An amino-acid iodine complex, viz. amino-acid amino-carboxyl iodine
complex, was provided wherein its coordinate center is iodine molecule,
complex reagent is amino-acid, sites of complexing reaction are amino and
carboxyl groups of amino-acid. The complex can be used for the production
of feedstuff, food additive, disinfectant, antiseptic and medicament.
Also provided is a method for the production of said complex comprising
opening the inner-complex ring of amino-acid by acid catalysis and
allowing the amino-acid to combine with iodine molecule to form an
amino-acid amino-carboxyl iodine complex; because amino-acid is a
nutriment and amino-carboxyl complex is achieved, their introduction not
only increases the nutritional function of the complex and improves the
stability of iodine, but also is beneficial to the environment protection
and enhances the disinfecting activity against viruses and bacteria.
