Description

Verfahren zum Schönen von Trauben, Obst- und Beerenweinen und -mosten Durch die Bekämpfung der Rebschädlinge mit arsenhaltigen Spritzmitteln gelangt Arsen in Most und Wein. Bisher ist eine Entfernung des Arsens bzw. eine Herabsetzung auf gesundheitsunschädliche Mengen nicht erreicht worden. Mit den bisher vorgeschlagenen Methoden ist es nicht möglich, überhauptdenArsengehalt merklichherabzusetzen, den Wein genießbar zu erhalten und eine praktische Durchführung der Entarsenierung auf einfache und billige Weise vorzunehmen.Process for enhancing grapes, fruit and berry wines and musts By combating vine pests with sprays containing arsenic, arsenic is released in must and wine. So far, arsenic has been removed or reduced to Harmless quantities have not been reached. With the previously proposed Methods it is not possible to noticeably reduce the arsenic content at all To keep wine edible and to carry out the arsenic removal on a practical basis easy and cheap way to make.

Es ist bekannt, daß frischgefällte Hydroxyde des Aluminiums, Eisens, Chroms, Cadmiums, Zinks, Mangans, gealtertes Aluminiumhydroxyd und Zirkonoxyhydrat, arsenige Säure und Arsensäure adsorbieren. Alle diese Mittel versagen aber in ihrer Anwendung auf. Wein, Most und ähnliche Getränke, da entweder die Adsorptionskraft zu gering ist, also eine restlose Entfernung des Arsens zu lange dauert, oder aber nicht unerhebliche Mengen der genannten Stoffe in Lösung gehen und damit die genannten Getränke ungenießbar machen.It is known that freshly precipitated hydroxides of aluminum, iron, Chromium, cadmium, zinc, manganese, aged aluminum hydroxide and zirconium oxyhydrate, Adsorb arsenic acid and arsenic acid. But all these means fail in theirs Use on. Wine, cider and similar drinks, as either the adsorption power is too small, i.e. a complete removal of the arsenic takes too long, or else not inconsiderable amounts of the substances mentioned go into solution and thus those mentioned Make drinks inedible.

Es wurde nun gefunden, daß sich das Arsen und neinetwaiger Bleigehalt aus Mosten und Weinen in besonders vorteilhafter Weise dadurch entfernen läßt, daß der Most oder der Wein mit solchen Eisenoxyden behandelt wird, die in der Weise hergestellt worden sind, daß Eisenhydroxyd durch Erhitzen weitgehend entwässert wird, ohne daß das Erhitzung sprodukt seine amorphe Struktur verliert. Als Beispiel für die Behandlung der Eisenhydroxyde sei die eine Stunde lang durchgeführte Erhitzung von Raseneisenerz auf Temperaturen von etwa 35o" C in einem inerten Gasstrom, beispielsweise in einem trockenen Strom von Luft, Stickstoff oder Kohlensäure angeführt. Es genügt, wenn der von dem Arsen zu befreiende Wein oder Most mit den fein verteilten Oxyden versetzt und von Zeit zu Zeit umgerührt wird. Nachdem die Oxyde ihre Adsorptionswirkung ausgeübt haben, lassen sie sich ohne Schwierigkeit nach den üblichen Methoden, beispielsweise durch Filtration, Dekantieren oder Abstechen aus dem Wein oder Most entfernen.It has now been found that the arsenic and any lead content can be removed from musts and wines in a particularly advantageous manner that the must or the wine is treated with such iron oxides, which in the way have been made that iron hydroxide largely dehydrated by heating without the heating product losing its amorphous structure. As an an example for the treatment of the iron hydroxides, let the heating be carried out for one hour of turf iron ore to temperatures of about 35o "C in an inert gas stream, for example headed in a dry stream of air, nitrogen, or carbonic acid. It is sufficient, if the wine or must to be freed from the arsenic with the finely divided oxides and is stirred from time to time. After the oxides have their adsorptive action have exercised, they can be removed without difficulty by the usual methods, for example remove from the wine or must by filtration, decanting or tapping.

Das hier beschriebene Verfahren weist den besonderen Vorteil auf, daß durch Zusatz der genannten Eisenoxyde ausschließlich das Arsen und das Blei aus dem Wein oder Most entfernt wird, während die übrigen, darin enthaltenen Substanzen von dem Eisenoxydzusatz unbeeinflußt bleiben, wogegen andererseits das Adsorptionsmittel in dem Wein oder Most völlig unlöslich ist und sich deshalb quantitativ wieder daraus .entfernen läßt. Beispiel Zu einem arsenhaltigen Wein wurde fein verteiltes aktives Eisenoxyd, hergestellt durch einstündiges Erhitzen von Eisen.hydroxyd bei einer Temperatur von etwa 350"C in einem trockenen Luftstrom, im Verhältnis 2g/1 gegeben. Im Verlauf von 8 Tagen wurde durch mehrfaches Umrühren eine gute Verteilung bewirkt. Nach Verlauf von 8 Tagen wurde der Wein abgestochen und durch !ein Anschwemmfilter filtriert. Bei der Prüfung des so behandelten Weines ergab sich, daß nach einem exakten kolorimetrischen Verfahren nur noch Spuren von Arsen nachzuweisen waren. Der Wein war nach Geschmack und Farbe -unverändert geblieben. Eisenoxyd war nicht in Lösung gegangen.The method described here has the particular advantage of that by adding the iron oxides mentioned, only arsenic and lead are added is removed from the wine or must, while the remaining substances contained therein remain unaffected by the addition of iron oxide, whereas on the other hand the Adsorbent in the wine or must is completely insoluble and therefore quantitative can be removed from it again. Example A wine containing arsenic was mixed with finely divided active iron oxide, produced by heating iron hydroxide for one hour a temperature of about 350 "C in a dry air stream, in the ratio 2g / 1 given. Over the course of 8 days, repeated stirring resulted in good distribution causes. After 8 days, the wine was tapped and passed through a precoat filter filtered. When the wine treated in this way was tested, it was found that after a only traces of arsenic could be detected by exact colorimetric methods. The taste and color of the wine remained unchanged. Iron oxide was not gone into solution.
