abstract = {We investigated the effect of the NaCl concentration
(0.3–2M) on the structure and dynamics of hen egg yolk at
room temperature andduring thermal gelation at temperatures
in the range of 66–90 ○C utilizing low-dose x-ray photon
correlation spectroscopy in ultra-smallangle x-ray
scattering geometry. With an increase in the salt
concentration, we observe progressive structural and dynamic
changes at roomtemperature, indicating the disruption of
yolk components such as yolk-granules and yolk-plasma
proteins. Temperature- and salt-dependentstructural and
dynamic investigations suggest a delay in the gel formation
and aggregation of yolk low-density lipoproteins with
increasingionic strength. However, the time–temperature
superposition relationship observed in all samples suggests
an identical mechanism underlyingprotein
aggregation–gelation with a temperature-dependent reaction
rate. The sol–gel transition time extracted from kinetic
and dynamicinformation follows Arrhenius’s behavior, and
the activation energy (460 kJ/mol) is found to be
independent of the salt concentration.},
