Use of FTIR to study secondary structure of texturized plant proteins by high moisture extrusion cooking, a comprehensive review.

Fourier-Transform Infrared spectroscopy (FTIR) is often used by researchers to understand the texturization mechanisms of plant proteins. High Moisture Extrusion-Cooking (HMEC) is the main process used for their texturization by heating, mechanical shearing, and subsequent cooling of a high-moisture mixture, which causes denaturation and restructuration of proteins, resulting in an anisotropic product, commonly called "meat analog". Researchers try to link the properties of extrudates to the secondary conformation of proteins, which are supposed to aggregate and align in the flow direction within the die.

Impact of thermomechanical pretreatment by twin-screw extrusion on the properties of bio-based materials from sugarcane bagasse obtained by thermocompression.

The aim of this study was to produce binderless materials by thermocompression from lignocellulosic biomass pretreated using twin-screw extrusion. The impact of twin-screw extrusion pretreatment on sugarcane bagasse (SCB) was evaluated, along with the effects of two associated parameters: the liquid-to-solid (L/S) ratio and the screw profile, using three different mechanical shear rates. It was shown that twin-screw extrusion pretreatment resulted in materials with improved properties as compared to those obtained with untreated SCB.

Eco-Design of Thermopressing through Induction of 100% Coriander-Based Fiberboards: Optimization of Molding Conditions.

The hot pressing process for 100% coriander-based fiberboards was optimized using an induction RocTool system, which offers rapid mold heating and cooling. The fiberboards were made using deoiled press cake as a protein binder and extrusion-refined straw as reinforcement. Doehlert's experimental design was used to evaluate the influence of pressure (10-50 MPa), molding time (60-300 s), and mold temperature (155-205 °C) on fiberboard properties, energy consumption, cost, and environmental impact.

Aqueous Pretreatment of Lignocellulosic Biomass for Binderless Material Production: Influence of Twin-Screw Extrusion Configuration and Liquid-to-Solid Ratio.

This study was carried out to investigate the continuous aqueous pretreatment of sugarcane bagasse (SCB) through twin-screw extrusion for a new integrated full valorization, where the solid residue (extrudate) was used for the production of bio-based materials by thermocompression and the filtrate for the production of high-value-added molecules. Two configurations, with and without a filtration module, were tested and the influence of the SCB composition and structure on the properties of the materials were determined. The impact of the liquid-to-solid (L/S) ratio was studied (0.

Polyhydroxy-3-Butyrate (PHB)-Based Composite Materials Reinforced with Cellulosic Fibers, Obtained from Barley Waste Straw, to Produce Pieces for Agriculture Applications: Production, Characterization and Scale-Up Analysis.

Cellulosic fibers obtained from Barley straw were utilized to reinforce PHB. Four different processed fibers were employed as reinforcing material: sawdust (SW), defibered (DFBF), delignified (DBF), and bleached (BBF) fibers. The composite was processed from two different perspectives: a discontinuous (bach) and an intensification process (extrusion).
