Description

  

   <Desc/Clms Page number 1> 
 



  Der   Extraktionarückstand   ist nach dem Abdestillieren des letzten Restes Alkohol ein vollkommen neutrales, farbloses Fett. Der zur Extraktion verwendete Alkohol wird ebenfalls abdestilliert und hinterlässt   die Gesamtfettsäure   und die im rohen Fett enthaltenen Farbstoffe. 



   II. Einem fast neutralen, jedoch gelben, fein zerkleinerten Illipetalg werden z. B. 5% seines Gewichtes farblose Illipetalgfettsäure, gleichfalls fein zerkleinert, zugemischt. Dieses Gemisch wird, wie im früheren Beispiel angegeben, mit Alkohol extrahiert. In den Extrakt geht nun ausser der geringen Mengen ursprünglich im Fett enthaltenen Fettsäure die zugesetzte Fettsäure und der gesamte Farbstoff, so dass, dem Zwecke dieser Operation entsprechend, ein neutrales, farbloses Fett resultiert. 



   III. Die den Borneotalg liefernden Samen von Shorea-Aptera werden wie gewöhnlich für Extraktionazwecke zerkleinert und bei zirka 150 C einer Extraktion mit Alkohol unterworfen. 



  Auf diese Weise wird den Samen die freie Fettsäure und ein Teil des Farbstoffes entzogen. Nach dem Vertreiben des Alkohols aus dem Extraktionsrückstand wird diesem das neutrale Fett auf gebräuchliche Weise durch Extraktion oder durch Pressen entzogen. Für den Fall, als man das im kalten Alkohol unlösliche, in warmem lösliche, neutrale Fett mit heissem Alkohol extrahieren wollte, ist es natürlich nicht nötig, den aus der ersten Operation stammenden Alkohol vorher völlig zu vertreiben. 



     PATENT ANSPRÜCHE   :   l.   Verfahren zur Entfernung der freien Fettsäuren und der nicht fettartigen Verunreinigungen aus Fetten und Ölen durch Extraktion mit Lösungsmitteln, in denen die Fette nur schwierig die Verunreinigungen und die Fettsäuren dagegen leichter löslich sind, dadurch gekennzeichnet, dass man die Fette bei Temperaturen unterhalb ihres Schmelzpunktes bzw. die Öle bei
Temperaturen unterhalb oder in der Nähe ihres   Erstarrungspunktes, zweckmässig nach   vor- 
 EMI1.1 
 extrahiert.

  After the last residue of alcohol has been distilled off, the extraction residue is a completely neutral, colorless fat. The alcohol used for extraction is also distilled off, leaving behind the total fatty acid and the colorants contained in the raw fat.



   II. An almost neutral, but yellow, finely ground Illipetalg are z. B. 5% of its weight of colorless Illipetalgfettsäure, also finely crushed, mixed in. As indicated in the previous example, this mixture is extracted with alcohol. In addition to the small amounts of fatty acid originally contained in the fat, the added fatty acid and all of the coloring matter go into the extract, so that, in accordance with the purpose of this operation, a neutral, colorless fat results.



   III. The seeds of Shorea-Aptera, which provide Borneo algae, are crushed as usual for extraction purposes and subjected to an extraction with alcohol at around 150 ° C.



  In this way, the free fatty acids and some of the color are removed from the seeds. After the alcohol has been driven off from the extraction residue, the neutral fat is removed from it in the usual way by extraction or pressing. In the event that one wanted to extract the neutral fat, which is insoluble in cold alcohol and soluble in warm alcohol, with hot alcohol, it is of course not necessary to completely drive off the alcohol from the first operation beforehand.



     PATENT CLAIMS: l. Process for removing the free fatty acids and the non-fatty impurities from fats and oils by extraction with solvents in which the fats are difficult to dissolve the impurities and the fatty acids, on the other hand, are more easily soluble, characterized in that the fats are removed at temperatures below their melting point or the oils at
Temperatures below or near their solidification point, expediently after
 EMI1.1
 extracted.

2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass das zu reinigende Fett oder 01 mit freien Fettsäuren versetzt und bei niedriger Temperatur extrahiert wird. 2. Embodiment of the method according to claim 1, characterized in that the fat or oil to be cleaned is mixed with free fatty acids and extracted at low temperature. 3. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass man aus den noch die Fette oder Öle enthaltenden Samen oder Früchten durch Extraktion bei niedriger Temperatur mit den betreffenden Lösungsmitteln zunächst die freien Fettsäuren und die Verunreinigungen entfernt, worauf aus dem Extra1. -tionsrückstande mit demselben oder einem anderen Lösungsmittel in üblicher Weise das Fett oder 01 bei höherer Temperatur ausgezogen wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 3. Embodiment of the method according to claim 1, characterized in that one first removes the free fatty acids and the impurities from the seeds or fruits still containing the fats or oils by extraction at low temperature with the solvents in question, whereupon the Extra1. -tion residues with the same or a different solvent in the usual way the fat or 01 is extracted at a higher temperature. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
