Resumen
In this work, the formation of capsules in xanthan gum and complexing solutions of Fe III is structurally evaluated. These capsules have a spheroid shape that, when dried, collapse into disc shapes. These spheroids are made up of microspheres that partially explain this collapse. The backscattered SEM image shows areas rich in Fe and others poorer in this metal, the EDX analysis confirms this. FTIR chromatograms show a clear shift at approximately 1620 cm-1 due to the formation of the xanthan gum-Fe III complex. This work also proposes a structure, theoretically demonstrated, between xanthan gum and Fe III, which can explain what the biopolymeric structure bending procedure is like due to the presence of Fe III, a model called TransbiHook.
