Combined DLS/Raman provides New Molecular Insights of Complex Fluids

| Sponsored by Malvern Panalytical

In particular, this article demonstrates the correlation between molecular changes (Raman Spectroscopy) and microstructural evolution of rheological properties (DLS, DLS-optical microrheology) for the first time for surfactant-based wormlike micellar system. Whereby, Raman Spectroscopy provides information about the molecular structure and DLS-microrheology characterizes viscoelastic properties, the combination of data delivered allows for a deeper understanding of the molecular changes underlying the viscoelastic ones. The study illustrates the utility of the combined DLS, DLS-optical microrheology and Raman Spectroscopy in providing new molecular structural insights into the self-assembly process in complex fluids.

Dairy and Food Emulsions measurement

| Sponsored by Malvern Panalytical

The particle size of the fat droplets present in dairy and other food emulsions is important in defining properties such as flavor release, mouth feel and emulsion stability. Thus, a knowledge of the particle size is critical in defining the functionality and taste of different food emulsion products. Here we show how laser diffraction can be used to measure and understand the changes in size that occur during production and storage of dairy products. This in turn can lead to a better understanding of how product formulation and performance are linked.
