Description
Verfahren zur Haltbarmachung von alkoholfreiem Fruchtsaft. Seit langem werden Fruchtsäfte, von .der Fruchtpresse weg, in Absatz- bezw. Klär bottiche .gebracht, damit sich die Trub- und Schleimstoffe vor der weiteren @Sa.ftbehand- lung möglichst weitgehend ausscheiden kön nen. Der Klärvorgang wird hierbei meistens durch Zusatz organischer und anorganischer Fällungs.mittel beschleunigt.
Der ,geklärte Saft wird dann zum Beispiel zwecks Lage rung auf längere Zeit einer scharfen Fil tration mit anschliessender Entkeimung unter zogen, und der blanke Saft dann mit Koh lensäure gesättigt, und unter zirka 7 bis 8 Atü. Drucl" ,gesetzt.. Bei einem andern Ver fahren wird der blanke Saft mit einer Tem peratur von zirka 70 Grad Celsius in Tanks gefüllt. In diesen Tanks kann der Saft lang sam abkühlen. Er bleibt darnach, bei An wendung geeigneter Vorsichtsmassregeln steril.
Bei diesem Verfahren ist-; jedoch das Auf treten des sogenannten Kochgeschmackes un- vermeialich.
Die vorliegende Erfindung betrifft ein Verfahren zur Haltbarmachung von alkohol- freiem Fruchtsaft, welches dadurch .gekenn zeichnet ist,-dass ein die Trub- und Schleim stoffe enthaltender Fruchtsaft mit einem Mittel behandelt wird, durch welches die im Saft vorhandenen Bakterien und Hefen abge tötet werden. Es .kann so ein Fruchtsaft mit grosser Haltbarkeit gewonnen werden, wel cher .die Pektinstoffe und die Fruchtfleisch partikel enthält und das Aroma und den Duft der gepressten Frucht aufweist. Durch die Beibehaltung der .genannten Stoffe be sitzt -der Saft einen grösseren Nährwert.
Wird die Abtötung der Bakterien und Hefen durch Momenterhitzen in der ver schlossenen Flasche und rasches Abkühlen derselben vorgenommen, so kann ein Auf treten von Kochgeschmack vermieden werden. Um eine Entmischung des von Natur aus trüben Saftes zu vermeiden, ist es zweck mässig denselben direkt von der Presse auf Flaschen abzufüllen.
<I>Beispiel 1:</I> Der von der Presse kommende, natur trübe Fruchtsaft wird direkt, ohne eine Ent- mischung eintreten zu lassen, auf kleine Be hälter, zum Beispiel Flaschen gefüllt. Die dicht verschlossenen Behälter, werden schnell auf 70 Grad gebracht, um durch Plasmolyse die Bakterien und Hefekulturen abzutöten, und nach fünf Minuten, schnell bis auf Brun- nenwassertemperatur (zirka 10 Grad Celsius) heruntergekühlt.
<I>Beispiel 2:</I> Der Saft wird wie bei Beispiel 1 auf den Behälter, zum Beispiel Flasche gefüllt, und unter Zusatz -des nach der geltenden Lebens- mittelverordnung für Süssmost erlaubten Konservierungsmittels die Plasmolyse der Bakterien und Hefekulturen herbeigeführt.
Process for the preservation of non-alcoholic fruit juice. For a long time, fruit juices, away from the fruit press, in sales or Clarifying vats have been brought in so that the sediment and mucilage can be eliminated as far as possible before further treatment. The clarification process is usually accelerated by adding organic and inorganic precipitation agents.
The clarified juice is then subjected to a sharp filtration with subsequent sterilization for the purpose of storage for a longer period of time, and the bare juice is then saturated with carbonic acid, and under about 7 to 8 atmospheres. In another process, the bare juice is filled into tanks at a temperature of around 70 degrees Celsius. The juice can slowly cool down in these tanks. After this, if appropriate precautionary measures are applied, it remains sterile.
In this procedure is-; however, the appearance of the so-called cooking taste is inevitable.
The present invention relates to a method for preserving alcohol-free fruit juice, which is characterized by .gekenn, -that a fruit juice containing the cloudy and mucous substances is treated with an agent by which the bacteria and yeasts present in the juice are killed . A fruit juice with a long shelf life can thus be obtained, which contains the pectin substances and the pulp particles and has the aroma and fragrance of the pressed fruit. By retaining the substances mentioned, the juice has a greater nutritional value.
If the bacteria and yeasts are killed by instantaneous heating in the closed bottle and rapid cooling of the same, a cooking taste can be avoided. In order to avoid segregation of the naturally cloudy juice, it is advisable to bottle it directly from the press.
<I> Example 1: </I> The naturally cloudy fruit juice coming from the press is poured directly onto small containers, for example bottles, without allowing any segregation to occur. The tightly closed containers are quickly brought to 70 degrees in order to kill the bacteria and yeast cultures by plasmolysis, and after five minutes they are quickly cooled down to well water temperature (approx. 10 degrees Celsius).
<I> Example 2: </I> The juice is filled onto the container, for example a bottle, as in Example 1, and the plasmolysis of the bacteria and yeast cultures is brought about with the addition of the preservative permitted for sweet must according to the applicable food regulations.
