Description

Verfahren zur Herstellung eines Nahrungsmittels, Verwendung von Fett zur Einbettung von Selen und ein Nahrungsmittel Method for producing a food, use of fat for embedding selenium and a food
Die Erfindung betrifft ein Verfahren zur Herstellung eines Nahrungsmittels, Verwendung von Fett zur Einbettung von Selen und ein Nahrungsmittel.The invention relates to a method for producing a food, use of fat for embedding selenium and a foodstuff.
Selen schützt als Bestandteil des Enzyms Glutathionperoxidase die Körperzellen vor Schädigung durch Oxidation und ergänzt bzw. ersetzt damit die Funktion von VitaminAs a component of the enzyme glutathione peroxidase, selenium protects the body cells from damage through oxidation and thus supplements or replaces the function of vitamin
E. Selen ist zudem ein wichtiges Element für die Funktion und Gesundheit derE. selenium is also an important element for the function and health of the
Schilddrüse sowie für ein intaktes Immunsystem. Beim Wiederkäuer wird Natriumse- lenit in den Vormägen in schlecht verwertbares Selenid umgewandelt, so dass dieThyroid gland as well as for an intact immune system. In ruminants, sodium selenite is converted into selenium in the roughing mills, so that the
Absorptionsrate auf 10-50% fällt, gegenüber dem Monogaster, bei dem bis zu 90% absorbiert wird.Absorption rate falls to 10-50%, compared to the monogaster, in which up to 90% is absorbed.
Nachteilig ist dabei auch, dass mehr als 50% der zugeführten Selenmenge somit durch die Selenumwandlung in den Vormagen verloren geht und über den Kot ausgeschieden wird, was zudem angesichts der grundsätzlichen Giftigkeit von Selen zu einer Umweltverschmutzung führen kann.Another disadvantage is that more than 50% of the amount of selenium supplied is thus lost by the selenium transformation in the forestomach and is excreted in the feces, which may also lead to environmental pollution in view of the fundamental toxicity of selenium.
Aufgabe der vorliegenden Erfindung ist es eine sichere, zuverlässige und gut auszunutzende Selenquelle insbesondere für Wiederkäuer bereitzustellen.Object of the present invention is to provide a safe, reliable and well-exploited source of selenium, especially for ruminants.
Als Lösung wird vorgeschlagen einjjVerfahren zur Herstellung eines Nahrungsmittels und/oder Nahrungsmittelzusatzstoffes, insbesondere für ein Tierfutter, wobei Selen, Insbesondere Natriumselenit und/oder Natriumselenat, zumindest teilweise in Fett eingehüllt wird, insbesondere in einen Fettmantel oder in eine Fettmatrix, insbesondere mittels eines Sprühverfahrens oder mittels eines Extrusionsverfahrens.A solution is proposed for the production of a food and / or food additive, in particular for animal feed, wherein selenium, in particular sodium selenite and / or sodium selenate, is at least partially encased in fat, in particular in a fat coat or in a fat matrix, in particular by means of a spraying process or by means of an extrusion process.
Durch das in der angegebenen Art hergestellte Nahrungsmittel ist dies gegen Umwelteinflüsse auf einfache Weise geschützt. Feuchtigkeit und Luft werden durch die Fettmatrix von den Zusatzstoffen abgehalten, was eine längere Lagerung ohne Wirkstoffverlust ermöglicht. Zudem wird beispielsweise ein Angriff im Pansen eines Wiederkäuers zunächst abgewehrt und die Zusatzstoffe erst im späteren Verdauungs- prozess im Darm - am Ort der Absorption - langsam, Stück für Stück freigegeben. Dies wird insbesondere dadurch ermöglicht, dass die Matrix auch im Inneren der hergestellten Nahrungsmittelteile die Zusatzstoffe jeweils in einzelnen kleinen Partikeln einschließt und diese dann erst nach und nach durch Abtragung der umgebenden Matrix freigesetzt werden.The food produced in the specified type this is easily protected against environmental influences. Moisture and air are through the Fat matrix prevented from the additives, allowing a longer storage without drug loss. In addition, for example, an attack in the ruminal rumen of a ruminant is initially blocked and the additives are released slowly, piece by piece, in the gut later in the digestive process - at the site of absorption. This is made possible, in particular, by the fact that the matrix also encloses the additives in the interior of the foodstuff parts produced in individual small particles, and these are then released only gradually by ablation of the surrounding matrix.
Die hierdurch mögliche Verbesserung der Selenverwertung liegt zum einen an der nahezu vollständigen Absorption und zudem an der zeitlich verlängerten Selen. - Anflutung im Stoffwechsel. Der Stoffwechsel wird also durch die langsamere Aufnahme nicht auf einmal mit einer zu hohen Menge des Stoffes belastet sondern es kann sich immer wieder ein Gleichgewicht einstellen, was eine bessere Verwertung ermöglicht und einen ausgewogenen und belastbaren Selenhaushalt unterstützt. Damit bleibt eine homöostatische Gegenreaktion aus, die einen temporären Selen- überschuss über den Harn ausscheiden würde. Es ist somit eine maximale Absorption und eine minimale Ausscheidung sowie eine optimale intermediäre Verwertung gegeben. Durch die erfindungsgemäß eingeschlossenen Selenpartikel ergab sich in Rinderversuchen eine Effizienzsteigerung der Selenverwertung um den Faktor 3. Zudem liegt das Selen nicht in einer organisch gebundenen Form vor, das zu einer Selenanreicherung im Körpergewebe führt, ohne wirksam zu sein.The possible improvement of the selenium utilization is due to the almost complete absorption and also to the time-prolonged selenium. - Flood in the metabolism. The metabolism is thus not burdened by the slower absorption at once with too much amount of the substance but it can always adjust a balance, which allows for better recovery and supports a balanced and resilient selenium. This leaves a homeostatic reaction that would eliminate a temporary excess of selenium through the urine. It is thus given a maximum absorption and a minimal excretion as well as an optimal intermediate utilization. The selenium particles included according to the invention resulted in an increase in the efficiency of selenium utilization by a factor of 3 in cattle trials. In addition, the selenium is not present in an organically bound form which leads to a selenium enrichment in the body tissue without being effective.
