Impact of wheat bran dietary fiber on gluten and gluten

Visualization of the gluten network microstructure of dough is crucial to gain knowledge about the interactions of its various ingredients In this study various techniques including mainly microscopy imaging were applied to examine the effect of wheat bran dietary fiber (WBDF) on gluten (G) and gluten-starch (G+S) microstructure

Intended use: RIDASCREEN Gliadin is a sandwich enzyme immunoassay for the quantitative analysis of contaminations by prolamins from wheat (gliadin) rye (secalin) and barley (hordein) in raw products like flours (buckwheat rice corn oats teff) and spices as well as in processed food like noodles ready-to-serve meals bakery products sausages beverages and ice cream

Visualization of Gluten and Starch Distributions in Dough

Wheat flour dough consists of two immiscible phases: the gluten phase and the liquid phase containing water-soluble compounds and starch 3) The gluten phase serves as the dough skeleton and dominates the rheological behavior of wheat flour dough during extensive defor-mation 1) while the starch in the liquid phase acts as a filler 4)

US5851301A

Methods for separation of wheat flour into protein and starch fractions are described Wheat flour is (1) mixed with water to hydrate the flour and form a cohesive batter or dough (2) chilled and (3) mixed and washed with chilled ethanol to separate it into protein and starch fractions Wheat protein fractions that are equivalent in yield and protein concentration to fractions produced by
