Description

Verfahren zur Herstellung von Milchzucker aus Molke Die Erfindung liegt auf dem Gebiet der Verfahren zur Herstellung von Milchzucker aus nicht enteiweißter und nicht entsalzener Molke auf chemischem Wege. Hierzu ist bereits die Anwendung -eines speziellen Alkali-Metall-Tetraphosphates vorgeschlagen worden, im besonderen eines Tetranatriumpho.sphates. Die Verwendung von Natriummeta- und polyphosphaten wird nach diesem Vorschlag als unbrauchbar abgelehnt.Process for the production of milk sugar from whey The invention lies in the field of processes for the production of lactose from non-deproteinized and non-desalinated whey chemically. The application for this is already available -a special alkali metal tetraphosphate has been proposed, in particular of a Tetranatriumpho.sphates. The use of sodium meta- and polyphosphates is rejected as unusable after this proposal.

Für das Enteiweißen von Molke, für :das Gewinnen von Milchzucker, aus Süßmolke, ist auch bereits vorgeschlagen worden, der Molke Mutterlauge vor oder nach der Entfernung der Hauptmenge des Eiweißes polymere Phosphorsäure oder deren Salze zuzusetzen, also nach Eindicken und Kristallisation.For the de-proteinification of whey, for: the extraction of milk sugar, from sweet whey, it has also already been proposed to make mother liquor before or from whey after the removal of most of the protein, polymeric phosphoric acid or its Adding salts, i.e. after thickening and crystallization.

Ein anderes Verfahren fällt das in der Molke enthaltene Calcium mittels Natriumpyrophosphat aus und trennt es durch Zentrifugieren ab. Anschließend wird dann -die Molke mit Natriumhexaphosphat versetzt, eingedickt und kristallisiert.Another method is to remove the calcium contained in the whey by means of Sodium pyrophosphate and separates it by centrifugation. Then will then -the whey is mixed with sodium hexaphosphate, thickened and crystallized.

Nach .der Erfindung wird -die Molke ohne vorherige Entfernung von Eiweiß und Salzen unter Zusatz geringer Mengen von Phosphorsäuresalzen derart verarbeitet, daß hier 0,1 Gewichtsprozent Natriumtripolyphosphat, -trimetaphosphat oder -hexametaphosphat, zugesetzt wird, worauf nach üblicher Eind.ikkung und Kristallisierung der Milchzucker abgesetzt und mit schwachprozentiger Natriummetaphosphatlösung gewaschen wird.According to the invention -the whey without prior removal of Protein and salts with the addition of small amounts of phosphoric acid salts processed in such a way that that here 0.1 percent by weight sodium tripolyphosphate, trimetaphosphate or hexametaphosphate, is added, whereupon after the usual thickening and crystallization of the lactose is settled and washed with weak percent sodium metaphosphate solution.

Dieses Verfahren zur Herstellung von Milchzucker verläuft besonders vorteilhaft, wenn zwecks weiterer Reinigung der Milchzucker in an sich bekannter Weise aufgelöst, mit Aktivkohle und/oder Kieselgur behandelt, filtriert und umkristallisiert oder sprühgetrocknet wird.This process for the production of milk sugar is special advantageous if, for the purpose of further purification, the lactose is known per se Way dissolved, treated with activated charcoal and / or kieselguhr, filtered and recrystallized or spray dried.

Durch die geringen Mengen der zugesetzten besonderen Salze ist es möglich, .das Gleichgewicht der Molkensalze während der Milchzuckerfabrikation zu erhalten und mithin eine Koagolierung des Albumins und der Molkensalze zu verhindern.Because of the small amounts of the special salts added, it is possible to .the equilibrium of the whey salts during the milk sugar production and thus to prevent coagulation of the albumin and the whey salts.

Unter Aufwand sehr geringer Mittel wird nach der Erfindung ein Milchzucker ohne Fällung des Albumins und ohne Fällung der Molkensalze von besonderer Reinheit hergestellt.According to the invention, a milk sugar is produced with very little expenditure without precipitation of albumin and without precipitation of whey salts of particular purity manufactured.

Beispiel In 1000 1 Molke werden 400 g Natriummetaphosphat gelöst, die Molke wird im Verhältnis etwa 11 : 1 eingedickt, -der Milchzucker kristallisiert sodann rein aus.Example 400 g of sodium metaphosphate are dissolved in 1000 l of whey, the whey is thickened in a ratio of about 11: 1, -the milk sugar crystallizes then purely out.
