Jerusalem artichoke straw - Opis:
- The paper presents the effect of extrusion-cooking conditions (moisture content and screw speed) on the physical properties of extruded Jerusalem artichoke straw. A single screw extruder was used for straw processing. Shredded Jerusalem artichoke straw moistened to 30, 40, and 50% was subjected to an extrusion-cooking process at various screw speeds (70, 90, and 110 rpm). Selected physical properties and pasting profile were tested. Significant differences were observed depending on the moisture content of the samples and the various screw speed on their physical properties. Notably, increased moisture content lowered the specific mechanical energy, increased processing efficiency, water solubility, peak viscosity and breakdown. The maximum efficiency and the highest breakdown was observed for the sample with 50% moisture content processed at an extruder screw speed of 90 rpm. The sample obtained at 30% moisture and at 90 rpm was characterized by the lowest efficiency and hot paste viscosity, and the highest specific mechanical energy. The results showed that the extrusion-cooking process yielded desirable changes to the structure of the analysed lignocellulosic biomass.
