Problems solved by technology

[0002] Trace elements are one of the essential nutrients in the growth process of animals. Initially, trace elements were directly added to the feed in the form of inorganic salts, such as ferrous sulfate and copper sulfate. In the digestive tract, it is easy to form corresponding salts with low solubility with phytic acid anions and oxalate anions, which are common in feed, through biochemical reactions in animals, and are not easily absorbed by the intestines

Abstract

The invention discloses a preparation method of methionine-chelated iodine for feed and belongs to the field of feed additives. Raw materials adopted for producing methionine-chelated iodine include methionine, iodine and a 10% sodium hydroxide water solution. Through preparation of the water solution, a chelation reaction of methionine and iodine, separation, drying and other processes, methionine-chelated iodine is prepared and has the technical advantages that industrial production of methionine-chelated iodine is achieved, the processes are simple, the generation cost is low, there is no need to add important equipment, the operation is convenient, and popularization is easy. The feed prepared by methionine-chelated iodine has high palatability and absorption rate and is easy to transport, and iodine has the functions of promoting biological oxidation, regulating synthesis and decomposition of protein, promoting metabolism of sugar and fat, regulating metabolism of water and salt,promoting the absorption and utilization of vitamins, enhancing the activity of enzymes, facilitating growth and development and the like. Therefore, iodine is one of indispensable trace elements in animal feed, and the absorption rate after iodine is chelated with amino acids is greatly increased, so that the growth performance of animals is improved.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a preparation method of methionine chelated iodine for feed. Background technique [0002] Trace elements are one of the essential nutrients in the growth process of animals. Initially, trace elements were directly added to the feed in the form of inorganic salts, such as ferrous sulfate and copper sulfate. In the digestive tract, it is easy to form corresponding salts with low solubility with the common phytic acid anions and oxalate anions in the feed through biochemical reactions in animals, which are not easily absorbed by the intestinal tract. With the development of the feed industry, amino acid and trace element chelates such as amino acid chelated iron, amino acid chelated copper, amino acid chelated manganese and amino acid chelated iodine have been gradually developed. It is characterized by stability, high efficiency, It has low toxicity, is easy to digest and absorb in ...
