Abstract A trilayer film based on thermoplastic starch (TPS) for the core layer and poly(ε-caprolactone) (PCL) skin layers was obtained by coextrusion. Ascorbic acid iron powder were added at respectively 15% 1.5% w/w in TPS their capacity to act as oxygen scavenger, making usable active food packaging. This study demonstrates that these compounds also play a role interactions between different layers. FTIR measurements show ascorbic migrates interface PCL, where it acts compatibiliser both...
The aim of this study was to develop new surfactants for membrane protein solubilization, from a natural, biodegradable polymer: the polysaccharide pullulan. A set amphiphilic pullulans (HMCMPs), differing in hydrophobic modification ratio, charge and nature chains introduced, were synthesized tested solubilization experiments with outer membranes Pseudomonas fluorescens. proteins precipitated, then resolubilized various HMCMPs. decyl alkyl chain (C(10)) graft that gave highest level...

This study describes the elaboration and characterization of plasticized starch composites based on lignocellulosic fibers. The transformation native to (TPS) preparation TPS blends were performed with a new lab-scale mixer an original concept. Firstly, morphology chemical composition flax shives analyzed better understand intrinsic properties these natural fillers. Then, impact processing parameters (temperature, speed screw) quality structural examined by SEM DRX. After that, we focused...
An innovative mixing device RMX (Reactor/elongational flow MiXer), based on an elongational flow, is used to formulate new biocomposites Doum palm fiber (at various proportions) and PLA polymer. Due its high has the ability mix immiscible products disperse solid phase (fiber) in viscous phase. The morphological aspect of PLA/Palm composites shows a good appearance orientation dispersive efficiency as confirmed by X‐ray tomography. For higher content, porosity rate decreases from 19% for...
Amphipathic polymers derived from polysaccharides, namely hydrophobically modified pullulans, were previously suggested to be useful as polymeric substitutes of ordinary surfactants for efficient and structure-conserving solubilization membrane proteins, one such polymer, 18C(10), was optimized proteins bacterial outer membranes (Duval-Terrie et al. 2003). We asked whether a similar ability solubilize could also demonstrated in eukaryotic membranes, sarcoplasmic reticulum (SR) fragments, the...
Abstract Summary: A new biodegradable thermoplastic material based on a wheat flour by‐product has been developed. The influence of various additives (glycerol, silica) and fibers (flax, cotton, hemp) the mechanical properties investigated. development expanded materials is also presented.
Abstract Summary : A new biodegradable thermoplastic material based on a wheat flour by‐product has been developed. The influence of protein content in the mechanical properties investigated. For between 4% and 10%, no was evidenced, whereas beyond 10% w/w proteins flour, agro‐based materials decrease, thus confirming advantage using (i.e. with below 8% w/w).
To bring surface hydrophobicity to thermoplastic starch (TPS) materials for food packaging, fatty acid esters (FASE), specifically tri-laurate, were incorporated into TPS formulations. A total of three different ratios FASE (2%, 5% and 10%) added the formulation evaluate influence onto physico-chemical properties TPS/FASE blends, i.e., hydrophobicity, dynamic vapor sorption (DVS), tensile behaviors. Blending with leads more hydrophobic materials, whatever ratio, initially measured contact...
