An advanced design of the analytical ultracentrifuge with multiwavelength emission detection (MWE-AUC) is presented which offers outstanding performance concerning the spectral resolution and range flexibility as well as the quality of the data acquired. The excitation by a 520 nm laser is complemented with a 405 nm laser. An external spectrograph with three switchable tunable gratings permits optimisation of the spectral resolution in an order of magnitude range while keeping the spectral region broad.

Article Synopsis
  • * Proteins can change structure based on factors like temperature, pH, and their environment, leading to potential aggregation when adsorbed onto surfaces.
  • * Using sum frequency generation (SFG) spectroscopy, researchers examined how pH affects the electrical properties around model proteins attached to a hydrophobic surface, finding that the protein's stability is linked to its amino acid makeup and hydrophobic characteristics.

Hypothesis: High hydrostatic pressure treatment causes structural changes in interfacial-active β-lactoglobulin (β-lg). We hypothesized that the pressure-induced structural changes affect the intra- and intermolecular interactions which determine the interfacial activity of β-lg. The conducted experimental and numerical investigations could contribute to the mechanistic understanding of the adsorption behavior of proteins in food-related emulsions.
