Die Konservierung von ausgeschlagenem frischen Eigelb ist bis jetzt noch nicht in befriedigender Weise gelungen. Man benutzte seither zur Konservierung Chemikalien, wie Formalin, Borsäure, Benzoesäure, Salizylsäure, schweflige Säure und dergl., sowie deren Derivate und Salze, die jedoch alle mehr oder weniger vom Standpunkte der Nahrungsmittelchemie aus zu beanstandenThe preservation of beaten fresh egg yolks is not yet in succeeded in a satisfactory manner. Since then, chemicals have been used for preservation, such as Formalin, boric acid, benzoic acid, salicylic acid, sulphurous acid and the like., As well as their derivatives and salts, but all of them more or less objectionable from a food chemistry standpoint
ίο sind. Außerdem benutzte man Kochsalz in hohen Prozentsätzen (etwa 15 Prozent), wo-ίο are. In addition, table salt was used in high percentages (around 15 percent), where-
' durch das Eigelb ebenfalls für viele Zwecke unbrauchbar wurde.'the yolk also made it unusable for many purposes.
Ein anderes brauchbares Konservierungs-Another useful preservative
mittel für Eigelb ist Spiritus (Äthylalkohol) in Mengen von 8 bis 10 Prozent, das bekannteste Beispiel für dessen Anwendung dürfte der Eierkognak sein. Der Anwendung von Äthylalkohol im großen Maßstabe steht aber der Umstand entgegen, daß er sich nur im Zollihlande verwenden läßt, weil damit konserviertes Eigelb dem hohen Zollsatz von 150 Mark pro 100 kg beim Import aus dem Auslande unterliegt und gerade das Ausland der Hauptproduzent von Eigelb ist. Es wäre nun das nächstliegende, an Stelle von Äthylalkohol den Methylalkohol zur Konservierung von Eigelb zu verwenden, da dieser zollfrei eingeführt werden darf und damit versetztes Eigelb also nicht dem hohen Zollsatz für »Branntwein« unterliegt.The best-known agent for egg yolks is spirit (ethyl alcohol) in quantities of 8 to 10 percent Eggnog is an example of its use. The use of ethyl alcohol on a large scale is available but the fact that it can only be used in Zollihland because with it preserved egg yolk to the high tariff of 150 marks per 100 kg when imported from the Abroad is subject and foreign countries are the main producers of egg yolks. It The next thing would be, instead of ethyl alcohol, methyl alcohol for preservation of egg yolk to use, as this can be imported duty-free and thus So displaced egg yolk is not subject to the high tariff for "brandy".
Methylalkohol hat aber den großen Fehler, daß er das damit in Mengen von 8 bis 10 Prozent und mehr versetzte Eigelb nach einiger Zeit zum Gerinnen bringt, so daß es nach Ablauf einiger Wochen vollständig zur Gallerte und für viele Zwecke unbrauchbar wird.But methyl alcohol has the big mistake that it can be used in quantities of 8 to 10 percent and more mixed egg yolks coagulate after a while, so that it after a few weeks completely to jelly and useless for many purposes will.
Es wurde nun gefunden, daß sich diese Gerinnung fast ganz vermeiden läßt, wenn man dem Eigelb geringe Mengen von Stoffen zusetzt, die geeignet sind, das im Eigelb enthaltene Ovovitellin zu lösen, also z. B. Neutralsalze, Alkalien, Älkalikarbonate oder auch Säuren (vefgl. Hammars ten, Lehrbuch der physiologischen Chemie, 1899, Seite 29 und 30, unter Globulin, sowie Seite 384 unter Ovovitellin). Es ist dabei einerlei, ob man diese Stoffe dem Eigelb selbst oder dem Methylalkohol oder auch der fertigen Mischung von Eigelb mit dem Methylalkohol zusetzt. Auf diese Art konserviertes Eigelb ist sehr lange haltbar, bleibt flüssig, d. h. es behält ungefähr die Konsistenz von frischem Eigelb und ist wegen der leichten Flüchtigkeit des Methylalkohole (Siedepunkt 660C.) zu vielen Zwecken verwendbar. Die außer dem Methylalkohol noch zugesetzten Mengen von Salzen, Säuren oder Alkalien sind so unbedeutend, daß sie bei der Verwendung des Eigelbs' nicht in Betracht kommen.It has now been found that this coagulation can be almost completely avoided if small amounts of substances are added to the egg yolk which are suitable for dissolving the ovovitellin contained in the egg yolk, e.g. B. neutral salts, alkalis, alkali carbonates or acids (vefgl. Hammars th, Textbook of Physiological Chemistry, 1899, pages 29 and 30, under globulin, and page 384 under Ovovitellin). It does not matter whether these substances are added to the egg yolk itself or to the methyl alcohol or to the finished mixture of the egg yolk with the methyl alcohol. Egg yolk preserved in this way has a very long shelf life, remains liquid, ie it retains approximately the consistency of fresh egg yolk and can be used for many purposes due to the high volatility of methyl alcohols (boiling point 66 ° C.). The amounts of salts, acids or alkalis added in addition to the methyl alcohol are so insignificant that they cannot be used when using the egg yolk.
ι. ι kg flüssiges Eigelb versetzt man mit 80 bis 100 g Methylalkohol, in welchem 1 bis 2 g Weinsäure oder Zitronensäure gelöst sind und mischt gut durch,ι. ι kg of liquid egg yolk are added 80 to 100 g of methyl alcohol in which 1 to 2 g of tartaric acid or citric acid are dissolved and mixes well,
2. In ι kg flüssigem Eigelb löst man etwa io g Kochsalz auf und gibt dieser Lösung 80 bis 100 g Methylalkohol zu.2. About 10 g of table salt are dissolved in ι kg of liquid egg yolk and 80 to 100 g of methyl alcohol are added to this solution.
3. In ι kg flüssigem Eigelb löst man 1 bis 2g Natr. bicarbonic. auf und gibt 80 bis 100 g Methylalkohol zu.3. Dissolve 1 to 1 kg of liquid egg yolk 2g of sodium bicarbonic. and gives 80 to 100 g Methyl alcohol too.
Claims (1)
