Description
Verfahren zur Gewinnung von Trockeneigelb und Trockeneiweiß. Den Gegenstand der vorliegenden Erfindung bildet eiri Verfahren zur Gewinnung von festem Eigelb und Eiweiß aus mit Konservierungsmitteln versetztem Eiweiß oder Eigelb, welches frei von Konservierungsmitteln- ist. Das Eiweiß und Eigelb, besonders aber das letztere, wird, wie bekannt, in großem Maße vom Auslande her eingeführt, nachdem es durch Zusatz von verschiedenen Konservierungsmitteln, unter denen hauptsächlich Salz, Benzoesäure, Borsäure o. dgl. zu nennen sind, haltbar gemacht ist. In diesem' Zustande ist das Eigelb teils aus physiologischen, teils aus gesetzlichen Gründen in Deutschland nicht zu verwenden; es ist daher notwendig, das Eiweiß oder Eigelb vor der Verwendung von den Konservierungsmitteln zu befreien. Gemäß vorliegender Erfindung geschieht dieses dadurch, daß das mit Konservierungsmitteln haltbar gemachte Eiweiß oder Eigelb zunächst durch Dialysatoren geführt und dort durch Dialyse von den Konservierungsmitteln, soweit diese dialysierbar sind, befreit wird. Handelt es sich um schwer lösliche Zusätze wie freie Benzoesäure oder freie Borsäure, so empfiehlt es sich, durch Zusatz einer äquivalenten Menge Alkali, z. B. in Form von Bikarbonat, diese Substanzen erst in ihre leicht dialvsierbaren Salze überzuführen.Process for the production of dry egg yolk and dry protein. The subject The present invention provides a method for obtaining solid egg yolk and egg white from preservative-added egg white or egg yolk, which is preservative-free. The egg whites and yolks, but especially the latter, is, as is well known, imported to a large extent from abroad after it has been through Addition of various preservatives, mainly salt, Benzoic acid, boric acid or the like are to be mentioned, is made durable. In this state is the egg yolk partly for physiological, partly for legal reasons in Germany not to use; it is therefore necessary to remove the egg whites or yolks before using them to get rid of the preservatives. According to the present invention happens this by the fact that the egg white or egg yolk preserved with preservatives first passed through dialyzers and there through dialysis of the preservatives, as far as these are dialyzable, is released. Is it difficult to dissolve? Additives such as free benzoic acid or free boric acid are recommended by adding an equivalent amount of alkali, e.g. B. in the form of bicarbonate, these substances first to be converted into their easily dialvsizable salts.
Die so frei von Konservierungsmitteln erhaltenen Eigelb- und Eiweißpräparate sind aber in diesem Zustande außerordentlich leicht verderblich und würden, wenn man sie im Vakuum o. dgl. trocknet, nicht mehr in unverdorbener Form gewonnen werden können. Dieses gelingt aber, wenn man die dialvsierten Produkte in geeigneter Weise, z. B. mittels einer Düse, verstäubt und sie in einen trockenen evtl. erwärmten Luftstrom einführt. Bei genügend langem Wege nimmt der Luftstrom die gesamte Feuchtigkeit auf und führt schließlich nur noch die festen getrockneten Teilchen ,des Eiweißes oder Eigelbes mit sich. Der Luftstrom kann dann durch Filter oder Absetzräume geleitet und die von ihm - in Staubform mitgeführte trockene Substanz auf diese Weise gewonnen werden. Man erhält so z. B. aus chinesischem gesalzenen Faßeigelb ein salzfreies unverdorbenes Trockeneigelb, das sich unbegrenzt hält.The egg yolk and protein preparations obtained in this way free of preservatives but are extremely perishable in this state and would, if if they are dried in a vacuum or the like, they can no longer be obtained in an unspoiled form can. However, this succeeds if one uses the dialed products in a suitable manner, z. B. by means of a nozzle, atomized and they in a dry, possibly heated air stream introduces. If the path is long enough, the airflow takes away all of the moisture and finally only carries the solid, dried particles, the protein or egg yolks with it. The air flow can then be passed through filters or settling rooms and the dry substance carried along by him in the form of dust was obtained in this way will. One obtains z. B. from Chinese salted drum yolks a salt-free unspoilt dry egg yolk that lasts indefinitely.
Es ist an sich bereits vorgeschlagen worden, Eibestandteile, insbesondere Eiweiß, das zu Konservierungszwecken mit Bisulfit versetzt ist, zu dialysieren. Indessen -geschah das nicht zum Zwecke der Befreiung des Eiweißes von dem Konservierungsmittel, sondern lediglich dazu, den Überschuß des Bisulfits zu beseitigen, die zur Konservierung notwendige Menge dagegen im Präparat zu belassen. Wenn man das vollkommen vom Konservierungsmittel befreite Eigelb bzw. Eiweiß mit Hilfe der üblichen langsamen Trockenmethoden (im Vakuum, in Trockenschränken) von der Feuchtigkeit befreite, so würde hierbei eine Zersetzung eintreten, diese wird aber dann vermieden, falls das Eiweiß oder Eigelb sofort nach der Dialyse in kürzester Zeit getrocknet wird, was, wie erwähnt, in der Weise geschieht, daß man der Entziehung des Konservierungsmittels sofort die Trocknung durch Verstäuben und Einführen in einen trocknen Luftstrom folgen läßt. An sich ist diese Trockenmethode auch für die Überführung von Eiinhalt in trockne Form bekannt, die Vereinigung der Entfernung des Konservierungsmittels .durch Dialyse mit der sofort darauf folgenden Trocknung durch Zerstäubung bietet jedoch erst eine Möglichkeit, den durch Zusatz von Konservierungsmitteln konservierten Eiinhalt in ein unbegrenzt haltbares und von Konservierungsmitteln freies Präparat umzuwandeln. Man kann also mit Hilfe des vorliegenden Verfahrens den aus dem Auslande stammenden konservierten Eiinhalt im Inlande derartig verarbeiten, daß ein den gesetzlichen Vorschriften entsprechendes haltbares Produkt erhalten wird.It has already been proposed per se, egg components, in particular Dialyze egg white that has been treated with bisulfite for preservation purposes. However, this was not done for the purpose of freeing the protein from the preservative, but only to eliminate the excess of bisulfite, which is necessary for preservation however, to leave the necessary amount in the preparation. If you get that completely from the preservative freed egg yolks or egg whites using the usual slow drying methods (im Vacuum, in drying cabinets) freed from the moisture, this would be a Decomposition can occur, but this is avoided if the egg white or egg yolk immediately after dialysis, what is dried, as mentioned in the way it happens that one of the Withdrawal of the preservative immediately drying by dusting and introducing into a dry air stream lets follow. In itself, this drying method is also suitable for transferring egg contents known in dry form, the association of the removal of the preservative . by dialysis with the immediately following drying by atomization but only one possibility, the one preserved by adding preservatives Egg content in an indefinitely stable and preservative-free preparation to convert. With the help of the present procedure, one can get those from abroad process the preserved egg content originating in Germany in such a way that a legal Preserved product is obtained.
