Natural Clays as Potential Amino Acids Carriers for Animal Nutrition Application

This study has the main purpose of testing natural carriers as more sustainable alternatives to polymeric coating. New clay-based hybrid organic–inorganic materials have been prepared. An innovative procedure for intercalation bioactive molecule is proposed. The synthesis process implies use mild operating conditions and does not require organic reactants or solvents. Moreover, carriers, milder environmentally friendly conditions, fulfill requirement a mostly safe, greener production. capture release properties final material mainly depend on carrier morphology. Large zeolite content in mineral clays can favor very large methionine loadings, but due trapping mechanism, typical these structures, zeolites prevent satisfactory condition physiological condition. Freundlich adsorption model found be able predict behavior. Once proper selected, preparation guarantees protection amino acid right form. Neither structure inorganic matrix nor was changed process. Methionine detected its zwitterionic form, showing IR bands only slightly affected by interaction. Further studies bioaccessibility intestinal absorption from methionine–Adsorbene (MET–ADS) are required optimize application clay in-field animal nutrition.
