Long-Range Atomic Order on Double-Stepped AlO(0001) Surfaces.

The deterministic preparation of highly ordered single-crystalline surfaces is a key step for studying and utilizing the physical properties of various advanced materials. This paper presents the fast and straightforward preparation of vicinal AlO(0001) surfaces with micrometer-scale atomic order. Crisp electron-diffraction spots up to at least 20 order evidence atomic coherence on terraces with widths exceeding 1 μm.

Impact of food structure on the compatibility of heated WPI-pectin-complexes in meat dispersions.

Process-stable complexes composed of whey protein isolate (WPI) and sugar beet pectin have great potential as structuring agents or fat replacers in foods. The current study investigates the compatibility of heated WPI : pectin complexes in different meat matrices. Spreadable raw-fermented sausages and sliceable emulsion-type sausages were therefore manufactured containing biopolymer complexes with various WPI : pectin ratios r (2 : 1, 8 : 1).

Mixing behaviour of WPI-pectin-complexes in meat dispersions: impact of biopolymer ratios.

Particulated complexes composed of oppositely charged biopolymers were incorporated into highly concentrated protein matrices as potential fat replacers and structuring agents. A multistep procedure was therefore utilized to generate process-stable complexes, which were subsequently embedded into emulsion-type sausages, whereas macro- and microstructural properties were then assessed. Firstly, stock WPI and sugar beet pectin solutions were mixed under neutral conditions (pH 7) at various biopolymer ratios r (2 : 1, 5 : 1, 8 : 1).
