Structural FT-IR and [sup.13]c cp/mas nmr investigation of native starch with plasticizers before and post extrusion process

Structural aspects of native corn starch samples with plasticizers are investigated by FT-IR, [sup.13]C CP/MAS NMR and XRD methods before and after extrusion process. The crystalline A, B and V - types structural phases prevail before extrusion in the prepared samples. The amorphous phase becomes do...

Zusammenfassung:Structural aspects of native corn starch samples with plasticizers are investigated by FT-IR, [sup.13]C CP/MAS NMR and XRD methods before and after extrusion process. The crystalline A, B and V - types structural phases prevail before extrusion in the prepared samples. The amorphous phase becomes dominant in both recent prepared formula and control specimen sample after extrusion. Keywords: starch, extrusion, FT-IR, CP/MAS NMR, XRD
