Normalized USAXS intensity from casein micelle suspensions (skimmed milk) at two different concentrations. For a comparison the corresponding data measured using a 10 m pinhole SAXS instrument are also shown. Bonse–Hart USAXS allows the structure and interactions between the large globular micelles, which form a turbid suspension in the visible region, to be determined. The continuous line is a fit to the unified scattering function with the following parameters: radius of gyration ∼130 nm; polydispersity index ∼7; corresponding to an average radius of about 60 nm. |
