kann. Eine Übersicht zu diesem Thema ist von K.Schmid in Fat Sci.Technol. j39_, 237 (1987) veröffentlicht worden.
