Description

Verfahren zur Herstellung von gegen bakterielle Infektionen unempfindlichem Schmelzkäse Das Verfahren bezweckt die Immunisierung von Schmelzkäse gegen die Auswirkung bakterieller Infektionen.Process for the production of insensitive to bacterial infections Processed cheese The purpose of the process is to immunize processed cheese against the effects bacterial infections.

Schmelzkäse ist wie die meisten Nahrungsmittel bakteriellen Infektionen ausgesetzt, die an diesem Blähungen hervorrufen und ihn daher ungenießbar machen. Es lag deshalb nahe, dem Schmelzkäse solche Zusätze zu machen, die die vorhandenen Bakterien abtöten bzw. das Auftreten derselben sicher unterbinden. Zu diesem Zweck sind bereits Jodide, Bromide, Benzoesäure, Wasserstoffsuperoxyd u. a. als Konservierungsmittel für Schmelzkäse vorgeschlagen worden. Von diesen Mitteln hat sich bisher Wasserstoffsuperoxyd am besten bewährt, weil es im Käse keine Fremdstoffe hinterläßt und deshalb keine Gefahr besteht, bei Verwendung dieser Verbindung gegen die in den meisten Ländern bestehenden strengen gesetzlichen Bestimmungen auf dem Lebensmittelgebiet zu verstoßen. Trotzdem stellt auch dieses Mittel keine ideale Lösung der bestehenden Aufgabe dar im Hinblick darauf, daß das Wasserstoffsuperoxyd, das im Betrieb in Form einer mehr oder weniger konzentrierten wäßrigen Lösung angewendet zu werden pflegt, eine ätzende Flüssigkeit darstellt, also nicht ganz gefahrlos zu handhaben ist und eine starke Schaumentwicklung begünstigt.Processed cheese, like most foods, is bacterial infection exposed, which cause flatulence on this and therefore make it inedible. It was therefore an obvious choice to add additives to the processed cheese in addition to the existing ones Kill bacteria or reliably prevent them from occurring. To this end are already iodides, bromides, benzoic acid, hydrogen peroxide and others. as a preservative has been proposed for processed cheese. Of these agents, hydrogen peroxide has so far been used best proven because it does not leave any foreign substances in the cheese and therefore none There is a risk of using this connection against in most countries to violate existing strict legal provisions in the food sector. Nevertheless, this remedy does not represent an ideal solution to the existing task either with a view to the fact that the hydrogen peroxide that is in operation in the form of a more or less concentrated aqueous solution tends to be corrosive Represents a liquid, so it is not completely safe to handle and a strong one Foam development favors.

Um diesen Nachteil auszuschalten, hat man auch schon den Vorschlag gemacht, das Wasserstoffsuperoxyd an eine geeignete, zur Herstellung von Schmelzsalzlösungen dienende Verbindung, wie Pyrophosphat, anzulagern. Da jedoch Pyrophosphat nur einen relativ geringen Gehalt an aktivem Sauerstoff aufnimmt, andererseits die Verwendung von Pyrophosphat aus anderen Gründen, z. B. wegen des kleinen PH-Intervalls, nur begrenzte Verwendung finden kann, so ist die angestrebte Lösung auch auf diesem Wege _ nicht in befriedigender Weise zu verwirklichen.The suggestion has already been made to eliminate this disadvantage made the hydrogen peroxide to a suitable, for the production of Molten salt solutions serving compound, such as pyrophosphate, to attach. However, since pyrophosphate only has one absorbs a relatively low content of active oxygen, on the other hand the use of pyrophosphate for other reasons, e.g. B. because of the small PH interval, only Can find limited use, the desired solution is also on this Ways _ not to be realized in a satisfactory manner.

Nach dem erfindungsgemäßen Verfahren verwendet-man zur Herstellung eines gegen bakterielle Infektionen unempfindlichen Schmelzkäses die Lösung eines Anlagerungsproduktes von Hydroperoxyd an hochviskos lösliche saure Alkali-, insbesondere Natriummetaphosphate. Man erhält diese Verbindungen, indem ma,-n ein Monoalkaliphosphat (Mei H2 P 04) oder ein Dialkalidihydrodiphosphat (Mei2 H2 P2 O,) unter Zusatz geringer Mengen freier Phosphorsäure kurze Zeit auf Temperaturen, die über dem Schmelzpunkt des Metaphosphates liegen, erhitzt, darauf die Masse abschreckt und das erhaltene Reaktionsprodukt mit Wasserstoffsuperoxydlösungen versetzt. Diese Körper besitzen einen sehr hohen Gehalt an abspaltbarem Sauerstoff, nämlich 15 % und mehr, so daß mit der zum Schmelzen der Käsemasse notwendigen Phosphatmenge eine Konzentration an aktivem Sauerstoff erreicht -wird, die gleichzeitig zur Konservierung völlig ausreichend ist. Ein weiterer Vorzug dieser Mittel liegt darin, daß sie sich ohne Schwierigkeiten in Mischung mit Ortho-, Pyro- und Polyphosphaten verwenden lassen und so die Basis einer beliebigen Anzahl von Schmelzsalzmischungen für den gesamten PH-Bereich bilden können. Im Gegensatz dazu besitzen die alkalisch reagierenden Perpyrophosphate ein hohes Puffervermögen, so daß man, um die vielfach notwendige saure pg-Einstellung der Schmelzsalzlösung zu erreichen, verhältnismäßig große Mengen anderer saurer Phosphate zufügen muß, was jedoch eine Herabsetzung der Sauerstoffkonzentration zur Folge hat. Die Permetaphosphate hingegen sind schwach sauer (pH etwa 5) und können infolge ihres geringen Pufferungsvermögens mit alkalischen Phosphaten oder anderen Schmelzsalzen, wie Citraten, auf jedes für Schmelzzwecke erforderliche pH eingestellt werden. Beispiel io kg Tilsiter Rohkäse werden unter Zusatz von 300 g einer Schmelzsalzmischung vom PH 8,5, die 35'/o eines Natriumpermetaphosphates mit einem Gehalt an aktivem Sauerstoff von 15% enthält, in bekannter Weise bei 8o° im Vakuum geschmolzen. Der so erhaltene Käse zeigt beim Lagern keinerlei bakterielle Blähungen im Gegensatz zu dem in analoger Weise, aber ohne Perphosphat geschmolzenen.According to the process according to the invention, one uses for the production processed cheese insensitive to bacterial infections is the solution of a Addition product of hydroperoxide to highly viscous soluble acidic alkali, in particular Sodium metaphosphates. These compounds are obtained by adding ma, -n a monoalkali metal phosphate (Mei H2 P 04) or a dialkaldihydrodiphosphate (Mei2 H2 P2 O,) with the addition of lower Amounts of free phosphoric acid briefly at temperatures above the melting point of the metaphosphate, heated, then quenched the mass and the obtained Reaction product mixed with hydrogen peroxide solutions. Own these bodies a very high content of removable oxygen, namely 15% and more, so that with the amount of phosphate necessary to melt the cheese mass of active oxygen -is achieved at the same time for preservation completely is sufficient. Another advantage of these remedies is that they can be used without Difficulty using mixed with ortho-, pyro- and polyphosphates and so the base of any number of molten salt mixtures for the whole PH range can form. In contrast, the alkaline reactants have Perpyrophosphate has a high buffering capacity, so that one in order to obtain the often necessary To achieve acidic pg setting of the molten salt solution, relatively large amounts have to add other acidic phosphates, which, however, reduces the oxygen concentration has the consequence. The permetaphosphates, on the other hand, are weakly acidic (pH about 5) and can due to their low buffering capacity with alkaline phosphates or other melting salts, such as citrates, to any pH required for melting purposes can be set. Example 10 kg of Tilsiter raw cheese are added with 300 g of a molten salt mixture of pH 8.5, the 35% of a sodium permetaphosphate with an active oxygen content of 15%, in a known manner at 80 ° melted in vacuum. The cheese obtained in this way shows no bacterial whatsoever on storage Flatulence in contrast to that melted in an analogous way, but without perphosphate.
