Description
Verfahren zur Gewinnung des durch Auslaugen von Ölsaaten oder deren Preßkuchen mit einem Gemisch aus Alkohol und Benzol oder Benzin erhaltenen Lecithins. Die Erfindung hat ein Verfahren zur Gewinnung des durch Auslaugen von Ölsaaten oder deren Preßkuchen - z. B. aus Sojabohnenmehl, Sojapreßkuchen, Leinölpreßkuchen, Maiskeimen - mit einem Gemisch aus Alkohol und Benzol oder Benzin erhaltenen Lecithins zum Gegenstande.Process for the extraction of oilseeds by leaching or their Press cake with a mixture of alcohol and benzene or gasoline obtained lecithin. The invention has a method for the extraction of oilseeds by leaching or their press cake - z. B. from soybean meal, soy press cake, linseed oil press cake, corn germ - lecithins obtained with a mixture of alcohol and benzene or gasoline for Objects.
Lecithin ist bekanntlich. gegenüber stärkerer Erwärmung äußerst empfindlich und zersetzt sich bereits teilweise bei einer Temperatur von 6o' C. Bei den früher beschriebenen Gewinnungs- und Reinigungsverfahren, nach welchen die lecithinhaltigen Stoffe mit Alkohol, sonstigen organischen Lösungsmitteln oder Mischungen mehrerer Lösungsmittel behandelt werden, sollen deshalb auch höhere Temperaturen tunlichst vermieden werden.Lecithin is well known. extremely sensitive to increased warming and already partially decomposes at a temperature of 6o'C. In the earlier described extraction and purification processes, according to which the lecithin-containing Substances with alcohol, other organic solvents or mixtures of several Solvents are treated, therefore higher temperatures should also be used wherever possible be avoided.
Es ist nun gefunden worden, daß pflanzliche Öle überraschenderweise eine Schutzwirkung auf Lecithin auszuüben vermögen. Löst man beispielsweise 01 und Lecithin mit einer Mischung, die aus Alkohol und Benzol oder Benzin besteht, aus lecithinhaltigen Ülsaaten oder deren Preßkuchen aus, so kann man den so gewonnenen Extrakt auf über ioo° C erwärmen, ohne daß eine Zersetzung zu befürchten wäre. Bei Anwendung dieses bestimmten Lösungsmittelgemisches bleiben die wasserlöslichen Kohlenhydrate, deren Entfernung aus dem Lecithin Schwierigkeiten verursacht, in dem Rückstand zurück.It has now been found that vegetable oils are surprisingly able to exert a protective effect on lecithin. Solving for example 01 and lecithin with a mixture consisting of alcohol and benzene or gasoline, of lecithin-containing Ülsaaten or the press cake, so can the extract so obtained in about ioo ° C heat without degradation would be feared. When this particular solvent mixture is used, the water-soluble carbohydrates, which are difficult to remove from the lecithin, remain in the residue.
Gegenstand der Erfindung ist nun ein Verfahren, nach welchem das in dem erwähnten ölhaltigen Extrakt enthaltene Lecithin durch Einleiten von Wasserdampf gewonnen "wird. Es scheidet sich hierbei eine sirupartige, aus Lecithin und mitggrissenem Öl bestehend Masse aus, von welcher das C51 leicht getrennt werden kann, während das gewonnene Lecithin sich in bekannter Weise reinigen läßt.The invention now relates to a method by which the in lecithin contained in the oil-containing extract mentioned by introducing steam is obtained ". A syrupy, lecithin and entrained Oil made up of bulk from which the C51 can be easily separated while the lecithin obtained can be purified in a known manner.
Untersuchungen ha@hen ergeben, daß das so erhaltene Lecithin einen Phosphorgehalt von 3,8 bis 3,9 Prozent besitzt und hinsichtlich Löslichkeit, Aussehen, Geschmack und Geruch allen Anforderungen entspricht. In bezug auf Ausbeute und Reinheit des gewonnenen Lecithins übertrifft das Verfahren alle seither angewandten Arbeitsweisen.Investigations have shown that the lecithin obtained in this way has a phosphorus content of 3.8 to 3.9 percent and meets all requirements with regard to solubility, appearance, taste and smell. With regard to the yield and purity of the lecithin obtained, the process surpasses all procedures used since then.
Die bessere Ausbeute ist darauf zurückzuführen, daß das Rohlecithin durch die Wasserdampfbehandlung weitgehend entölt wird, während andererseits das bis zum Schlusse vorhandene (51 das Lecithin mit einer schützenden Schicht umgibt und Zersetzungen des Phosphatids verhütet. Infolge seiner:höheren Reinheit ist es besonders leicht löslich.The better yield is due to the fact that the raw lecithin is largely de-oiled by the steam treatment, while on the other hand the present until the end (51 surrounds the lecithin with a protective layer and prevents decomposition of the phosphatide. As a result of it: it is higher purity particularly easily soluble.
Ein weiterer Vorteil des Verfahrens besteht darin, daß man bei der Reinigung des Rohlecithins mit geringeren Mengen Lösungsmittel auskommt also sonst, weil die Hauptmenge des (51s hereits abgeschieden ist.Another advantage of the method is that you can with the Purification of the raw lecithin with smaller amounts of solvent is otherwise possible, because the bulk of the (51s is deposited here.
Beispiel. zooo kg Sojabohnen werden mit einem Gemisch von, 75 Teilen Benzol und 25 Teilen Alkohol (g6 Volumprozent) so lange bei etwa 30° C extrahiert, bis alles t51 nahezu vollständig ausgelöst ist; dieses ist in etwa einer Munde der Fall. Die Hauptmenge des Lösungsmittels wird von der Extraktlösung abgetrieben, der ausgeschiedene Satz von clean L?brigen getrennt und der Rückstand auf 1o3° C erwärmt. Hierauf leitet man 15 Minuten lang entspannten Wasserdampf ein. Das Lecitlaiaa fällt aus und reißt etwas C51 mit, das in bekannter Weise entfernt wird.Example. zooo kg of soybeans are mixed with 75 parts Benzene and 25 parts of alcohol (g6 percent by volume) so long at about 30 ° C extracts until all t51 is almost completely triggered; this is roughly the case with one mouth. Most of the solvent is from the extract solution aborted, the excreted set of clean remaining separated and the residue warmed to 1o3 ° C. Relaxed steam is then introduced for 15 minutes. The Lecitlaiaa precipitates and carries with it some C51, which removes it in a known manner will.
Maiskeime, Leinölkuchen und andere lecithinhaltige Walsaaten oder deren Preßkuchen werden in gleicher Weise behandelt.Corn germ, linseed oil cake and other whale seeds containing lecithin or their press cakes are treated in the same way.
