In this paper, a new method for the synthesis of the sulfated starch-casein complex is proposed. The resulting new complex was characterized by FTIR and UV-spectroscopy. It has been shown by FTIR spectroscopy that both nitrogen atoms and the carboxyl group of amino acid residues are protonated in casein. The sulfated starch-casein complex obtained in this work may have biological activity, as well as its analogues isolated from plants, fungi, and microorganisms, as well as synthesized in laboratory conditions.
