Description

Verfahren zur Herstellung eines vitaminreichen Nahrungsmittels aus Hefe Bevor Hefe als Nahrungsmittel verwendet werden kann, muß eine 'Entfernung verschiedener Verunreinigungen, insbesondere der den Geschmack und dieVerträglichkeitbeeinträchtigenden Fettsubstanzen, herbeigeführt werden. Dieser Forderung ist nicht leicht nachzukommen, da die hierfür in Frage kommenden Mittel im allgemeinen auch eine Herauslösung wertvoller Bestandteile, z. B. -der wasserlöslichen B-Vitamine, aus der Hefe bewirken. Dies tritt, abgesehen natürlich von der Behandlung mit Wasser, beispielsweise auch dann ein, wenn man die Hefe ohne besondere Vorsichtsmaßregeln mit Alkoholen zwecks Entfernung der Fettsubstanzen extrahiert, da die einzelnen B-Vitamine bekanntlich in ihnen löslich sind. Naheliegend ist- es, mit Wasser nicht mischbare Lösungsmittel, wie Benzol, Töluol, Chlorkohlenwasserstoffe, Äther usw., hierfür zu versuchen. Doch hat sich gezeigt, daß auf diese Weise zwar die Reinigung und Entfettung gelingt, jedoch die Hefe kleine :Mengen dieser Extraktionsmittel hartnäckig zurückhält, so daß jetzt der Geschmack der sich ergebenden Produkte nach dieser Richtung stark beeinträchtigt wird.Process for making a food rich in vitamins Yeast Before yeast can be used as food, a 'removal of various Impurities, especially those which impair the taste and the tolerability Fatty substances. This demand is not easy to meet, since the means in question are generally also more valuable to detach them Components, e.g. B. -the water-soluble B vitamins from yeast. this occurs, apart of course from the treatment with water, for example also then one, if you take the yeast without special precautions with alcohols for the purpose of removal The fatty substances are extracted as the individual B vitamins are known to be in them are soluble. Obviously, solvents that are not miscible with water, such as Benzene, töluene, chlorinated hydrocarbons, ethers, etc. to try for this. Indeed it has been shown that cleaning and degreasing succeed in this way, However, the yeast stubbornly holds back small amounts of these extractants, so that now the taste of the resulting products is strong in this direction is affected.

Der vorliegenden Erfindung liegt nun die Erkenntnis zugrunde, daß es von entscheidender Wichtigkeit für die Erhaltung des Vitamingehaltes ist, eine Hefe als Ausgangsmaterial zu verwenden, welche sorgfältig vor plasmolytischen und/oder autolytischen Vorgängen bewahrt worden ist. Es wurde nämlich gefunden, daß bei derartigen Prozessen nebenher ein Zerfall des Wasser- und alkoholunlöslichen Komplexes, in welcher Form die Vitamine in der nach dieser Richtung hin unversehrten Hefe vorliegen, in ihre einzelnen löslicher< Komponenten eintritt. Demgemäß besteht das vorliegende Verfahren darin, daß man frische Hefe sofort nach ihrem Anfall weitgehend von Feuchtigkeit befreit und unter Hintanhaltung plasmolytischer undjoder autolyrischer Vorgänge mittels konzentrierter niederer aliphatischer Alkohole; vorzugsweise Methanol, extrahiert. Hierbei -finden sich in dem alkoholischen J-xtrakt sämtliche unerwünschten Bestandteile der Hefe, während ihr Vitamingehalt erhalten bleibt. Daß sich dieser Effekt auf einem solch einfachen Wege erzielen läßt: muß als außerordentlich überraschend he= zeichnet werden, ist doch z. B. das wichtigste Hefevitamin, das Aneurin, an sich alkohollöslich.The present invention is based on the knowledge that it is of vital importance for the maintenance of the vitamin content, one Yeast to use as a starting material, which carefully before plasmolytic and / or autolytic processes has been preserved. It has been found that in such Processes incidentally a disintegration of the water- and alcohol-insoluble complex, in what form the vitamins are in the yeast that is undamaged in this direction, enters into its individual more soluble components. Accordingly, there is the present The process consists in keeping fresh yeast largely of moisture immediately after it has accumulated freed and restrained from plasmolytic and / or autolytic processes by means of concentrated lower aliphatic alcohols; preferably methanol, extracted. All undesirable constituents are found in the alcoholic J-extract the yeast while maintaining its vitamin content. That this effect is on such a simple way: must be extraordinarily surprising he = be drawn, is z. B. the most important yeast vitamin, the aneurine, in itself alcohol soluble.

Sämtliche schon bekannten Verfahren, die sich mit der Behandlung von Hefe mit Alkoholen befassen, lassen die obengenannten Bedingungen außer acht, indem bei ihnen entweder verdünnter Alkohol zur Verwendung gelangt oder konzentrierterer auf nasse Hefe zur Einwirkung gebracht wird. Demgemäß zeigen die nach ihnen hergestellten Präparate einen weitgehenden Mindergehalt an Vitaminen gegenüber der als Ausgangsmaterial verwendeten Hefe, während nach dem Verfahren der vorliegenden Erfindung Erzeugnisse erhalten «erden, die, frei von geschmackswidrigen und unverträglichen Ballaststoffen, einen überraschend hohen Vitamingehalt besitzen. Beispiele I. 5 kg aus Sulfitablauge gewonnene und sogleich sorgfältig getrocknete Hefe werden in einem Extrakteur nach Art des Soxhlet-Apparates bei d.5° 3 Stunden lang mit Methanol extrahiert. Der Rückstand wird abgeschleudert und bei 35° im Vakuum getrocknet, wobei .f,1 kg trockene Hefe, in welcher sich dieselbe Menge Vitamine wie vor der Extraktion vorfindet, erhalten werden. 2. 5 kg frische und trockene Zellstoffhefe werden 2 Stunden lang bei 5o° mit Äthylalkohol in einem Soxhlet-Apparat extrahiert. Nach dem Abschleudern erhält man 4,05 kg gereinigte und entfettete Hefe, deren Vitamingehalt der gleiche geblieben ist.All already known methods that deal with the treatment of Yeast deal with alcohols, disregard the above conditions by adding they either use diluted alcohol or more concentrated alcohol acted on wet yeast. Accordingly, show those made according to them Preparations have a substantial deficiency in vitamins compared to the raw material used yeast while producing products according to the method of the present invention receive «earths that, free from unflavored and incompatible fiber, have a surprisingly high vitamin content. Examples I. 5 kg from sulphite waste liquor Yeast obtained and carefully dried at the same time are processed in an extractor Type of Soxhlet apparatus extracted with methanol at d.5 ° for 3 hours. The residue is spun off and dried at 35 ° in a vacuum, where .f, 1 kg of dry yeast, which contains the same amount of vitamins as before the extraction will. 2. 5 kg of fresh and dry cellulose yeast are kept at 5o ° for 2 hours extracted with ethyl alcohol in a Soxhlet apparatus. Receives after being thrown off 4.05 kg of purified and defatted yeast, the vitamin content of which remained the same is.

3. 5 kg frische und trockene Holzzuckerhefe werden 2 Stunden lang mit 20 1 Metlianol geschüttelt. Man saugt ab, worauf der Rückstand nochmals mit 2o 1 Methanol 2 Stunden lang geschüttelt wird. Die scharf abgesaugte feste Substanz wird im Vakuum bei 35° getrocknet, wobei man .1,3 kg gereinigte Hefe erhält, welche bezüglich ihres Vitamingehaltes unverändert geblieben ist.3. 5 kg of fresh and dry wood sugar yeast are used for 2 hours shaken with 20 1 Metlianol. One sucks off, whereupon the residue is again with 2o 1 methanol is shaken for 2 hours. The sharply sucked solid substance is dried in vacuo at 35 °, giving .1.3 kg of purified yeast, which has remained unchanged in terms of its vitamin content.
