Description

Herstellung von Eiweißstoffen Man hat bereits vorgeschlagen, Eiweißstoffe in Wasser quellbar oder wasserlöslich zu machen durch Abbau mit Säure oder Alkalien. Hochmolekulare Eiweißstoffe ließen. sich aber bisher in Wasser nicht lösen.Manufacture of protein substances One has already proposed protein substances to be made swellable or water-soluble in water by decomposition with acids or alkalis. High molecular weight proteins left. but so far do not dissolve in water.

Nach der vorliegenden Erfindung werden in Wasser stark quellende und sich schließlich lösende Eiweißstoffe hergestellt, indem hochmolekulares Eiweiß aus Muskelfasern tierischer Herkunft, zweckmäßig von frischen Wassertieren, vorzugsweise von Fischen, im wäßrigen Medium mit Harnstoff, vorzugsweise unter Druck, erhitzt wird.According to the present invention, strongly swelling in water and Finally dissolving proteins produced by adding high molecular weight protein from muscle fibers of animal origin, preferably from fresh aquatic animals, preferably of fish, heated in an aqueous medium with urea, preferably under pressure will.

Als Ausgangsgut kann alles Eiweiß aus Muskelfleisch von Kaltblütern. Moder Warmblütern, z. B. von Wassertieren, wie Fischen, Walen oder Landtieren, verwendet werden. Beispiel In ioo 1 Wasser werden io kg Eiweiß, welches nach bekannten Verfahren aus Fischfleisch hergestellt ist, aufgeschlämmt und hierzu io kg Harnstoff gefügt. Das Gemisch wird zweckmäßig unter Verrühren im Druckbehälter bei etwa o,5 bis 7 atü i Stunde erhitzt. Es findet eine Entwicklung von Ammoniak statt. Nach Beendigung des Aufschlusses wird eine gallertartige Masse erhalten, die in Wasiser leicht quillt und sich leicht auflöst. Wenn man hochmolekulares Eiweiß mit Alkalien abbaut, um es in Lösung zu bringen, wird eine Molekülverkleinerung erzielt und damit eine Beeinträchtigung des Hauptwertes des Fischeiweißes. - Nach der vorliegenden Erfindung tritt dagegen nur ein geringfügiger Abbau des Eiweißmoleküls ein. Offenbar verbindet sich das Eiweiß mit den Zersetzungsprodukten des Harnstoffes, vielleicht mit Biuret oder Kohlenoxydverbindungen zu einer neuartigen Verbindung, deren chemische Konstitution noch nicht geklärt werden konnte. Das erhaltene Erzeugnis zeigt aber Eigenschaften, die mehr denjenigen des Eiweißes als denjenigen des Harnstoffes gleichen. Die Erzeugnisse nach der vorliegenden Erfindung können u. a. als Textilhilfsmittel und Appreturmittel mit Vorteil verwendet werden.Any protein from the muscle meat of cold-blooded animals can be used as starting material. Moder warm-blooded animals, e.g. B. used by aquatic animals such as fish, whales or land animals will. EXAMPLE 100 kg of protein are added to 100 l of water, which is obtained according to known processes is made from fish meat, slurried and added 10 kg of urea. The mixture is expediently stirred in a pressure vessel at about 0.5 to 7 heated for 1 hour. There is an evolution of ammonia. After completion After the digestion, a gelatinous mass is obtained which swells slightly in Wasiser and dissolves easily. If you have high molecular weight protein with alkalis degrades to bring it into solution, a molecular reduction is achieved and thus an impairment of the main value of fish protein. - According to the present In contrast to the invention, only a slight breakdown of the protein molecule occurs. Apparently the protein combines with the decomposition products of urea, perhaps with biuret or carbon oxide compounds to a new type of compound, its chemical Constitution could not yet be clarified. However, the product obtained shows Properties more like those of protein than those of urea. The articles of the present invention may include as a textile auxiliary and finishing agents can be used to advantage.
