aus Hefe.from yeast.
Die vorliegende Erfindung betrifft ein Verfahren zur vollkommenen und erschöpfenden Extraction des Zellprotoplasmas der Hefe, indem dasselbe in verdautes Albumin .(eine Mischung von Albumosen und Peptonen) umgewandelt wird, während der Ueberschufs der vorhandenen Kalisalze ausgeschieden wird.The present invention relates to a method for complete and exhaustive Extraction of the yeast cell protoplasm by converting it into digested albumin. (A Mixture of albumoses and peptones) is converted, while the excess of existing potassium salts is excreted.
Das Verfahren besteht im Wesentlichen darin, die vorher durch geeignete Waschungen (vortheilhaft mittels essigsäurehaltigen Wassers) gereinigte Hefe mit einer wässerigen Lösung von Weinsäure zu behandeln, wobei eine bestimmte Concentration und eine bestimmte Temperatur eingehalten wird. Die Menge der Säure und die höchste Grenze der Temperatur, auf welche die Mischung während der Behandlung gebracht wird, ist durch den Versuch festzustellen, so dafs man die möglichst vollständige Umwandlung der Albumine in eine Mischung von Albumosen und Peptonen in dem gewonnenen Extract erreicht und die Notwendigkeit, die angewendete Säure nach der Behandlung zu neutralisiren, vermeidet.The process essentially consists in washing it beforehand by means of suitable washes (advantageous using acetic acid-containing water) to treat yeast purified with an aqueous solution of tartaric acid, whereby a certain Concentration and a certain temperature is maintained. The amount of acid and the highest limit of temperature, to which the mixture is brought during treatment is by trial so that the most complete conversion of the albumins into a mixture of albumoses and peptones is achieved in the extract obtained and the The need to neutralize the acid used after the treatment is avoided.
Zu dem angeführten Zwecke sind bereits verschiedene andere Säuren, namentlich Salzsäure und Milchsäure, verwendet worden, aber diese Säuren zeigen den Uebelstand, in den Extracten grofse Mengen der Kalisalze zurückzulassen. Die Weinsäure hat die Eigenschaft, die Kalisalze in Bitartrate überzuführen, die wenig löslich sind und sich ausscheiden, worauf sie durch Filtration abgeschieden werden können.Various other acids, notably hydrochloric acid, are already used for the stated purpose and lactic acid, but these acids show the disadvantage in the Extracts to leave behind large quantities of the potash salts. The tartaric acid has the property to convert the potassium salts into bitartrates, which are sparingly soluble and precipitate, whereupon they can be separated out by filtration.
Nach dem vorliegenden Verfahren versetzt man 100 Gewichtsfheile trockner Hefe, die vorher durch geeignete Waschungen gereinigt wurde, mit 800 Gewichtstheilen Wasser und 2 (höchstens 4) Theilen Weinsäure. Dann wird die Mischung geschüttelt, um die Bestandtheile in genügende Berührung zu bringen.According to the present process, 100 parts by weight of dry yeast are added was previously cleaned by suitable washes, with 800 parts by weight of water and 2 (at most 4) parts of tartaric acid. Then the mixture is shaken to remove the constituents to bring them into sufficient contact.
0,5 pCt. Weinsäure genügen immer zur Umwandlung der Eiweifsstoffe und zur theilweisen Fällung der Kalisalze, ohne dafs später, eine Neutralisation stattzufinden braucht.0.5 pCt. Tartaric acid is always sufficient for the conversion of the albuminous substances and in part Precipitation of the potassium salts without any subsequent neutralization having to take place.
Die Menge der zuzufügenden Weinsäure wechselt nach dem Gehalte der Hefe an Kalisalzen, der durch Analyse festgestellt ist. Bei den meisten Hefen ist das angestrebte Resultat mit 0,2 pCt. Weinsäure erreicht worden.The amount of tartaric acid to be added varies according to the yeast content Potash salts determined by analysis. For most yeasts, this is the goal Result with 0.2 pCt. Tartaric acid has been achieved.
Die Mischung wird zuerst langsam auf 600C. gebracht, um die Hefe abzutödten und eine Sterilisation zu bewirken. Dann wird die Temperatur auf 45 bis 50 ° C. erniedrigt und hierbei 12 bis 15 Stunden gehalten. Gegen das Ende des Verfahrens steigert man die Temperatur auf 70° C, um von Neuem zu sterilisiren und eventuell die noch nicht in Lösung gebrachten Albumine zu coaguliren.The mixture is first brought slowly to 60 0 C., the yeast mortify and to effect sterilization. Then the temperature is lowered to 45 to 50 ° C. and held for 12 to 15 hours. Towards the end of the process, the temperature is raised to 70 ° C. in order to sterilize again and possibly to coagulate the albumins which have not yet been dissolved.
Nach dem Erkalten filtrirt man und dampft das Filtrat langsam bis zur Syrup- oder Pastenconsistenz ein.After cooling, it is filtered and the filtrate is slowly evaporated to a syrup or paste consistency a.
Die pastenartige Masse wird in 2 1J2 Theilen Wasser gelöst und von Neuem filtrirt. Das erhaltene Filtrat wird bis zur gewünschten Consistenz eingedampft. Die Analyse des Filtrates und der auf dem Filter gebliebenen Rückstände zeigt, dafs ein Drittel der Kalisalze aus dem Hefenextract ausgeschieden worden ist.The paste-like mass is dissolved in 2 1 J 2 parts of water, and filtered again. The filtrate obtained is evaporated to the desired consistency. Analysis of the filtrate and of the residue left on the filter shows that a third of the potassium salts have been eliminated from the yeast extract.
In einem nach dem vorliegenden Verfahren erhaltenen Filtrat wurden nur 3,90 g Kali gefunden, während in dem Ausgangsmaterial 6,24 g vorhanden waren.In a filtrate obtained by the present process, only 3.90 g of potash were found, while there was 6.24 g in the starting material.
Die Analyse der durch die Behandlung mit Weinsäure erhaltenen Paste, die durch Erhitzen auf ioo° C. zur vollkommenen Trockne gebracht war, ergabAnalysis of the paste obtained by treatment with tartaric acid made by heating was brought to 100 ° C. to dryness, resulted

Aufser den angeführten Vortheilen bietet die Anwendung der Weinsäure den besonders für Extracte, die zur Ernährung bestimmt sind, sehr wichtigen Vortheil, Producte zu liefern, die einen bedeutend angenehmeren Geschmack haben als diejenigen, die durch Behandlung mit anderen Säuren erhalten wurden.In addition to the advantages mentioned, the use of tartaric acid offers the especially for Extracts intended for nutrition, very important advantage of supplying products, which have a significantly more pleasant taste than those which have been treated with other acids.
