Some recent developments in the size and shape analysis of industrial polysaccharides in solution using sedimentation analysis in the analytical ultracentrifuge

摘要: Abstract 1. There is now a renaissance of interest in the application sedimentation methods to study food macromolecules and follows some significant developments instrumentation. 2. These are particularly relevant our understanding properties industrial or 'commercial' polysaccharides, molecules which inherently polydisperse thermo-dynamically non-ideal. 3. This short review article attempts establish contribution that velocity equilibrium making sizes, shapes heterogeneity industrially important polysaccharides dilute solution also indicates recent analysis gels, diffusion through matrices interactions involving these molecules. 4. The importance combining information from with complementary techniques such as viscometry, light scattering electron microscopy stressed. 5. Comments about potential impact new commercially available ultracentrifuge given.
