Description
Verfahren zur Herstellung laktosefreier Milch Die Erfindung betrifft ein Verfahren zur Herstellung von laktosefreier Milch, Magermilch oder Buttermilch durch Ausfällung der Eiweißstoffe, die nach Entfernung des Milchzuckers unter Zusatz der im natürlichen Rohstoff vorhandenen Salze wieder in wäßriger Lösung suspendiert werden, und besteht darin, daß die Eiweißstoffe aus dem nur eben angesäuerten Rohstoff durch Zusatz von Decoctum Carrageen als reversibler, kolloidaler Niederschlag ausgefällt und nach Entfernung des Milchzuckers unter Verwendung von Blutserum, beispielsweise einem Blutserum der Kuh, das die gleiche Albuminlösung enthält, wieder in wäßriger Flüssigkeit suspendiert werden. An Stelle des Blutserums der Kuh kann auch mit Blutserum des Pferdes oder der Ziege gearbeitet werden.Method of Making Lactose Free Milk The invention relates to a process for the production of lactose-free milk, skimmed milk or buttermilk by precipitation of the proteins, which after removal of the lactose with added the salts present in the natural raw material are suspended again in an aqueous solution and consists in the fact that the proteins come from the raw material which has just been acidified precipitated as a reversible, colloidal precipitate by adding Decoctum carrageenan and after removing the milk sugar using blood serum, for example a cow blood serum containing the same albumin solution, again in aqueous solution Liquid to be suspended. Instead of the cow's blood serum, blood serum can also be used of the horse or the goat.
Die bisher im Verkehr vorhandenen, als zuckerfreie Milch bezeichneten Erzeugnisse waren entweder nicht zuckerfrei oder besaßen Eigenschaften, die den Namen Milch nicht rechtfertigten. Bei den bekannten Verfahren zur Entfernung der Laktose aus der Milch war es nämlich unmöglich, eine Trennung der Laktose von den Caseinen und Albuminen herbeizuführen, ohne diese zu verändern. Um das veränderte Casein in Lösung zu bringen, war daher stets ein Zusatz von Alkali erforderlich, so daß es niemals gelang, die Fällung durch Suspendierung in den Zustand zurückzubringen, in dem die ausgefällten Stoffe in der natürlichen Milch vorhanden waren.Those previously on the market, referred to as sugar-free milk Products were either not sugar-free or had properties that Name milk did not justify. In the known method for removing the It was impossible to separate the lactose from the milk To bring about caseins and albumins without changing them. To that changed Bringing casein into solution therefore always required an addition of alkali, so that it was never possible to bring the precipitation back into the state by suspension in which the precipitated substances were present in natural milk.
Dieser Nachteil wird gemäß der Erfindung beseitigt, weil es gelingt, Casein auszufällen, das nur ganz wenig verändert ist, und die Suspension in Gegenwart von Blutserum durchgeführt wird. Beim Arbeiten gemäß der Erfindung wird die unverdünnte oder mit Wasser verdünnte Milch, Magermilch oder Buttermilch schwachangesäuert, so daß eine Fällung nicht entsteht, und dann eine kleine Menge eines vorzugsweise i bis 1,3 % igen Decoctum Carrageen nach den Anweisungen von Dr. v o n L i n g e 1 s h e i m (Zeitschrift f. Hygiene und Infektionskrankheiten, Bd. 42, 1903) zugesetzt. Dadurch werden alle Eiweißstoffe aus der Milch gefällt. Der Niederschlag kann durch wiederholtes Waschen mit Wasser und Dekantieren von den geringen Mengen Säure und vom Milchzucker völlig befreit werden. Der Eiweißrückstand wird dann durch Zusatz eines der Milch entsprechend verdünnten Blutserums wieder in Suspension gebracht. Der Geschmack und der Suspensionszustand werden durch Zusatz der in der natürlichen Milch vorkommenden Salze verbessert. Bei der Verwendung von Magermilch als Ausgangsmaterial setzt man nach dieser Operation die erforderliche Menge mit Wasser gewaschenen Rahmes zu.This disadvantage is eliminated according to the invention because it is possible to precipitate casein, which is only very slightly changed, and the suspension is carried out in the presence of blood serum. When working according to the invention, the undiluted or water-diluted milk, skimmed milk or buttermilk is slightly acidified so that precipitation does not occur, and then a small amount of a preferably 1 to 1.3% Decoctum carrageenan according to the instructions of Dr. von L inge 1 sheim (Journal of Hygiene and Infectious Diseases, Vol. 42, 1903) added. This precipitates all of the proteins from the milk. The precipitate can be completely freed from the small amounts of acid and lactose by repeated washing with water and decanting. The protein residue is then put back into suspension by adding a blood serum that has been diluted appropriately for the milk. The taste and the state of suspension are improved by adding the salts found in natural milk. If skimmed milk is used as the starting material, the required amount of cream washed with water is added after this operation.
Ausführungsbeispiel Die Eiweißstoffe aus 1 1 Milch werden mit ioccm eines i bis 1,3°/o Trockenstoff enthaltenden Dekoktes von Carrageen gefällt, nachdem man zunächst die Milch mit einer Säure bis zu o,oi n angesäuert hat. Der auf diese Weise erhaltene kolloidale Niederschlag wird so lange mit Wasser gewaschen, bis das Waschwasser neutral ist und keinen :Milchzucker mehr enthält. Man vermischt den gewaschenen Niederschlag mit 5 g eines 16 g Natriumchlorid, ii g Magnesiumchlorid, i g Ferrisulfat, 5 g Kaliumsulfat, .I0 9 Dikaliumphosphät und 2 g primäres Kaliumsulfat enthaltenden Salzgemisches und setzt dann 6o ccm Blutserum zu. Schließlichwird mitWasserwiederzum Anfangsvolumen von 11 angefüllt. Alle Operationen finden bei Zimmertemperatur statt.EXEMPLARY EMBODIMENT The protein substances from 1 liter of milk are precipitated with 1 ounce of a decoction of carrageenan containing 1 to 1.3% dry matter, after the milk has first been acidified with an acid of up to 0.05. The colloidal precipitate obtained in this way is washed with water until the wash water is neutral and no longer contains lactose. The washed precipitate is mixed with 5 g of a salt mixture containing 16 g of sodium chloride, ii g of magnesium chloride, ig ferric sulfate, 5 g of potassium sulfate, 10 9 dipotassium phosphate and 2 g of primary potassium sulfate and then 60 cc of blood serum is added. Schließlichwird mitWasserwiederzum initial volume of 1 1 filled. All operations take place at room temperature.
