Description
KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Es ist bekannt, daß man aus stärkehaltigen Früchten, Knollen u. dgl. durch Ausziehen mit Wasser ein Enzym gewinnen kann, welches eine geringe Kraft, Stärke zu verflüssigen, besitzt, dagegen stark verzuckernd auf verflüssigte Stärke wirkt. Durch Zusatz von Alkohol wird das. Enzym aus dem bräunlich oder gelblich gefärbten wässerigen Auszuge gefällt und stellt sich nach dem VerjagenIt is known that starchy fruits, tubers and the like can be extracted by pulling them out can win an enzyme with water, which has little power to liquefy starch, possesses, on the other hand, has a strong saccharifying effect on liquefied starch. By adding Alcohol becomes the enzyme from the brownish or yellowish colored aqueous extracts pleases and turns after being chased away
ίο des Fällungsmittels als ein weißliches Pulver dar.ίο the precipitant as a whitish powder represent.
Sowohl der Extrakt wie das aus ihm iso-Both the extract and the iso-
• lierte Enzym verlieren bei längerer Aufbewahrung das Verzuckerungsvermögen durch die Einwirkung eines Bestandteiles des Extraktes, der ebenfalls durch Alkohol fällbar ist.• Lined enzymes lose if they are stored for a long time the saccharification capacity through the action of a constituent of the extract, which can also be precipitated by alcohol.
Es wurde gefunden, daß diese schädliche Beimengung durch Behandlung des Extraktes mit Säure ausgefällt werden kann. Diese reinigende Behandlung kann entweder auf dem Wege der sauren Gärung oder durch Versetzen mit einer verdünnten Säure, ζ. Β. Milchsäure, erfolgen.This has been found to be harmful Admixture can be precipitated by treating the extract with acid. These Cleansing treatment can either be by acid fermentation or by adding a dilute acid, ζ. Β. Lactic acid.
Der durch Ausziehen VOn11 grob gemahlenem Getreide (Gerste, Mais, Weizen, Reis), Knollen,· Getreideabfällen, Kleie, Mittelmehlen u. dgl. mit Wasser bei gewöhnlicher oder wenig höherer Temperatur erhaltene, je nach dem Ausgangsmaterial bräunlich bis gelblich gefärbte Extrakt wird 30 bis 50 Stunden (am zweckmäßigsten etwa 48 Stunden) lang in einem auf 26 bis 330 C. gehaltenen Räume stehen gelassen. Es bildet sich dabei ein weißlicher Niederschlag. Die gleiche Wirkung wird erzielt, wenn man den Extrakt unmittelbar mit einer verdünnten Säure, z. B. Milchsäure, versetzt. Man trennt die Flüssigkeit vom Niederschlag, und engt sie entweder zur Sirupsdicke ein oder fällt aus ihr das Enzym durch Zusatz von Alkohol.The coarse by drawing 11 ground cereal (barley, maize, wheat, rice), tubers, · cereal waste, bran, means flours u. Like. With water at ordinary or only slightly elevated temperature resulting brownish to yellowish depending on the starting material extract is 30 to 50 hours (most expediently about 48 hours) left to stand in a room kept at 26 to 33 ° C. A whitish precipitate forms. The same effect is achieved if the extract is immediately treated with a dilute acid, e.g. B. lactic acid added. The liquid is separated from the precipitate and either concentrated to the syrup thickness or the enzyme is precipitated from it by adding alcohol.
In gleicher Weise wie mit dem rohen Extrakt kann man auch mit dem aus ihm durch Alkohol gefällten Enzym verfahren, indem man es in wässeriger Lösung in der beschriebenen Weise behandelt.In the same way as with the raw extract, you can also use the extract from it Alcohol-precipitated enzyme proceed by putting it in aqueous solution in the described manner Treated wisely.
