abstract = {We investigate by time-resolved synchrotron ultra-small
X-ray scattering the dynamics of liquid–liquid
phase-separation (LLPS) of gluten protein suspensions
following a temperature quench. Samples at a fixed
concentration (237 mg ml−1) but with different protein
compositions are investigated. In our experimental
conditions, we show that fluid viscoelastic samples depleted
in polymeric glutenin phase-separate following a spinodal
decomposition process. We quantitatively probe the late
stage coarsening that results from a competition between
thermodynamics that speeds up the coarsening rate as the
quench depth increases and transport that slows down the
rate. For even deeper quenches, the even higher
viscoelasticity of the continuous phase leads to a
“quasi” arrested phase separation. Anomalous
phase-separation dynamics is by contrast measured for a gel
sample rich in glutenin, due to elastic constraints. This
work illustrates the role of viscoelasticity in the dynamics
of LLPS in protein dispersions.},
