Abstract

The invention relates to a solubilisate, comprising an aqueous solution of a preservative for food, cosmetics and similar, including potassium sorbate, calcium sorbate, sodium benzoate, potassium benzoate and calcium benzoate and an emulsifier with an HLB value of 9 to 18, for example, a polysorbate.

Description

Zur Verbesserung der Haltbarkeit von Lebensmitteln, Pharmazeutika, Kosmetika und Pflegemitteln werden diesen Produkten Konservierungsmittel beigemischt, die deren Befall durch Pilze und/oder Schimmel hemmen. Weite Verbreitung als Konservierungsmittel haben Sorbinsäure und ihr Kalium- oder Kalziumsalz gefunden. Als weitere Konservierungsmittel werden die Benzoate des Natriums, Kaliums oder Kalziums vielfach für die oben genannten Produkte eingesetzt. To improve the shelf life of food, pharmaceuticals, cosmetics and care products, these products are mixed with preservatives that inhibit their infestation by fungi and / or mold. Widely used as preservatives have found sorbic acid and its potassium or calcium salt. As further preservatives, the benzoates of sodium, potassium or calcium are often used for the above-mentioned products.
Die genannten Konservierungsmittel zeigen leider nur geringe Wirksamkeit als mikrobiologischer Schutz für fettige Substanzen, und zwar wegen der geringen Löslichkeit der Konservierungsmittel in den in den eingangs genannten Produkten benutzten Fetten und Ölen. Daher haften die Mittel außen an den Fettröpfchen an und können ihre Schutzwirkung nicht in das Innere der Fettmischungen ausdehnen.Unfortunately, the preservatives mentioned have little efficacy as a microbiological protection for fatty substances, because of the low solubility of the preservatives in the fats and oils used in the products mentioned above. Therefore, the agents adhere to the outside of the fat droplets and can not extend their protective action into the interior of the fat mixtures.
Der Erfindung liegt daher die Aufgabe zugrunde, den mikrobiologischen Schutz fettiger Substanzen zu verbessern.The invention is therefore based on the object to improve the microbiological protection of fatty substances.
Zur Lösung dieser Aufgabe ist erfindungsgemäß ein Solubilisat vorgesehen, das aus einem Konservierungsmittel, welches entweder Kaliumsorbat oder Kalziumsorbat oder ein Benzoat des Natriums oder Kaliums oder Kalziums ist, Wasser und einem Emulgator mit einem HLB-Wert zwischen 9 bis 18, zum Beispiel einem Polysorbat, besteht. Dieses Solubilisat, das vorzugsweise eine gesättigte, wässrige Lösung des Konservierungsmittels enthält, ist in Fetten und Ölen leicht löslich und zur alsbaldigen Einarbeitung in die eingangs genannten Produkte, zweckmäßig innerhalb weniger Tage, bestens geeignet. Für eine längere Lagerzeit über Monate hin empfiehlt sich ein Zusatz eines oder mehrerer mitteikettiger Triglyceride oder leichter Pflanzenöle zum Solubilisat, die ein Ausfällen von Teilen des Konservierungsmittels zuverlässig verhindern.To achieve this object, the invention provides a solubilizate which comprises a preservative which is either potassium sorbate or calcium sorbate or a benzoate of sodium or potassium or calcium, water and an emulsifier having an HLB value of between 9 and 18, for example a polysorbate, consists. This solubilizate, which preferably contains a saturated, aqueous solution of the preservative, is readily soluble in fats and oils and is well suited for immediate incorporation into the products mentioned at the outset, expediently within a few days. For a longer storage period for months, it is advisable to add one or more mitigikettiger triglycerides or lighter vegetable oils to the solubilizate, which reliably prevent precipitation of parts of the preservative.
Bevorzugt ist, dass die gewichtsmäßige Menge des eingesetzten Polysorbats mindestens etwa doppelt so groß ist wie die Gewichtsanteile des Konservierungsmittels, des Wassers und gegebenenfalls der Triglyceride zusammen genommen. Als Polysorbat kommt vornehmlich das Polysorbat 80 in Betracht, wobei der Einsatz von Polysorbat 20 ein weniger viskoses Solubilisat ergibt. Das erfindungsgemäße Solubilisat kann ohne zusätzliche Arbeitsschritte in die lipophilen Bestandteile der erwähnten Endprodukte vollkommen fein verteilt und homogen eingearbeitet werden, so dass die gesamte Menge an lipophilen Substanzen in dem Endprodukt mikrobiologisch geschützt wird. Das erfindungsgemäße Solubilisat eignet sich besonders für Öle, Fette, Margarine, Wachse, Geflügelfleisch, Mayonnaise, vorgefertigte Suppenkonzentrate, Saucen, Cremes, Hautcremes und Pharmazeutika.It is preferred that the amount by weight of the polysorbate used is at least about twice as large as the weight proportions of the preservative, of the water and optionally of the triglycerides taken together. As polysorbate is mainly the polysorbate 80 in Consider, wherein the use of polysorbate 20 gives a less viscous solubilizate. The solubilizate according to the invention can be completely finely divided and homogeneously incorporated into the lipophilic constituents of the end products mentioned without additional working steps, so that the entire amount of lipophilic substances in the end product is microbiologically protected. The solubilizate according to the invention is particularly suitable for oils, fats, margarine, waxes, poultry meat, mayonnaise, prefabricated soup concentrates, sauces, creams, skin creams and pharmaceuticals.
Die Erfindung wird nachstehend anhand folgender Ausführungsbeispiele beschrieben:The invention will be described below with reference to the following embodiments:
Beispiel 1 :Example 1 :
Etwa 10 Gew% Kaliumsorbat (E 202) werden mit etwa 13 Gew% destilliertem Wasser von etwa 70 bis 75 0C zu einer gesättigten Lösung durch etwa drei- bis fünfminütiges Rühren bis zur Klarheit aufgelöst und gerührt. Sodann werden in die Lösung etwa 77 Gew% Polysorbat 80 gegeben und in der genannten Wärme so lange gerührt, bis das Gemisch Homogenität und Transparenz erreicht hat.About 10% by weight of potassium sorbate (E202) is dissolved with about 13% by weight of distilled water of about 70 to 75 ° C to a saturated solution by stirring for about three to five minutes until clear and stirred. Then, about 77% by weight polysorbate 80 are added to the solution and stirred in the said heat until the mixture has reached homogeneity and transparency.
Dieses Solubilisat enthält somit 10 Gew% fett- und wasserlösliches Kaliumsorbat.This solubilizate thus contains 10% by weight of fat-soluble and water-soluble potassium sorbate.
Beispiel 2:Example 2:
In die gesättigte wässrige Lösung von Kaliumsorbat nach Beispiel 1 werden etwa 10 Gew% mittelkettige Triglyceride gegeben und bei der angegebenen Temperatur etwa fünf Minuten gerührt, bis zu einer homogenen, trüben Emulsion. Diese Emulsion wird mit 67 Gew% Polysorbat 80 gemäß Beispiel 1 bis zur Transparenz verrührt.In the saturated aqueous solution of potassium sorbate according to Example 1, about 10% by weight medium chain triglycerides are added and stirred at the indicated temperature for about five minutes, until a homogeneous, turbid emulsion. This emulsion is stirred with 67% by weight polysorbate 80 according to Example 1 until transparent.
Beispiel 3: 10 Gew% Kaliumsorbat werden wieder mit etwa 13 Gew% destilliertem Wasser bei 70 bis 75 °C bis zur Klarheit verrührt. Der Lösung werden etwa 10 Gew% eines leichten Pflanzenöls, wie beispielsweise Sonnenblumenöl, Olivenöl, Distelöl, hinzugegeben und bei der genannten Temperatur bis zur Homogenität der Emulsion gerührt. Diesem Gemisch werden etwa 67 Gew% Polysorbat 80 zugegeben und in der Wärme so lange gerührt, bis Transparenz erhalten wird. Beispiel 4:Example 3: 10% by weight of potassium sorbate are stirred again with about 13% by weight of distilled water at 70 to 75 ° C until clear. About 10% by weight of a light vegetable oil, such as sunflower oil, olive oil, safflower oil, is added to the solution and stirred at the temperature mentioned until the emulsion is homogeneous. About 67% by weight polysorbate 80 is added to this mixture and stirred in the heat until transparency is obtained. Example 4:
Etwa 10 Gew% Natriumbenzoat werden in etwa 20 Gew% Wasser bei 70 bis 750C zu einer gesättigten, klaren Lösung durch Rühren aufgelöst. Diese Lösung wird bei der bezeichneten Temperatur mit etwa 70 Gew% Polysorbat 80 bis zur 5 Klarheit, Homogenität und Transparenz verrührt.About 10% by weight of sodium benzoate is dissolved in about 20% by weight of water at 70 to 75 ° C. to a saturated, clear solution by stirring. This solution is stirred at the designated temperature with about 70% by weight polysorbate 80 to clarity, homogeneity and transparency.
Beispiel 5:Example 5:
Etwa 10 Gew% Natrium-Benzoat werden wie in Beispiel 4 in etwa 20 Gew% destilliertem Wasser bei einer Temperatur von etwa 70 bis 75 0C bis zu einer I0 gesättigten, klaren Lösung verrührt. Der Lösung werden etwa 10 Gew% mittelkettige Triglyceride zugegeben und bei der angegeben Temperatur bis zur Homogenität der Emulsion weiter gerührt. Schließlich werden ca. 60 Gew% Polysorbat 80 hinzugegeben und bei der angegebenen Wärme bis zur Klarheit und Transparenz gerührt.About 10% by weight of sodium benzoate are stirred as in Example 4 in about 20% by weight of distilled water at a temperature of about 70 to 75 0 C until a I 0 saturated, clear solution. About 10% by weight of medium-chain triglycerides are added to the solution and stirring is continued at the indicated temperature until the emulsion is homogeneous. Finally, about 60% by weight polysorbate 80 is added and stirred at the indicated heat until clear and transparent.
I5 I 5
An Stelle des Natrium-Benzoats können bei gleichen Gewichtsverhältnissen Kalium-Benzoat oder Kalzium-Benzoat eingesetzt werden. Auch hier verdient Polysorbat 80 der Vorzug, während der Einsatz von Polysorbat 20 ein weniger viskoses Produkt ergibt. 0Instead of the sodium benzoate, potassium benzoate or calcium benzoate can be used at the same weight ratios. Again, polysorbate 80 is preferred, while the use of polysorbate 20 gives a less viscous product. 0
Die für die Erfindung verwendbaren Pflanzenöle sind von üblicher Art. Für die Triglyceride kann beispielsweise das unter der Marke MIGLYOL 812 bei Caesar & Lorentz GmbH, Hilden, erhältliche Gemisch eingesetzt werden, das im Wesentlichen Octansäure und Dekansäure sowie wenig Dodecansäure enthält. 5 The vegetable oils which can be used for the invention are of conventional type. For the triglycerides it is possible, for example, to use the mixture obtainable under the trade name MIGLYOL 812 from Caesar & Lorentz GmbH, Hilden, which essentially comprises octanoic acid and decanoic acid and a little dodecanoic acid. 5
Die angegebenen Temperaturwerte sind für die Gewinnung der Solubilisate besonders günstig. Erhöht man die Temperatur beispielsweise auf 85 0C, ist der Sättigungsgrad des Konservierungsstoffes zwar formell höher, in praxi jedoch niedriger wegen des Wasserabdampfes während des Rührens. Erniedrigt man die 0 Temperatur auf etwa 60 0C, ist nicht nur der Konservierungsmittelgehalt der Lösung kleiner, sondern es muss auch länger als etwa fünf Minuten gerührt werden.The specified temperature values are particularly favorable for the recovery of the solubilizates. Increasing the temperature, for example, to 85 0 C, the degree of saturation of the preservative is formally higher, in practice, but lower because of Wasserabdampfes while stirring. If the temperature is lowered to about 60 ° C., not only is the preservative content of the solution smaller, but it must also be stirred for more than about five minutes.
Die angegebenen Gewichtsprozente beziehen sich auf das Gesamtgewicht des fertigen Solubilisats (= 100 Gew%). The stated percentages by weight are based on the total weight of the finished solubilisate (= 100% by weight).
