Description
Verfahren zur Herstellung von kolloidalem Lecithin Das Lecithin kommt in der Natur, z. B. im Eigelb, in kolloidaler Form vor. Es wird hier sowohl von flüssigen Fetten wie flüssigen Eiweißstoffen begleitet, die als Schutzkolloide wirken können. Das Lecithin, das technisch mit Lösungsmitteln vom Eiweiß und Fett getrennt wird, hat seine kolloidale Natur und Emulsionsfähigkeit wenigstens teilweise verloren, und es ist schwierig, Lecithin in völlig homogener, kolloidaler oder emulgierter Form dem Körper zuzuführen.Method of Making Colloidal Lecithin The lecithin comes in in nature, e.g. B. in egg yolk, in colloidal form. It is here by both liquid fats such as liquid proteins, which act as protective colloids can. The lecithin, which is technically separated from the protein and fat using solvents has lost its colloidal nature and emulsifiability at least partially, and it is difficult to make lecithin completely homogeneous, colloidal or emulsified To supply form to the body.
Aus Patentschriften ist es bekannt, daß Glycerin bei gewöhnlicher Temperatur oder zweckmäßiger in der Wärme Lecithin löst. Diese Lösungen lassen sich in sehr konzentrierter Form darstellen und zeigen dann die Eigenschaften kolloider oder einfacher-Emulsionen, die jedoch auf rein mechanischem Wege nur schwierig völlig homogen zu erhalten sind. Es wurde nun beobachtet, daß man schnell und vollständig homogenes, kolloidales Lecithinglyoerin erhält, wenn man wasserfreiem Glycerin z bis 3 Prozent reine Gelatine zusetzt und unter Erwärmen in ihm löst. Die zähen Massen, die sich sonst nur sehr langsam und unvollständig unter starleer mechanischer Verreibung vereinigen, werden in kürzester Frist wie durch ein emulgierendes Ferment homogen, weich und kolloidal. Das entstandene Produkt, das hei gleichem Lecithin- und Glyceringehalt nicht über r Prozent Gelatine enthalten braucht, gibt beim Vermischen mit Zuckersi:rupen, z. B. Malzextrakt, sofort eine kolloidale Emulsion, die sich auch bei sehr langem Stehen nicht entmischt, was praktisch von Bedeutung ist.From patents it is known that glycerol with ordinary Dissolves lecithin at temperature or, more appropriately, in heat. These solutions can be in a very concentrated form and then show the properties of colloids or simple emulsions, which, however, are difficult to achieve completely by purely mechanical means can be obtained homogeneously. It has now been observed that one can quickly and completely homogeneous, colloidal lecithin glycerin is obtained when using anhydrous glycerin z Add up to 3 percent pure gelatin and dissolve in it while warming. The tough masses which is otherwise only very slowly and incompletely under rigid mechanical trituration combine, become homogeneous in the shortest possible time as if by an emulsifying ferment, soft and colloidal. The resulting product, that is, the same lecithin and glycerin content does not need to contain more than r percent gelatine, gives when mixed with sugar syrup, z. B. malt extract, immediately a colloidal emulsion, which is also used for a very long time Are not separated, which is of practical importance.
Diese Beobachtungen weisen darauf hin, daß der Eiweißstoff des Eigelbs, den \,#ir in seiner denaturierten Form als Lecithalbumin oder Vitellin kennen, in seiner ursprünglichen nativen Form, die er im natürlichen Eigelb besitzt, die Rolle des Schutzkolloids und emulgierenden Mittels für das natürliche Lecithin spielt.These observations indicate that the protein in the egg yolk, den \, # ir know in its denatured form as Lecithalbumin or Vitellin, in its original native form, which it possesses in the natural yolk, the role the protective colloid and emulsifying agent for the natural lecithin.
Die Anwendung anderer Stoffe, die wie Gelatine sonst als Emulgierungsmittel für wasserhaltige Emulsionen angewandt werden, wie die Gummiarten, sind für den vorliegenden Zweck weniger geeignet, da sie einmal körperfremde Stoffe darstellen und außerdem nicht die spezielle Affinität zum wasserfreien Glycerin zeigen wie die Gelatine. In dem vorliegenden Falle macht sich sowohl diese Affinität wie auch die Affinität des Lecithins zum Glycerin geltend.The use of other substances, such as gelatin, otherwise used as an emulsifying agent for water-based emulsions, like the rubber types, are for the less suitable for the present purpose, as they represent exogenous substances and also do not show the special affinity for anhydrous glycerine as the gelatin. In the present case, both this affinity and the affinity of the lecithin to the glycerin applies.
