Description

       

  Verfahren zur Erhöhung des     Aromagehaltes    von Genussmitteln.         1:s    ist bekannt,     teinfreien    Tee dadurch       herzustellen,    dass Schwarztee, wie er als     Fer-          tigprodukt    von der Plantage geliefert wird,  (las     licisst    nach der Fermentation und     Röstung     der     grünen    Teeblätter, zuerst mit     Wasser        der-          waLien    stark benetzt wird,

   dass sieh die Zellen  auf ein     llaxiinuin        vero-rössern.    Diese     Zellquel-          lung    ist deshalb     notwendig,    weil bei der     nach-          folgenden    Behandlung der Teeblätter mit       einem    organischen Lösungsmittel dieses letz  tere     (las    Blatt nicht vollständig zu durchdrin  gen und das     Tein    herauszulösen     vermöchte.     



  Bei der beschriebenen     Durehfeuclitung    mit  Wasser tritt     nun    äusserst viel Teearoma in  Freiheit und wird an die     Atmo-ipliäre        abgege-          l)i@n.    lies ist eine     natürliehe        Erseheinttng    und  gilt     praktiseh    für alle     aromahaltigen    Natur  stoffe. Dieser     Aromaaustritt    stellt bereits den       ersten        erliebliehen    Verlust dar.  



  Nach der     Quellung    wird das     Tein,    wie be  reits angedeutet, durch Extraktion mit einem       organisehen        Lösungsmittel    dem Teeblatt ent  zogen. Selbst bei sorgfältigster     Auswahl    des       Lösungsmittels    vermag dasselbe ebenfalls  etwas     Aroniastoffe    nebst dem     Tein    zu     extra-          1iieren,    wodurch ein weiterer,

   allerdings gerin  gerer     Aromaverlust        entsteht.        Schliesslich        muss     nach erfolgter Extraktion das anhaftende  Lösungsmittel und das     Anfettehttingswasser     durch Wärme entfernt werden, was     verständ-          lielierweise    einen erneuten     Aromaverlast        her-          orruft.     



       T:s    versteht sieh von selbst, dass nach einer       derartigen        Behandlun-    die     teinfreien    Teeblät-         ter    einen wesentlichen Anteil ihres     ursprÜng-          lichen    Aromas verloren haben und einen faden  Geruch aufweisen.  



       Caegenstand    der vorliegenden Erfindung  ist nun ein Verfahren zur Erhöhung des       Aromagehaltes    von     Genussmitteln,    welches da  durch     gekennzeichnet    ist, dass eine     aromage-          .=,ä.ttigte    Atmosphäre, welche bei der Behand  lung eines     aromahaltigen        Oenussmittels    mittels  Wasser erhalten wurde, auf das zu behan  delnde Genussmittel einwirken gelassen wird.  



  Die Erfindung geht von der Tatsache aus,  dass     aromahaltige    Naturprodukte ihr Aroma  teilweise abgeben, sobald ihnen Wasser und  ähnliche     Flüssigkeiten    oder wasserlösliche       Substanzen    zugesetzt werden, und dass die  natürlich freigewordenen oder     absichtlieli     getriebenen     Aromastoffe    durch     aromaar        me     <B>,</B>     tius     Produkte im allgemeinen. leicht     adsorbiert          werden.     



  Die zur Durchführung des erfindungsge  mässen Verfahrens benötigte     aromagesättigte     Atmosphäre kann dadurch erhalten werden,  dass     Genussmittel,    welche     Aromastoffe    abzu  geben vermögen und     schädli:

  ehe    und/oder an  dere unerwünschte Bestandteile aufweisen, zu  erst zwecks     Quellung    der Zelle mit Wasser       durehfeuchtet,    hierauf gegebenenfalls zur Ex  traktion der schädlichen Bestandteile mit  einem organischen Lösungsmittel behandelt,       das    anhaftende Wasser und gegebenenfalls  Lösungsmittel entfernt und die durch diese  Behandlung entstandene     aromagesättigte         Atmosphäre auf eine Charge eines     aroma-          armen        Genussmittels    einwirken gelassen wird.  



  Durch das Einwirkenlassen von     aroma-          gesättigter    Atmosphäre auf ein     aromaarmes     Genussmittel wird, auf Grund der     Adsorptions-          fähigkeit    des gegebenenfalls vorbehandelten       Genussmittels,    dieses das Aroma     adsorbieren,     worauf ein Genussmittel verbesserter Qualität  entsteht.  



  Das Auffangen der mit     Aromastoffen    ge  sättigten Atmosphäre kann in beliebiger  Weise erfolgen. So kann man beispielsweise  die     aromagesättigte    Atmosphäre über dem  Behandlungsgefäss absaugen und langsam in  oder über eine Charge von     aromaarmem        Ge-          nussmittel    leiten. Eine andere geeignete Me  thode besteht beispielsweise darin, dass das mit.       Aromastoffen    zu behandelnde     aromaarme        Ge-          nussmittel    unmittelbar über einem ein     aroma-          reiches    Genussmittel enthaltenden Gefäss ge  lagert wird.

    



  Das Verfahren gemäss vorliegender Erfin  dung eignet sieh insbesondere für die     Behand-          hing    von Teeblättern, welchen vorher das     Tein     entzogen worden ist, wobei ein     teinfreier    Tee  erhalten werden kann, der qualitativ dem bis  her bekannten     teinfreien    Tee überlegen ist.    Selbstverständlich lässt sich das neue Verfah  ren auch mit andern Genussmitteln, z. B. Kaf  fee usw., durchführen.  



  Ferner kann das Verfahren gemäss vorlie  gender Erfindung dazu Verwendung finden,  um einem beliebigen     aromaarmen        Genussmit-          tel,    z. B. Kaffee oder Tee minderwertiger  Qualität,     zusätzliehen        Aromageruch    zu verlei  hen, wobei ein Genussmittel besserer Qualität       entsteht.  



  Process for increasing the aroma content of luxury foods. 1: s is known to produce tein-free tea by first wetting black tea, as it is delivered as a finished product from the plantation (las licisst, after fermentation and roasting of the green tea leaves, with water from the plant,

   that you see the cells on a llaxiinuin. This cell swelling is necessary because when the tea leaves are subsequently treated with an organic solvent, this latter (the leaf cannot completely penetrate and the complexion can be dissolved out.



  With the described flow of moisture with water, an extremely large amount of tea aroma is released and is released to the atmosphere. lies is a natural selection and applies in practice to all aromatic natural substances. This escape of aroma is already the first loss suffered.



  After swelling, the tein is, as already indicated, removed from the tea leaf by extraction with an organic solvent. Even with the most careful selection of the solvent, it is also able to extract some aronia substances along with the complexion, whereby another,

   however, there is less loss of flavor. Finally, after the extraction has taken place, the adhering solvent and the fatty water must be removed by means of heat, which, understandably, causes a renewed aroma overload.



       T: s goes without saying that after such a treatment the tein-free tea leaves have lost a substantial part of their original aroma and have a bland odor.



       The subject of the present invention is a method for increasing the aroma content of luxury foods, which is characterized in that an aroma-. =, Ä.aturated atmosphere, which was obtained in the treatment of an aroma-containing nutritious agent by means of water, is to be treated delusive luxury food is allowed to act.



  The invention is based on the fact that aroma-containing natural products partially give off their aroma as soon as water and similar liquids or water-soluble substances are added to them, and that the aroma substances released naturally or intentionally driven by aromaar me <B>, </B> tius products in general. are easily adsorbed.



  The aroma-saturated atmosphere required to carry out the process according to the invention can be obtained by the fact that stimulants which are able to give off aromas and which are harmful:

  before and / or other undesirable constituents have, first of all, dehumidified with water to swell the cell, then optionally treated with an organic solvent to extract the harmful constituents, the adhering water and optionally solvent removed and the aroma-saturated atmosphere created by this treatment on a batch of a semi-aromatic luxury food is allowed to act.



  By allowing an aroma-saturated atmosphere to act on a low-aroma luxury product, due to the adsorption capacity of the possibly pretreated luxury product, it will adsorb the aroma, resulting in a luxury product of improved quality.



  The atmosphere saturated with aromatic substances can be collected in any way. For example, the aroma-saturated atmosphere above the treatment vessel can be sucked off and slowly fed into or over a batch of low-aroma luxury items. Another suitable method is, for example, that with. Flavorings to be treated low-aroma luxury items is stored directly over a vessel containing a high-flavor item.

    



  The method according to the present invention is particularly suitable for the treatment of tea leaves from which the tein has previously been removed, whereby a tein-free tea can be obtained which is qualitatively superior to the tein-free tea known up to now. Of course, the new method can also be used with other luxury foods, e.g. B. Coffee, etc., perform.



  Furthermore, the method according to the present invention can be used to produce any low-aroma luxury food such. B. coffee or tea of inferior quality, hen additional aroma smell to lend, resulting in a luxury food of better quality.
