Description
Verfahren zur Herstellung von Kunsteis Es ist bekannt, zur Herstellung von Kunsteis steriles Wasser zu benutzen, das z. B. durch -oligodynamische Behandlung keimfrei gemacht worden ist. Durch derartiges Kunsteis werden zwar von den damit zu konservierenden Nahrungsmitteln, z. B. Fischen, Infektionsquellen ferngehalten, jedoch wird keine über die Kältewirkung hinausgehende Konservierung erreicht.Process for the production of artificial ice It is known for the production to use sterile water from artificial ice, e.g. B. by oligodynamic treatment has been made sterile. With artificial ice like this, those with it foods to be preserved, e.g. B. Fish, sources of infection kept away, however, no preservation beyond the cold effect is achieved.
Es war bisher nicht möglich, Kunsteis mit Konservierungsmitteln zu versetzen, um so -die konservierende Wirkung des Eises zu erhöhen. Versucht man, Lösungen von Konservierungsmitteln zum Gefrieren zu bringen, so stellt man fest, daß sich reines Eis ausscheidet, bis eine konzentrierte Lösung des Konservierungsmittels übrigbleibt, die dann gegebenenfalls bei noch tieferer Temperatur erstarrt. Eine gleichmäßige Verteilung des Konservierungsmittels gelingt auf diese Weise nicht, es sei denn, man gäbe gewisse kolloide unlösliche Stoffe hinzu.So far it has not been possible to add preservatives to artificial ice to increase the preservative effect of the ice. One tries, Freezing preservative solutions is found to be that pure ice separates, until a concentrated solution of the preservative remains, which then possibly solidifies at an even lower temperature. One Even distribution of the preservative does not succeed in this way, unless you add certain colloidal insolubles.
Es wurde nun gefunden, daß Lösungen von Hexamethylentetramin überraschenderweise bei der üblichen Gefriertechnik gleichmäßig erstarren, so daß sich in allen Teilen des Eisblocks ein gleichmäßiger, dem ursprünglichen gleicher Gehalt an Ilexamethylentetramin vorfindet. Ein derartiges Eis ist hervorragend zum Konservieren von leicht verderblichen Lebensmitteln, z. B. Fischen, geeignet, damit dem Eis zusammen das Konservierungsmittel gleichmäßig verteilt werden kann.It has now been found that solutions of hexamethylenetetramine surprisingly solidify evenly with the usual freezing technique, so that in all parts of the ice block has a more uniform ilexamethylenetetramine content that is the same as the original finds. Such ice cream is excellent for preserving perishable items Food, e.g. B. fishing, suitable so that the ice cream together the preservative can be evenly distributed.
Die Menge an Hexamethyientetramin richtet sich nach den Erfordernissen des Einzelfalls; ein Gehalt von etwa i % hat sich z. B. für die Fischkonservierung bewährt.The amount of hexamethylene tetramine depends on the requirements of the individual case; a content of about i% has z. B. for fish preservation proven.
