Abstract: The production and utilization of novel water soluble amylose-complexes using fatty ammonium and carboxylate salts will be presented. Amylose complexation of suitable ligands results in complete inhibition of starch retrogradation and improved water solubility of the final product. The properties and utilization of the amylose complexes are reliant on the bound ligand. Complexes have ligand and pH dependent properties and can be utilized as emulsifying agents for oils. Carboxylate salt complexes can be used to produce co-polymer blends with cellulose ethers to provide films or coatings with increased gas barrier properties and improved thermal stability. Complexes produced from ammonium salts can be utilized to produce antimicrobial films which dramatically inhibit the fungal pathogen, Fusarium sambucinum in potatoes. Additionally, treatment of wood with the fatty ammonium salt inclusion complexes results in increased water resistance and dimensional stability of the treated wood.
