Description
Verfahren zur Klärung von Fruchtsäften und ähnlichen Flüssigkeiten In der Nahrungsmittelindustrie werden neuerdings in steigendem Maße zur Klärung von Fruchtsäften u. dgl. Enzyme atts Schimmelpilzen verwendet, die die Eigenschaften haben, die Trübstoffe der Keltermoste aufzulösen bzw. in leicht filtrierbarer Form abzuscheiden.Process for clarifying fruit juices and similar liquids In the food industry recently, clarification is increasing by fruit juices and the like enzymes atts molds used which have the properties have to dissolve the cloudy matter in the wine must or in an easily filterable form to be deposited.
Diesen Enzympräparaten haftet oft ein meist unangenehmer Geruch und Geschmack an, der sich durch an sich bekannte Enzymreinigungsmethoden, z. B. wiederholte Fällung der wäßrigen Lösungen der Enzyme mit Alkohol, entfernen läßt. Hierdurch werden jedoch die Enzympräparate derartig verteuert, daß eine wirtschaftliche Verwendung in der Nahrungsmittelindustrie nicht mehr in Frage kommt.These enzyme preparations often have a mostly unpleasant odor and Taste that can be obtained by enzyme purification methods known per se, e.g. B. repeated Precipitation of the aqueous solutions of the enzymes with alcohol, can be removed. Through this however, the enzyme preparations are so expensive that they can be used economically is no longer an option in the food industry.
Es ist bereits bekannt, außer schwefliger Säure, Formaldehyd und sonstigen Stoffen auch Aktivkohle für Desodorisierzwecke z. B. von Flüssigkeiten zu benutzen. Hierbei ist es jedoch erforderlich, nach der Desodorisierung die mit den Geruchsstoffen beladene Kohle durch Filtration von der Flüssigkeit abzutrennen. Abgesehen davon, daß die Ausführung derartiger Verfahren in der Nahrungsmittelindustrie wirtschaftlich kaum tragbar sein dürfte, erleidet die Enzymwirkung dabei meist auch eine mehr oder minder große Schädigung. Es wurde nun gefunden, d aß man den von den Enzympräparaten herrührenden störenden Eigengeruch und -geschmack beseitigen kann, wenn man so verfährt, daß man zur Klärung von Fruchtsäften u. dgl. Enzympräparate aus Schimmelpilzen, zweckmäßig in fein gemahlener Form mit geringen Mengen, z. B. 0,5 bis a %, aktiver Kohle gemischt, verwendet. Es wurde dabei die überraschende Feststellung gemacht, daß die Wirksamkeit dieser Enzympräparate unverändert erhalten bleibt, während das Auftreten eines Beigeschmacks völlig verhindert wird. Bei dem neuen Verfahren wird bereits durch überraschend geringe Mengen von aktiver Kohle eine völlige Geruchs- und Geschmacksfreiheit der Enzympräparate herbeigeführt. Die zur Geruchs-und Geschmacksverbesserung verwendete Aktivkohle verbleibt verfahrensgemäß in dem Präparat.It is already known, besides sulphurous acid, formaldehyde and others Substances also activated carbon for deodorization purposes z. B. to use liquids. In this case, however, it is necessary, after deodorization, to remove the odorous substances to separate charged charcoal from the liquid by filtration. Apart from this, that such processes are economical to carry out in the food industry is unlikely to be acceptable, the enzyme effect usually suffers a greater or lesser degree less severe damage. It has now been found that the enzyme preparations were used can eliminate the unpleasant smell and taste originating from, if one proceeds in this way, that for the clarification of fruit juices and the like enzyme preparations from molds, expediently in finely ground form with small amounts, e.g. B. 0.5 to a%, more active Mixed coal, used. The surprising finding was made that the effectiveness of these enzyme preparations remains unchanged, while the Occurrence of an off-taste is completely prevented. With the new procedure even surprisingly small amounts of active charcoal produce a complete odor and tastelessness of the enzyme preparations brought about. The ones to improve the smell and taste The activated carbon used remains in the preparation according to the method.
Das Verfahren hat sich als besonders brauchbar erwiesen bei schwer zu klärenden Flüssigkeiten, wie z. B. Traubensaft, Apfelsaft, Birnensaft, Erdbeersaft, Bier und Zwiebelsaft. Beispiel 1 looo 1 frisch gepreßter Apfelsaft werden mit 1,5 kg Filtrationsenzym, welches 1 0'o Kohle enthält, versetzt und bei 15° C über Nacht stehengelassen. Am anderen Tage wird der geklärte Saft von den ausgeschiedenen Trübstoffen abgezogen, filtriert und nach einem der bekannten Verfahren haltbar gemacht.The method has been found to be particularly useful for difficult situations liquids to be clarified, such as B. grape juice, apple juice, pear juice, strawberry juice, Beer and onion juice. Example 1 looo 1 freshly squeezed apple juice are 1.5 kg of filtration enzyme, which contains 1 0'o carbon, added and at 15 ° C over night ditched. On the next day the clarified juice is cleared of the excreted turbid matter peeled off, filtered and preserved by one of the known methods.
' Beispiel 2 i oo 1 Erdbeersaft werden mit i oo g Filtrationsenzym, welches 1,5g Kohle enthält, versetzt und i Stunde auf ¢o° C erhitzt. Dann läßt man den Saft auf Raumtemperatur äbkühlen, wobei sich die Trübstoffe am Boden des Gefäßes gut absetzen. Nach insgesamt 5 Stunden wird der geklärte Saft abgezogen, filtriert und in bekannter Weise, z. B. durch Pasteurisieren, haltbar gemacht. Beispiel 3 Bierwürze wird in üblicher Weise sterilisiert und mit einer frischen Kultur von Penicillium glaucum beimpft; die Kultur wird i o Tage bei 25' gehalten. Das gebildete Pilzmycel wird alsdann von der Kulturflüssigkeit abgetrennt und in einem Luftstrom von 30° getrocknet. Das trockene, fein gemahlene Mycel wird dann mit i % aktiver Kohle gemischt. Hierbei verliert das Präparat seinen Eigengeruch völlig und kann nun in bekannter Weise zur Klärung von Fruchtsäften u. dgl. benutzt werden. Beispiel Aus Hefewasser, Malzauszug ;und Agar-Agar . wird in bekannter Weise ein halbfester Nährboden hergestellt und unter sterilen Bedingungen mit einer Kultur des Aspergillus oryzae beimpft. Die beimpfte Masse wird in Petrischalen 8 Tage bei 30° gehalten; dann wird die ganze von Mycel durchsetzte Masse bei niedriger Temperatur getrocknet, ge- mahlen und nach dem Vermischen mit 1,5 0;ö Kohlepulver als Fermentpräparat in der Nahrungsmittelindustrie verwendet.Example 2 100 1 strawberry juice are mixed with 100 g of filtration enzyme, which contains 1.5 g of charcoal, and heated to ¢ 0 ° C. for 1 hour. The juice is then allowed to cool to room temperature, the turbid substances settling well at the bottom of the vessel. After a total of 5 hours, the clarified juice is drawn off, filtered and in a known manner, for. B. by pasteurization, made durable. Example 3 Beer wort is sterilized in the usual way and inoculated with a fresh culture of Penicillium glaucum; the culture is held at 25 'for 10 days. The fungal mycelium formed is then separated from the culture liquid and dried in a stream of air at 30 °. The dry, finely ground mycelium is then mixed with 1% active charcoal. The preparation completely loses its own odor and can now be used in a known manner to clarify fruit juices and the like. Example from yeast water, malt extract; and agar-agar. a semi-solid culture medium is prepared in a known manner and inoculated under sterile conditions with a culture of Aspergillus oryzae. The inoculated mass is kept in Petri dishes for 8 days at 30 °; then the whole penetrated by mycelium mass is dried at a low temperature, grinding charged and, after mixing with 1.5 0; ö carbon powder used as Fermentpräparat in the food industry.
