  Verfahren zur Darstellung einer neuen     Jod-Eiweissverbindung.            setzung    des Eiweisses durch gebildete     Jod-          wasserstoffsäure    zu vermeiden, können  zweckmässig säurebindende Mittel, wie Na  triumbikarbonat,     Natriumacetat        etc.,    zugesetzt  werden. Sobald die     Jodierung    fertig ist,  trennt man die Hefe von der Flüssigkeit  durch Zentrifugieren oder Filtrieren und  wäscht den Rückstand mehrmals mit kaltem  Wasser, bis das Waschwasser praktisch keine       Jodreaktion    mehr zeigt. Der Rückstand wird  getrocknet und stellt ein bräunliches Pulver  dar, das bis zu 4 bis 5 % Jod enthält.  



  Die Behandlung mit Jod ist auch in  alkoholischer Suspension oder in getrock  netem Zustande durch Zusammenreiben von  getrockneter Hefe mit gepulvertem Jod mög  lich, wobei dann etwa im Überschuss ange  wandtes Jod durch Behandlung mit schwef  liger Säure entfernt werden kann.    Bierhefe wurde bekanntlich schon früh  als fäulniswidriges Mittel und Antiseptikum  bei Furunkulose und Ekzemen aller Art  benützt. Es wurde nun gefunden, dass durch       Jodieren    von Hefeeiweiss ein Gemisch von  Verbindungen entsteht, welches Bierhefe  gegenüber durch eine bedeutende Verstär  kung der antiseptischen Wirkung charak  terisiert ist. Jodierte Hefe eignet sich in  folge ihres guten Geschmackes auch aus  gezeichnet zur innerlichen Verabreichung  und kann den meisten Nahrungsmitteln bei  gegeben werden.  



  Die Darstellung von jodierter Hefe ge  schieht durch direkte Einwirkung von     jo-          dierenden    Mitteln, zum Beispiel Jod auf  Hefeeiweiss. Unter Hefeeiweiss verstehen  wir auch rohe oder gereinigte Hefe.  



  <I>Beispiel</I>  20 kg     entbitterte    getrocknete Bierhefe  werden mit 50 Liter Wasser 3 bis 7 0 Stun  den     aufquellen    gelassen. 2,4 kg     Jodnatrium     und 0,53 kg     jodsaures    Natron werden in  15 Liter Wasser gelöst; das Gemisch wird  zu dem auf 40 bis 50   erwärmten Hefebrei  langsam zufliessen gelassen. Die Temperatur  wird bis auf 80   gesteigert. Um eine Zer-



  Process for the preparation of a new iodine-protein compound. Acid-binding agents, such as sodium bicarbonate, sodium acetate, etc., can be added to avoid the formation of protein through hydriodic acid. As soon as the iodination is finished, the yeast is separated from the liquid by centrifugation or filtration and the residue is washed several times with cold water until the wash water shows practically no iodine reaction. The residue is dried and is a brownish powder that contains up to 4 to 5% iodine.



  Treatment with iodine is also possible in alcoholic suspension or in a getrock netem state by rubbing together dried yeast with powdered iodine, in which case iodine applied in excess can be removed by treatment with sulphurous acid. Brewer's yeast was known to be used early on as an anti-putrefactive agent and antiseptic for furunculosis and eczema of all kinds. It has now been found that the iodination of yeast protein creates a mixture of compounds which brewer's yeast is characterized by a significant reinforcement of the antiseptic effect. Due to its good taste, iodized yeast is also ideal for internal administration and can be added to most foods.



  Iodized yeast is represented by the direct action of yeasting agents, for example iodine on yeast protein. By yeast protein we also mean raw or purified yeast.



  <I> Example </I> 20 kg of debittered, dried brewer's yeast are left to swell with 50 liters of water for 3 to 7 0 hours. 2.4 kg of sodium iodine and 0.53 kg of sodium iodate are dissolved in 15 liters of water; the mixture is slowly poured into the yeast pulp heated to 40-50. The temperature is increased to 80. In order to
