Abstract

Green tea extract is decaffeinated and contains little tannin but has a high L-theanine content.

Description

Gegenstand der vorliegenden Erfindung ist ein coffeinarmer, gerbstoffarmer, theaninangereicherte Grünteeextrakt, Verfahren zu seiner Herstellung sowie seine Verwendung.The present invention relates to a low-caffeine, low-tannin, theanine-enriched green tea extract, process for its preparation and its use.

Normaler wässriger Grünteeextrakt enthält Koffein, Gerbstoffe und L-Theanin.Normal aqueous green tea extract contains caffeine, tannins and L-theanine.

Es ist bekannt, dass L-Theanin entspannende Wirkung besitzt.L-theanine is known to have a relaxing effect.

Die Erfindung hat sich die Aufgabe gestellt, einen Grünteeextrakt zur Verfügung zu stellen, welcher als entspannende Zutat auch zu Getränken oder Getränke­ konzentraten zugegeben werden kann.The object of the invention is to provide a green tea extract to provide which as a relaxing ingredient also to beverages or beverages concentrates can be added.

Diese Aufgabe wird gelöst durch einen Grünteeextrakt, der sowohl entkoffeiniert und gerbstoffarm, aber bezüglich L-Theanin angereichert ist.This task is solved by a green tea extract that is both decaffeinated and low in tannins, but enriched in L-theanine.

Ein derartiger Grünteeextrakt wird erfindungsgemäß hergestellt, indem Grün­ teeblätter, Grünteefannings oder Grünteepulver zunächst entkoffeiniert und dann mit Wasser extrahiert werden, woraufhin der Extrakt mit Polystyrol in Kontakt gebracht und anschließend aufkonzentriert wird.According to the invention, such a green tea extract is produced by green tea leaves, green tea tannins or green tea powder first decaffeinated and then extracted with water, whereupon the extract with polystyrene in Brought into contact and then concentrated.

Vorzugsweise wird der konzentrierte Extrakt anschließend zusammen mit einem Trägerstoff sprühgetrocknet, vakuumbandgetrocknet oder gefriergetrocknet.The concentrated extract is then preferably combined with a Spray dried, vacuum belt dried or freeze dried carrier.

Durch die Entfernung des Koffeins wird die entspannende Wirkung des Grüntee­ extrakts deutlich verstärkt.By removing the caffeine, the relaxing effects of green tea become extract significantly strengthened.

Die Entkoffeinierung erfolgt vorzugsweise mit den üblichen Methoden, wie zum Beispiel mittels überkritischer Kohlensäure oder Ethylacetat. Decaffeination is preferably carried out using the usual methods, such as Example using supercritical carbonic acid or ethyl acetate.  

Die erfindungsgemäße Behandlung des wässrigen Extrakts mit Polystyrol führt überraschenderweise zu einer teilweisen Entfernung der Gerbstoffe, nicht jedoch des L-Theanins. Bei dem erfindungsgemäßen Verfahren verbleiben eine geringe Menge Tee-Polyphenole im Extrakt, welche einerseits den Geschmack der Ge­ tränke verbessern, jedoch andererseits nicht mehr in der Lage sind, sonstige Bestandteile der Getränke und Getränkekonzentrate auszufällen. Durch den Zusatz des erfindungsgemäßen Grünteeextrakts zu Getränken oder Getränke­ konzentraten vermindert sich die Neigung zur Sedimentation.The treatment according to the invention of the aqueous extract with polystyrene leads Surprisingly, partial removal of the tannins, but not of L-theanine. In the process according to the invention, a small number remain Amount of tea polyphenols in the extract, which on the one hand affects the taste of the Ge improve potions, but on the other hand are no longer able to do other things Precipitate components of drinks and beverage concentrates. By the Addition of the green tea extract according to the invention to beverages or beverages the tendency towards sedimentation is reduced.

Zur Herstellung des erfindungsgemäßen Grünteeextrakts werden vorzugsweise Grünteequalitäten eingesetzt, die an sich schon einen höheren L-Theaningehalt besitzen. Der L-Theaningehalt von Grüntee bewegt sich laut Literaturangaben im Bereich von 0,2 bis 2.7%.For the production of the green tea extract according to the invention, preference is given to Green tea qualities used, which in themselves have a higher L-Theaningehalt have. According to the literature, the L-theaning content of green tea is in the Range from 0.2 to 2.7%.

Die Entkoffeinierung mit überkritischem CO2 erfolgt vorzugsweise im Tempera­ turbereich zwischen 30 und 70°C.Decaffeination with supercritical CO 2 is preferably carried out in the temperature range between 30 and 70 ° C.

Die wässrige Extraktion des entkoffeinierten Grüntees mit Wasser kann im Tem­ peraturbereich zwischen 10 und 90°C erfolgen. Der ablaufende Dünnextrakt wird gesammelt und über eine Absorberkolone mit Polystyrolharz geführt. Die ablaufende Menge wird gesammelt und aufkonzentriert.The aqueous extraction of the decaffeinated green tea with water can be temp temperature range between 10 and 90 ° C. The expiring thin extract is collected and passed over an absorber column with polystyrene resin. The running amount is collected and concentrated.
