TL;DR: In this paper, a process for hemicellulose fractionation and purification from wheat straw and bran has been investigated, and the efficiency of a pilot scale process combining twin-screw extrusion and refining steps such as ultrafiltration and chromatography, to replace alcoholic precipitation was defined.
Journal ArticleDOI

Journal ArticleDOI
Parameters affecting enzyme-assisted aqueous extraction of extruded sunflower meal.
TL;DR: Agitation and addition of cellulases increased oil extraction yield, indicating that emulsification of oil and alteration of the geometry of the confining cellular matrix were important mechanisms for improving yields.
