Hydrodynamic dispersion in beta-lactoglobulin gels measured by PGSE NMR
Journal article, 2011
The displacement scale dependent molecular dynamics of solvent water molecules flowing through beta-lactoglobulin gels are measured by pulse gradient spin echo (PGSE) nuclear magnetic resonance (NMR). Gels formed under different pH conditions generate structures which are characterized by magnetic resonance imaging (MRI) and PGSE NMR measured dynamics as homogeneous and heterogeneous. The data presented clearly demonstrate the applicability of the theoretical framework for modeling hydrodynamic dispersion to the analysis of protein gels.
