Verfahren zur Herstellung von Trockenpräparaten aus physiologisch aktive Verbindungen enthaltenden Ölen.
Gegenstand der Erfindung ist ein Verfah ren, welches die Möglichkeit ersehliesst, diäte- tisch oder therapeutisch wertvolle, physiologisch aktive Verbindungen enthaltende C) le, wie beispielsweise Konzentrate der als Vitar mine F beka. nnten essentiellen Fettsäuren, Lebertrankonzentrate,öligeLösungenfettlös- licher Vitamine, durch Bildung einer Emulsion und anschliessende Entwässerung in troekene, pulverförmige Produkte überza- führen, welche entwässerte, reversible Emulsionen darstellen, die mit Wasser verrührt, das betreffende 0l wieder in den Zustand einer fein dispersen, flüssigen Emulsion bringen.
Das erfindungsgemasse Verfahren, zur Herstellung von diätetischen oder pharmazeu tisehen Troekenpräparaten aus physiologiseh aktive Verbindungen enthaltenden Ölen ist dadurch gekennzeiehnet, dass das betreffende e 61 mittels einer wässerigen Lösung eines nativen Albumins in eine Emulsion, zweckmässig vom Typus O1-in-WATasser, übergeführt wird, wobei Additionsverbindungen vom Typus der Lipoproteide entstehen. Die erhaltene Emulsion wird sodann durch ein schonendes Trock nungsverfahren entwässert und in ein pulverförmiges Endprodukt übergeführt, welches befähigt ist,
nach Zusatz einer wässerigen Flüssigkeit das enthaltene 61 wieder in den Zustand einer feinen wässerigen Dispersion überzuführen.
Unter den gewählten Bedingungen bilden sich zwischen dem Albumin und den Lipoiden Additionsverbindungen vom Typus der Lipoproteide. Dank der Bildung soleher Additionsverbindungen bleibt das 0l beim Trocknen der Emulsion als disperse Phase fixiert. Das Vorhandensein dieser Korper ist daher die entseheidende Voraussetzung, dass eine solche Emulsion überhaupt getrocknet werden kann, ohne dass das 01 aus dem Verband austritt.
Die Fixierung des Ols im dispersen Zustand ist unerlässlich zur Erreichung der reversiblen Emulsionseigenschaften des Trockenpräpara- tes.
Diese Additionseigensehaften des Albu- mins können durch verschiedene Zusätze zu optimalen Effekten ergänzt werden. So kann ein Zusatz von Harnstoff von besonderer Bedeutung werden, da diese Verbindung beispielsweise befähigt ist, mit Fettsäuren stabile, kristallisierbare Addukte zu bilden.
Weiter hat es sich je nach Art des verwendeten Öls als zweckmässig erwiesen, wenn das Additionsvermogen des Albumins durch Zusätze von Eiweisshydrolysaten ergänzt wurde, da auch diese Stoffe zur Bildung von lipo proteidähnliehen Addukten befähigt sind.
Neben dieser primären Bildung von komplexen Additionsverbindungen können als Stabilisierungsmittel entsprechend der ge- wünschten Emulsionseigenschaften entweder relativ grosse Mengen an niedermolekularen Kohlehydraten, wie Saccharose, Glucose, Fructose, Lactose, Maltose und niedere Dextrine oder kleinere Mengen hochmolekularer Kolloidstoffe vom Kohlehydrat, oder Eiwei#- typus wie Algine und Alginate, Pektine, Carabin, Dextrine, Gelatine usw., sowie Kombinationen von hoch-und niedermolekularen Kohlehydraten, verwendet werden.
Versuehe zeigten, dass nach dem letztgenannten Verfahren hergestellte Emulsionen bei einem ausreichend hohen Geha. lt der wässerigen Phase an bestimmten Kohlehydraten durch schonende Trocknungsverfahren sich relativ leicht entwässern lassen und pulverformige Produkte liefern, welche durch Behandlung mit Wasser das Öl wieder in den Zustand der feinen wässerigen Dispersion überführen und dies unter Bewahrung der vollen urspriinglichen physiologischen Akti vität des verwendeten Öls.
Es hat sich ferner gezeigt, dass an Stelle oder kombiniert mit bestimmten Zuckerarten andere Kohlehydrate, zum Beispiel Dextrine, Stärken, Hemizellulosen, mit Vorteil der wässerigen Phase der Emulsion zugesetzt wer- den können. In der vorgesehenen hohen Konzentra. tion wirken insbesondere Glueose und Dextrine und in einem gewissen Ausmass auch Saccharose als Antioxydans für die sauer- stoffempfindlichen Komponenten.
Als spezifisch wirkende Antioxydantien natürlicher Herkunft, die weiter zugesetzt werden können, eignen sich speziell gut Ascor- bisäure sowie andere, das Redoxpotential regulierende Substanzen wie Cystein, Gluta- thion usw. und auch Phosphatide, wie z. B.
Lecithin.
Einige der versuchsweise hergestellten Trockenpräparate waren ziemlich stark hygro- skopisch. Dieser Nachteil kann dadurch beseitigt werden, dass der wässerigen Phase eine verhältnismä#ig gro#e Menge organischer Kolloidstoffe, wie Stärke, bestimmte Dextrine, Hemizellulosen oder Gelatine zagesetzt wer- den und der Gehalt an Glucose und Lactose eher niedrig gehalten wird.
Die Versuche zeigten, dass auf diese Art Lebertrankonzentrate, Konzentrate essentieller Fettsäuren, hochwertige Keimlingsole sowie ölige Losungen der fettlösliehen Vitamine A, D und E in Troekenprä. parate mit den ge- nannten Vorzügen übergeführt werden können. Hierbei besteht die Möglichkeit, der wässerigen Phase der Emulsion solehe Wirk- stoffe wie Vitamin C und Vitamine des B Komplexes sowie essentielle Aminosäuren, bestimmte Spurenelement oder andere Wirk- stoffe zu addieren und dadurch in das Trokkenpräparat überzuführen.
Als Albumin kann z. B. Lactalbumin oder Ovalbumin verwendet werden. Vorzugsweise werden solehe Albumin-Präparate verwendet, welche die natürliehen, oberflächenaktiven Begleitstoffe sowie dispergierend wirkende na türliche Salze des betreffenden Ausgangs- materials enthalten. Ein derartiges Lactalbu min-Präparat kann z. B. aus einem Milchpul- ver, Molkenpulver oder direkt aus Milch ge- wonnen werden.
Beim erfindungsgemässen Verfahren kann die Art und Menge der Zusätze in verhältnis- mässig weiten Grenzen wunschgemäss variiert werden. Es lassen sich Trockenpräparate mit einem Ölgehalt bis etwa 30 /o, berechnet vom Gesamtgewie. ht, herstellen..
Bei der technischen Durchfiihrung des erfindungsgemässen Verfahrens sind als seho nende Trocknungsverfahren zur Entwässe ning der Emulsion verwendbar : Zerstäu bungstroeknung,'Walzentrocknung, Vakuum- Troeknungsverfahren Die Walzentroeknung hat den Vorteil, eine geringere Oberfläche des Gutes der Einwirkung des Luftsauerstoffes auszusetzen als das Zerstäubungsverfahren.
Speziell geeignet ist die Vakuum-Walzentroek nung, weil dabei die Zersetzungs-und Oxy- dationsgefahr der empfindliehen Wirkstoffe auf ein Minimum reduziert wird und die Lös lichkeit des Produktes maximal gut ist. Sehr vorteilhaft ist auch das Trocknen in einer inerten Gasatmosphäre. Die Wahl des Trock nungsverfahrens riehtet sich nach der Art des Trockengutes, der Empfindlichkiet des Wirkstoffes und den Anforderungen des Produktes.
Das erfindungsgemässe Verfahren wird durch folgendes Beispiel erläutert :
Beispiel: Konzentrat essentieller Fettsäuren (Vitamin F) 75 g Lactalbumin (ein aus Molkenpulver hergestelltes Präparat, welches die oberflächenaktiven Begleitstoffe des Albumins enthält) 20 g Harnstoff 24 g Saccharose 150 g Glucose 50 g Lösliehe Getreidestärke 80 g Ascorbinsäure l g Dest. Wasser 600 g
1000 g
In einem Teil des destillierten Wassers wurde das Laetalbumin, der Harnstoff, die Saccharose, Glueose und die Ascorbinsäure, im andern Teil des Wassers die Stärke aufgelost.
Das Vitamin-F-Ol wurde mit einem Vibromischer in der zuckerhaltigen Albumin- losung emulgiert und die erhaltene Emulsion homogenisiert. Sodann wurde die heisse Stärkelösung mit der auf dieselbe Temperatur erwärmten Emulsion gut vermischt, wobei eine Additionsverbindung vom Typus des Lipoproteide e-ntstand.
Die Emulsion wurde dann in einem Va kuum-Walzentroekner entwässert. Das pulverformige Troekenpräparat lieferte durch Behandlung mit Wasser eine feine wässerige Dispersion der essentiellen Fettsäuren.
Währendfür die Walzentrocknung eine Homogenisierung der Emulsion zweckmä#ig und vorteilhaft ist, kann eine solche bei An wendung des Sprüh-Trockenverfahrens unterbleiben, da die Zerstäubung eine Homogeni- sierung der Emulsion herbeiführt.
Ein Teil, der erhaltenen Emulsion wurde in einem Dünnsehieht-Vakuumtroekner bei einem Druck von 100 bis 0, 1 mm Hg und einer Temperatur von etwa 20 bis 60 C entwässert. Das trockene Endprodukt wird je nach späterer Verwendungsart in ein mehr oder weniger feines Pulver gemahlen. Mit der etwa 10fachen Menge Wasser behandelt, wurde eine wässerige Dispersion des Öls erhalten, die aus Tröpfchen von der Grossenord- nung 1 bis 2 bestand. Für die gute Haltbarkeit des Trockenpräparates soll der Wassergehalt nicht mehr als 3 bis 4 % betragen.
Die erfindungsgemäss hergestellten Trokkenpräparate können in dosierte Kapseln, Tabletten oder Dragées verpresst oder aueh in Pulverform gewissen Nähr-, Diät- oder Heilpräparaten direkt beigemischt werden.
Sie werden zweckmä#ig einem Getränk oder flüssigen Nahrungsmittel, z. B. Kaffee, Tee, Suppen usw., zugesetzt, oder einfach in Wasser aufgelost, eingenommen.
Wird das Troekenprä. parat in loser Pul verform verpackt und gelagert, so ist es zweckmässig, die Dosen zu evakuieren oder mit einem inerten Gas zu füllen. Die Tabletten und Kapseln sollen mögliehst in luftdichter Paekung gelagert werden.
Process for the production of dry preparations from oils containing physiologically active compounds.
The subject of the invention is a method which opens up the possibility of dietary or therapeutically valuable, physiologically active compounds containing C) oils, such as concentrates which are known as Vitar mine F. Essential fatty acids, liver oil concentrates, oily solutions of fat-soluble vitamins, through formation of an emulsion and subsequent dehydration, are converted into dry, powdery products, which are dehydrated, reversible emulsions that are mixed with water, the oil in question returns to the state of a finely dispersed, bring liquid emulsion.
The method according to the invention for the production of dietetic or pharmaceutical dry preparations from oils containing physiologically active compounds is characterized in that the e 61 in question is converted into an emulsion, expediently of the O1-in-WATasser type, by means of an aqueous solution of a native albumin, resulting in addition compounds of the lipoprotein type. The emulsion obtained is then dewatered by a gentle drying process and converted into a powdery end product, which is capable of
after adding an aqueous liquid, the 61 contained therein can be converted back into the state of a fine aqueous dispersion.
Under the selected conditions, addition compounds of the lipoprotein type are formed between the albumin and the lipoids. Thanks to the formation of such addition compounds, the oil remains fixed as a disperse phase when the emulsion dries. The presence of these bodies is therefore the decisive prerequisite for such an emulsion to be able to be dried at all without the oil leaking out of the bandage.
The fixation of the oil in the disperse state is essential to achieve the reversible emulsion properties of the dry preparation.
These addition properties of albumin can be supplemented by various additives to create optimal effects. The addition of urea can be of particular importance since this compound is able, for example, to form stable, crystallizable adducts with fatty acids.
Furthermore, depending on the type of oil used, it has proven to be expedient if the adductive capacity of albumin was supplemented by the addition of protein hydrolysates, since these substances are also capable of forming lipoprotein-like adducts.
In addition to this primary formation of complex addition compounds, either relatively large amounts of low molecular weight carbohydrates such as sucrose, glucose, fructose, lactose, maltose and lower dextrins or smaller amounts of high molecular weight colloid substances of the carbohydrate or protein type can be used as stabilizers, depending on the desired emulsion properties such as algins and alginates, pectins, carabiners, dextrins, gelatine, etc., as well as combinations of high and low molecular weight carbohydrates, can be used.
Experiments have shown that emulsions produced by the last-mentioned process at a sufficiently high level. If the aqueous phase of certain carbohydrates can be dehydrated relatively easily by gentle drying processes and powdery products are delivered which, by treatment with water, convert the oil back into the state of a fine aqueous dispersion and this while preserving the full original physiological activity of the oil used.
It has also been shown that instead of or combined with certain types of sugar, other carbohydrates, for example dextrins, starches, hemicelluloses, can advantageously be added to the aqueous phase of the emulsion. In the intended high concentration. In particular, glueose and dextrins and, to a certain extent, sucrose act as antioxidants for the oxygen-sensitive components.
Specifically acting antioxidants of natural origin, which can be added, are particularly well suited ascorbic acid and other substances that regulate the redox potential, such as cysteine, glutathione, etc. B.
Lecithin.
Some of the experimentally prepared dry preparations were quite strongly hygroscopic. This disadvantage can be eliminated by adding a relatively large amount of organic colloid substances, such as starch, certain dextrins, hemicelluloses or gelatine, to the aqueous phase and keeping the glucose and lactose content rather low.
The experiments showed that in this way liver oil concentrates, concentrates of essential fatty acids, high-quality seedling brine and oily solutions of the fat-soluble vitamins A, D and E in Troekenprä. can be transferred with the advantages mentioned. There is the option of adding active ingredients such as vitamin C and vitamins of the B complex as well as essential amino acids, certain trace elements or other active ingredients to the aqueous phase of the emulsion and thus transferring them to the dry preparation.
As albumin, for. B. lactalbumin or ovalbumin can be used. It is preferred to use albumin preparations which contain the natural, surface-active accompanying substances and natural salts of the relevant starting material with a dispersing effect. Such a Lactalbu min preparation can, for. B. can be obtained from a milk powder, whey powder or directly from milk.
In the process according to the invention, the type and amount of the additives can be varied as desired within relatively wide limits. Dry preparations with an oil content of up to about 30 / o, calculated from the total weight, can be used. ht, manufacture ..
In the technical implementation of the process according to the invention, the following drying processes for dewatering the emulsion can be used: atomization drying, drum drying, vacuum drying process The drum drying has the advantage of exposing a smaller surface of the material to the action of atmospheric oxygen than the atomization process.
Vacuum roller drying is particularly suitable because it reduces the risk of decomposition and oxidation of the sensitive active ingredients to a minimum and the solubility of the product is as good as possible. Drying in an inert gas atmosphere is also very advantageous. The choice of the drying process depends on the type of material to be dried, the sensitivity of the active ingredient and the requirements of the product.
The method according to the invention is illustrated by the following example:
Example: Concentrate of essential fatty acids (vitamin F) 75 g lactalbumin (a preparation made from whey powder, which contains the surface-active accompanying substances of albumin) 20 g urea 24 g sucrose 150 g glucose 50 g soluble grain starch 80 g ascorbic acid 1 g dist. Water 600 g
1000 g
The Laetalbumin, urea, sucrose, glueose and ascorbic acid were dissolved in one part of the distilled water, and the starch in the other part of the water.
The vitamin F-oil was emulsified in the sugar-containing albumin solution with a vibromixer and the emulsion obtained was homogenized. The hot starch solution was then mixed well with the emulsion heated to the same temperature, an addition compound of the lipoprotein type being formed.
The emulsion was then drained in a vacuum drum dryer. The powdery dry preparation produced a fine aqueous dispersion of the essential fatty acids through treatment with water.
While homogenization of the emulsion is expedient and advantageous for roller drying, this can be omitted when using the spray-drying process, since the atomization brings about a homogenization of the emulsion.
A portion of the emulsion obtained was dehydrated in a thin-skin vacuum dryer at a pressure of 100 to 0.1 mm Hg and a temperature of about 20 to 60.degree. The dry end product is ground into a more or less fine powder depending on its later use. Treated with about 10 times the amount of water, an aqueous dispersion of the oil was obtained, which consisted of droplets of the order of 1 to 2. The water content should not be more than 3 to 4% for the dry preparation to last well.
The dry preparations produced according to the invention can be compressed into dosed capsules, tablets or dragees or, even in powder form, can be added directly to certain nutritional, diet or medicinal preparations.
They are conveniently added to a drink or liquid food, e.g. B. coffee, tea, soups, etc., added, or simply dissolved in water, taken.
Will the Troekenprä. ready packed and stored in loose powder form, it is advisable to evacuate the cans or to fill them with an inert gas. The tablets and capsules should be stored in an airtight packaging as far as possible.
