Description
Verfahren zur Gewinnung von Roggenstärke In dem Patent 9I5 559 ist eine Verbesserung des Verfahrens zur Verarbeitung von Roggen auf Stärke nach dem Patent 742 638 unter Schutz gestellt, durch das die Stärkeverluste durch enzymatischen Abbau der Stärke im Laufe ihrer Freilegung und Abtrennung dadurch vermieden werden, daß möglichst bald vor der Ab trennung der Stärke, zweckmäßig sogar vor der Auswaschung der Schleimstoffe aus dem Roggengut, die Enzyme, insbesondere die Diastase, abgetötet werden.Process for the production of rye starch In the patent 9I5,559 is an improvement in the process of processing rye for starch after Patent 742 638 placed under protection, by which the starch losses by enzymatic Degradation of the starch in the course of its exposure and separation can thereby be avoided, that as soon as possible before the separation of the starch, expediently even before the washout the mucilage from the rye, the enzymes, especially the diastase, killed will.
Im Patent erg 559 wird als Mittel hierfür eine saure Behandlung des Rohgutes vorgeschlagen, bei der den wäßrigen Behandlungsflüssigkeiten vor, bei oder nach der Extraktion eine Azidität gegeben wird, die genügt, um die Enzyme abzutöten. In the patent erg 559, an acidic treatment of the Proposed raw material in which the aqueous treatment liquids before, with or given an acidity sufficient to kill the enzymes after the extraction.
Es wurde nun gefunden, daß es auch gelingt, die enzymatisch bedingten Stärkeverluste bei einer Ausführung des Stärkegewinnungsverfahrens in alkalischem Medium zu vermeiden und gleichwohl die Stärkeisolierung ohne nennbareVerluste durchzuführen, wenn man die Alkalikonzentration der ersten Auswaschbehandlung so niedrig wählt, daß unerwünschte Beeinflussungen der Stärke, besonders auch lästige Quellungserscheinungen in der auszuwaschenden Schleimstofffraktion durch das Alkali vermieden werden. It has now been found that it is also possible to manage the enzymatically induced Starch losses when the starch production process is carried out in alkaline Avoid medium and at the same time carry out the starch insulation without any noticeable losses, if one chooses the alkali concentration of the first washout treatment so low, that undesirable influences on the strength, especially annoying swelling phenomena can be avoided in the mucilage fraction to be washed out by the alkali.
Es zeigte sich, daß unter solchen Bedingungen die Enzyme, insbesondere die Diastase, zwar nicht abgetötet werden, wohl aber, wie dies aus der Literatur bekannt ist, in ihrer Wirksamkeit so weit herabgesetzt sind, daß ein fühlbarer Stärkeabbau nicht zu befürchten ist, besonders wenn die Arbeitstemperatur bis zur Trennung der Waschlauge von der Stärkemasse niedrig gehalten und die Abtrennung der Stärke von dem Waschwasser beschleunigt wird. It was found that under such conditions the enzymes, in particular the diastasis, although not killed, but as shown in the literature is known in its effectiveness so far are reduced that a noticeable reduction in starch is not to be feared, especially if the working temperature until the washing liquor is separated from the starch mass and kept low and the separation the strength of the wash water is accelerated.
Man hat bei dieser Arbeitsweise den Vorteil, den Reaktionswechsel zu vermeiden, da man nach der Abtrennung der Waschlauge von der leicht alkalisch gebliebenen Stärkemasse diese, falls nötig;. lediglich durch Zusatz von Alkalilauge auf die für ihre Aufarbeitung analog der Reisstärkegewinnung notwendige Alkalinität zu bringen hat. This method of working has the advantage of changing the reaction to avoid, since after the separation of the washing liquor from the slightly alkaline leftover starch mass this, if necessary. simply by adding alkali on the alkalinity necessary for their processing analogous to the extraction of rice starch has to bring.
Allerdings geht bei dieser Arbeitsweise ein geringer Teil des Roggenklebers in Lösung und wird mit der Waschlauge aus der Stärke entfernt, so daß die Kleberausbeute bei der weiteren Verarbeitung der Stärke zurückgeht. Dafür steigt aber der Eiweißgehalt in der Schleimstofifraktion entsprechend an, wodurch diese in ihrem Wert als Nahrungsmittel verbessert wird. However, a small part of the rye glue goes with this method of working in solution and is removed from the starch with the washing liquor, so that the adhesive yield with further processing the starch decreases. But the protein content increases in the mucilage fraction accordingly, which increases their value as food is improved.
