Polymers derived from renewable resources are now considered as promising alternatives to traditional petro-polymers they mitigate current environmental concerns (raw materials/biodegradability). d-limonene can be found in a variety of citrus, indeed is the main component citrus oils and one most important contributors flavor. The incorporation limonene PLA matrix was evaluated quantified by Pyrolysis Gas Chromatography Mass Spectrometry (Py-GC/MS). Transparent films were obtained after...
The migration of antioxidant (AO) agents, carvacrol and thymol, from polypropylene (PP) packaging films containing the studied compounds at 80 g/kg separately an equimolar mixture them into food simulants was investigated. Fast reliable analytical procedures were developed validated for analysis AOs in simulants. For aqueous simulants, solid phase extraction followed by GC–MS performed. Fatty directly analysed HPLC-UV isooctane ethanol 950 mL/L, respectively. release dependent on type...
Thymol and silver nanoparticles (Ag-NPs) were used to develop poly(lactic acid) (PLA)-based films with antioxidant antibacterial performance. Different amounts of thymol (6 8 wt%) 1 wt% Ag-NPs added PLA produce the active films. successfully identified in nanocomposite structures using spectroscopic techniques. A kinetic study was performed evaluate release from nanocomposites an aqueous food simulant (ethanol 10%, v/v) at 40 °C. The diffusion polymer matrix affected by presence...
In this study, yerba mate waste (YMW) was used to produce a kombucha beverage, and the obtained microbial cellulose produced as byproduct (KMW) reinforce mechanically recycled poly(lactic acid) (r-PLA) matrix. Microbial cellulosic particles were also in pristine for comparison (KMN). To simulate revalorization of industrial PLA products rejected during production line, subjected three extrusion cycles, resultant pellets (r3-PLA) then plasticized with 15 wt.% acetyl tributyl citrate ester...
The use of biopolymers obtained from renewable resources is currently growing and they have found unique applications as matrices and/or nanofillers in 'green' nanocomposites. Grafting polymer chains to the surface cellulose was also studied promote dispersion nanocrystals hydrophobic matrices. aim this study modify by grafting L-lactide ring-opening polymerization order improve compatibility effectiveness evidenced long-term stability a suspension poly(lactic acid)-grafted chloroform,...
The migration behaviour of low molecular weight compounds from food packaging materials is one the key issues in assessing possibility use such applications. aim this work was to study carvacrol (1% and 2% w/w) when added high-density polyethylene. All were exposed simulants olive oil distilled water separately at 40°C 25°C. Three significant variables influencing process considered: incubation temperatures, initial concentration antioxidant, type simulant (oil aqueous). amount migrating...
Nano-biocomposite films based on poly (lactic acid) (PLA) were prepared by adding thymol (8 wt.%) and a commercial montmorillonite (D43B) at different concentrations (2.5 5 wt.%). The antioxidant, antimicrobial, disintegration properties of all determined. A kinetic study was carried out to evaluate the release from polymer matrix into ethanol 10% (v/v) as food simulant. nanostructured networks formed in binary ternary systems interest controlling results indicated that diffusion through PLA...
