Abstract
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) structure with a lattice

parameter of 70 Å. In the WG films with NH4OH, a highly polymerized

protein pattern with intimately mixed glutenins and gliadins bounded

through SH/SS interchange reactions was found. A large content of β-

sheet structures was also found in these... (More)

sheet structures was also found in these films, and the film structure was

oriented in the extrusion direction. In conclusion, this study highlights

complexities of the supramolecular structures and conformations of wheat

gluten polymeric proteins in biofilms not previously reported for biobased

materials. (Less)
