Abstract

Grazing incidence small angle X-ray scattering with a micrometer sized x-ray beam (so called micro-beam GISAXS, μGISAXS) is used to investigate the microstructure of casein films. Casein micelles treated with rennet enzyme tend to segregate on the surface into a enzyme treated and untreated phase. The biphasic microstructure is monitored by optical microscopy and analyzed by high resolution μGISAXS scans. Furthermore μGISAXS scans provide the possibility to locate highly ordered areas on the casein film surface and to investigate the molecular packing. A simulation via an elastic scattering approach is used to deduce size, dispersion and nearest neighbor distance of the casein micelles embedded in solution casted films. The GISAXS pattern of the highly ordered layer structure of a casein film preparation is shown.
