Mitunter werden diese Spurenelemente auch den vitaminhältigen Beifuttermitteln zugesetzt.
Die bisher verwendeten Jodsalze haben verschiedene Nachteile, die zu beseitigen der Zweck des erfindungsgemässen Verfahrens ist.

Wie aus der Jodometrie bekannt ist, vermag eine

Stärke (Amylose), begünstigt durch die Anwesenheit von Kaliumjodid, Jod unter Bildung eines beau gefärbten Additionsproduktes zu binden (Mylius).
Bei dem erfindungsgemässen Verfahren handelt es sich um eine Umsetzung von Jod mit in jeder Hinsicht unveränderter, also unverkleisterter, trokkener Stärke.
Das sich daraus ergebende Produkt ist weitgehend stabil und gibt weder freies Jod noch Alkalijodid ab, was gegenüber andern Jodverbindungen den Vorteil hat, dass man ohne Gefahr einer chemischen Umsetzung mit Metallsalzen oder Vitaminen, geeignete Mineralstoff- oder Vitaminvor- mischungen für Futtermittel herstellen kann. Ausserdem ermöglicht seine trockene, feinpulverige Beschaffenheit eine vorzügliche Dosierung und Verteilung im Futter.
B e i s p i e 1 1 : 89, 6 Gew.-Teile Maisstärke werden mit einer wässerigen Lösung von 1, 4 Gew.Teilen Natriumkarbonat homogen vermischt. Anschliessend sprüht man eine alkoholische Lösung von 10 Gew.-Teilen Jod auf das laufende Mischgut bis eine gleichmässige Verteilung erreicht ist.

PATENTANSPRÜCHE :

Added in the form of salts.
Sometimes these trace elements are also added to the vitamin-containing feedstuffs.
The iodine salts used hitherto have various disadvantages, which the purpose of the method according to the invention is to eliminate.

Starch (amylose), facilitated by the presence of potassium iodide, binds iodine with the formation of a brightly colored addition product (Mylius).
The process according to the invention is a reaction of iodine with dry starch which is unchanged in every respect, that is to say ungelatinised.
The resulting product is largely stable and emits neither free iodine nor alkali iodide, which has the advantage over other iodine compounds that suitable mineral or vitamin premixes for animal feed can be produced without the risk of chemical reaction with metal salts or vitamins. In addition, its dry, fine powdery texture enables excellent dosage and distribution in the feed.
B e i s p i e 1 1:89, 6 parts by weight of corn starch are mixed homogeneously with an aqueous solution of 1.4 parts by weight of sodium carbonate. An alcoholic solution of 10 parts by weight of iodine is then sprayed onto the running mix until it is evenly distributed.

Temperature mixed well. Then 1.8 g of hydrogen peroxide (30%) are dissolved in 10 cm3 of alcohol and sprayed onto the running mix. The black-violet, homogeneous product is dried at 50-600 C, finely ground and sieved.
PATENT CLAIMS:
1. A process for the production of a stable dry iodine-starch compound as an additive for mineral supplementary feed, characterized in that elemental iodine in the form of an alcoholic solution with the simultaneous presence of an alkali salt with unchanged dry starch (e.g. wheat starch, potato starch, corn starch etc.) is made to react, whereupon the re-
