Description
Verfahren zur Herstellung von Farblacken durch Reaktion des Rhamnegins
mit dem Enzym, die beide in den Früchten der Rhamnusarten enthalten sind
Es hat sich nun herausgestellt, daß ausschließlich der Kern dieser Früchte das lösliche Enzym, das »Rhamninas«, einschließt. Die Erfindung besteht daher darin, daß man unter Ausnutzung dieser Feststellung die Rhamnetinbildung durch Mischen getrennt hergestellter Auszüge aus den Kernen und der Hülle herbeiführt, von denen der erste das Enzym und der zweite das Rhamnegin ohne Enzym enthält, und der zweite Auszug durch Behandlung der Hülle mit heißem Wasser, der Fermentauszug dagegen durch Auslaugen der fein zerstoßenen Kerne mit Wasser erhalten wird.It has now been found that only the core of this Fruits include the soluble enzyme called "rhamninas". The invention exists hence the fact that, taking advantage of this finding, the formation of rhamnetin is carried out by Mixing separately produced extracts from the cores and the casing brings about, of which the first contains the enzyme and the second contains rhamnegine without enzyme, and the second extract by treating the shell with hot water, the ferment extract on the other hand, is obtained by leaching the finely crushed kernels with water.
Dein Bekannten gegenüber liefert das Verfahren nach der vorliegenden Erfindung ein vollständig reines Rhamnetin, und die Ausbeute an Lack erreicht ihren Höchstwert durch Ausnützen von Lösungen, die das ganze Glykosid und das ganze Enzym enthalten.Your acquaintance delivers the method according to the present Invention of a completely pure rhamnetin, and the yield of varnish reached theirs Maximum value by using solutions containing all the glycoside and the whole enzyme contain.
Wenn man einerseits die Fruchthülle für sich, entweder durch heißes Auslaugen oder durch Abkochen finit Wasser, auszieht und man andererseits einen Extrakt der sogenannten Körner durch Auslaugen in Wasser bereitet und dann diese beiden Flüssigkeiten zusammengießt. erhält man durch das »Rhainninas« im Auszug der Körner, das in starker K3xzentration auf das Glvkosid-Rhamnegin im Extrakt aus den Fruchthüllen einwirkt, schnell das Rhamnetin, während der Zucker (Isodulcit) aus dem Glvkosid (oder Rhamninas) in Lösung bleibt. Das Rhamnetin wird dann dekantiert, geschleudert und in kochendem Wasser gewaschen. Es ist verhältnismäßig rein und kann als grünlichgelbe Paste oder nach dem Trocknen als gelbbraunes Pulver gewonnen werden.On the one hand, if you have the fruit shell for yourself, either by hot Leaching or by boiling finite water, extracts and one on the other an extract of the so-called grains prepared by leaching in water and then Pour these two liquids together. is obtained from the "Rhainninas" in the extract the grains, which are in strong concentration on the glycoside rhamnegin in the extract acts on the fruit husks, the rhamnetin quickly, while the sugar (isodulcite) from the Glvkosid (or Rhamninas) remains in solution. The rhamnetine is then decanted, spun and washed in boiling water. It is relatively pure and can be obtained as a greenish-yellow paste or, after drying, as a yellow-brown powder will.
Anstatt das Ferment in Form des wässerigen Auszuges der Körner direkt zu verwenden, kann man dieses Ferment durch 95grädigen Alkohol ausfällen und dann den Niederschlag nach dem Trocknen an der Luft in Glvcerin auflösen. llan erhält so eine Lösung des Ferments in Glycerin, die lange ihre Wirksamkeit bewahrt. Das so zubereitete Rhamnetin kann besonders zur Herstellung von Farblacken für Lebensmittel gebraucht werden. Zu diesem Zweck wird es schließlich an einen geeigneten mineralischen Träger gebunden, z. B. basisches Aluminiumsulfat, Tonerde, Zinnoxvd mit oder ohne Beizen. Das Erzeugnis kann noch getrocknet werden, wodurch sein Volumen als Handelsware für die Gewebefärberei verringert wird.Instead of the ferment in the form of the aqueous extract of the grains directly To use, this ferment can be precipitated by 95-degree alcohol and then After drying in the air, dissolve the precipitate in glycerine. llan receives such a solution of the ferment in glycerine, which retains its effectiveness for a long time. That Rhamnetin prepared in this way can be used especially for the production of colored lacquers for food to be needed. For this purpose it is finally sent to a suitable mineral Bound carrier, e.g. B. basic aluminum sulfate, alumina, Zinnoxvd with or without Pickling. The product can still be dried, reducing its volume as a commodity for fabric dyeing is reduced.
Schließlich eignet sich dieses Rhamnetin zur Bindung mit kaustischen Alkalien (Soda, Pottasche) und gibt alkalische, wasserlösliche Salze, die direkt verwendbar sind für die Bereitung von Farblacken für Lebensmittel, z. B. als Farben für Zuckerwaren oder für das Wiedergrünfärben von Hülsenfrüchten, wenn man Bedenken hat, sie mit einem blauen Farbstoff zu behandeln, oder endlich zum Gelbfärben von Gewebe und Baumwolle.Finally, this rhamnetin is suitable for bonding with caustic Alkalis (soda, potash) and are alkaline, water-soluble salts that act directly can be used for the preparation of colored varnishes for food, e.g. B. as colors for sugar confectionery or for re-coloring legumes if you have concerns has to treat them with a blue dye, or finally to dye them yellow Fabric and cotton.
