Structure and Morphology of Wheat Gluten Films: From Polymeric Protein Aggregates toward Superstructure Arrangements
Evaluation of structure and morphology of extruded wheat gluten (WG) films showedWGprotein assemblies elucidated on a range of length scales from nano (4.4 Å and 9 to 10 Å, up to 70 Å) to micro (10 μm). The presence of NaOH in WG films induced a tetragonal structure with unit cell parameters, a = 51.85 Å and c = 40.65 Å, whereasNH4OHresulted in a bidimensional hexagonal close-packed (HCP) structur
