Description

Im Gärungsgewerbe finden zur Zerstörung unliebsamer Schäume sog. Gärfette Anwendung, die aus Fetten, Ölen oder auch, aus Gemischen solcher mit an sich unwirksamen Mineralölen u. dgl. bestehen. In den heutigen Zeiten, da einerseits sehr große Mengen zuckerhaltiger Lösungen, wie sie die Sulfitablauge des Hiolzaufschluisses und die HoIzzuickerlöisungen darstellen, zur Verarbeitung auf Hefe gelangen, anderseits Fette und Öle zur Schaumverhütung nicht zur Verfügung stehen, ist die Schaffung fettfreier Austauschstoffe für die sog. Gärfette von besonderer Wichtigkeit.In the fermentation industry, so-called fermentation fats are used to destroy unpleasant foams. those made from fats, oils or also from mixtures of those with ineffective ones Mineral oils and the like. In today's times, on the one hand, there are very large quantities solutions containing sugar, such as the sulphite waste liquor of the Hiolzaufschluisses and the wood sugar solutions represent, get for processing on yeast, on the other hand fats and oils are not available for foam prevention, is the creation of fat-free substitutes of particular importance for the so-called fermentation fats.

Es wurde gefunden, daß Gemische von langkettigen ParaffirikoJhlenwasserstoffen mit der Siedegrenze vom 200 bis 360° mit den durch Sulfbchlorierung und nachfolgende Verseifung gewonnenen Sulfonaten von Paraffinkohlenwasserstoffen gleicher Art sehr gute, fettfreie Entschäumungsmittel für die Hefeindustrie darstellen. Ihre Wirkung ist in vielen Fällen siogatr noch derjenigen der bekannten Handelsgärfette überlegen. Eine Beeinträchtigung des Wachstums der Hefezellen ist nicht beobachtet worden. Während das neue Mittel bei der Vergärung auf Hefe von Sulfitablaugen und Holzzuckerlösungen mit bestem Erfolg arbeitet und selbst starke Schäume in kurzer Zeit zerstört, besitzt es auf Melassewürzen nur eine geringe Wirkung.It has been found that mixtures of long-chain paraffin hydrocarbons with the boiling limit from 200 to 360 ° with the by sulfochlorination and subsequent saponification obtained sulfonates of paraffinic hydrocarbons of the same kind very good, represent fat-free defoaming agents for the yeast industry. Your effect is in in many cases it is still that of the known Superior fermentation fats. No impairment of the growth of the yeast cells has been observed. While that using new means for fermentation on yeast of sulphite waste liquors and wood sugar solutions works best and destroys even strong foams in a short time, it owns Molasses spices have little effect.

Beispielexample

50 Teile eines Gemisches langkettiger Paraffinkohlenwassersitoffe mit der Siedegrenze von etwa 200 bis 3600 werden mit 45 Teilen eines durch Sulfochlorierung und nachfolgende Verseifung eines, gleichen Paraffingemisches erhaltenen Sulfonats und 5 Teilen Wasser zu einer Paste verrührt. 1 Teil dieser Paste wird nun mit 3 Teilen Wasser zu einer Stammemulsiion gelöst, von der je nach Bedarf der betreffenden .Gärflüssigkeit geringe Mengen zugesetzt werden. Zur Erzeugung von50 parts of a mixture of long-chain paraffin hydrocarbons with a boiling limit of about 200 to 360 0 are mixed with 45 parts of a sulfonate obtained by sulfochlorination and subsequent saponification of an identical paraffin mixture and 5 parts of water to form a paste. 1 part of this paste is then dissolved with 3 parts of water to form a stock emulsion, small amounts of which are added to the fermentation liquid in question as required.
