Description

Verfahren zum Klären von Fruchtsäften, Süßmosten und ähnlichen Erzeugnissen Es sind bereits Verfahren zum Klären von Fruchtsäften, Süßmosten u. dgl. bekanntgeworden, die darin bestehen, daß man die in den rohen Keltersäften enthaltenen Trubstoffe mit trubstoffabbauenden Enzymen von Schimmelpilzen (Filtrationsenzyme) behandelt, die nunmehr filtrierfähig gewordenen Trubstoffe durch Filtration in an sich bekannter Weise abtrennt und die blanken Säfte durch Entkeimungsfiltration, Pasteurisation, oligodyna. mische Entkeimung haltbar macht. An Stelle der Filtration oder des Absitzenlassens hat man sich auch bereits des Zentrifugierens zum Abscheiden der sichtbar gewordenen Trubstoffausscheidungen bedient. Es war weiterhin, bekannt, daß mit dem enzymatischen Trubabbau eine Viscositätsverminderung einhergeht.Process for clarifying fruit juices, sweet musts and similar products Processes for clarifying fruit juices, sweet musts and the like have already become known, which consist in removing the sediment contained in the raw wine juices treated with enzymes from mold that break down turbidity (filtration enzymes), the turbid matter that has now become filterable by filtration in a manner known per se Way and the bare juices by sterilization filtration, pasteurization, oligodyna. mixed disinfection makes it durable. Instead of filtration or settling One has already started centrifuging to separate the visible ones Served sediment excretion. It was further known that with the enzymatic Decomposition of lees is accompanied by a reduction in viscosity.

Es wurde nun gefunden, daß man die Trubstoffe bereits nach sehr kurzer Einwirkungsdauer des Enzympräparats auf das als Schutzkolloid wirkende Pektin durch Zentrifugieren vollständig entfernen kann, und zwar ist dies bereits in einem Stadium möglich, in dem äußerlich noch keine Veränderung des Trübungsgrades wahrnehmbar ist.It has now been found that the sediment can be removed after a very short time Duration of action of the enzyme preparation on the pectin, which acts as a protective colloid Centrifugation can remove it completely, and indeed this is already at one stage possible, in which no change in the degree of opacity is noticeable externally is.

Es hat sich nämlich gezeigt, daß die Viscosität der Kelters,äfte, die durch ihren Pektingehalt bedingt ist, in dem Maße, wie die pektinabbauenden Enzyme zur Wirkung gelangen, bis zu einem gewissen Wert abnimmt. Dieser Wert wird erreicht, noch bevor der Klärungsaufbruch sichtbar geworden ist. Es ist nun in einfacher Weise möglich, diesen Wert mit einem Viscosimeter zu bestimmen. Dieser Zeitpunkt ist dann eingetreten, wenn die Abnahme des Viscositätsgrades nicht mehr schnell stattfindet, sondern praktisch zum Stillstand gekommen ist.It has been shown that the viscosity of the wine presses, juices, which is conditioned by its pectin content to the same extent as the pectin-degrading ones Enzymes get to work, decreases to a certain value. This value will reached before the start of clarification has become visible. It's easier now Way possible to determine this value with a viscometer. This point in time has occurred when the decrease in the viscosity grade is no longer rapid takes place, but has practically come to a standstill.

Die nach dem Verfahren der Erfindung behandelten Fruchtsäfte, Süßmoste u. dgl.liefern ein völlig blankes Zentrifugat, das anschließend sofort durch die Entkeimungsfiltration, Pasteurisation, oligodynamische Entkeimung usw. haltbar gemacht werden kann. Beispiel i Ein frisch gekelterter Apfelsaft wird in an sich bekannter Weise mit 2°/0o eines im Handel befindlichen sog. Filtrationsenzyms bei 20°C behandelt. Während zu Beginn des Versuchs eine Viscosität von 26 Sekunden festgestellt wurde, sinkt dieselbe im Verlauf von 2 Stunden auf einen Wert von z o Sekunden. Bei diesem Wert ist die Viscositätsabnahme praktisch zum Stillstand gekommen. (Der Wasserwert des Viscosimeters beträgt z. B. 9 Sekunden). Man läßt nunmehr den enzymatisierten Saft über einen Separator laufen und schließt unmittelbar daran eine Entkeimung durch Entkeimungsfilter, Pasteurisation usw. an. Beispiel 2 ` Frisch gepreßter Traubensaft wird wie in Beispiel i mit 20/00 Filtrationsenzym bei 20° C behandelt. Die Viscositätsmessung ergibt zu Beginn des Versuches einen Wert von 17 Sekunden. Schon nach i Stunde sinkt dieser Viscositätswert auf 12 Sekunden, wobei wiederum wie in Beispiel i der Wasserwert des Viscosimeters 9 Sekunden beträgt. Mit diesem Wert ist die Viscositätsabnahme praktisch zum Stillstand gekommen. Aus dem äußerlich noch nicht veränderten Traubensaft wird durch anschließendes Zentrifugieren der Trub vollständig abgetrennt und der blanke Saft dann in an sich bekannter Weise haltbar gemacht.The fruit juices, sweet musts and the like treated according to the method of the invention produce a completely clean centrifugate, which can then be immediately preserved by sterilization filtration, pasteurization, oligodynamic sterilization, etc. Example i A freshly pressed apple juice is treated in a manner known per se with 2% of a commercially available so-called filtration enzyme at 20.degree. While a viscosity of 26 seconds was found at the beginning of the experiment, it drops to a value of zo seconds in the course of 2 hours. At this value the decrease in viscosity has practically come to a standstill. (The water value of the viscometer is 9 seconds, for example). The enzymatized juice is now allowed to run through a separator and is immediately followed by sterilization by means of sterilization filters, pasteurization, etc. Example 2 Freshly squeezed grape juice is treated as in example i with 20/00 filtration enzyme at 20 ° C. The viscosity measurement gives a value of 17 seconds at the beginning of the experiment. After just one hour, this viscosity value drops to 12 seconds, again, as in example i, the water value of the viscometer being 9 seconds. With this value, the decrease in viscosity has practically come to a standstill. The trub is completely separated from the grape juice, which has not yet changed externally, by subsequent centrifugation and the bare juice is then preserved in a manner known per se.
