Water pollution is one of the most serious problems worldwide. Nanocellulose-based aerogels usually show excellent adsorption capacities due to their high aspect ratio, specific surface area and charge, making them ideal for water purification. In this work, (ligno)cellulose nanofibers (LCNFs/CNFs) from wheat straw residues were obtained using two types pre-treatments: mechanical (Mec) TEMPO-mediated oxidization (TO), obtain different consistency (0.2, 0.4, 0.6 0.8) bioaerogels, as dye...
This work evaluates the preparedness of packaging industry towards more circular, sustainable solutions for fresh meat and fish. The term bioplastic is ill-defined, creating confusion between all stakeholders in value chain. implementation as food contact material will only occur when there are demonstrated that can equally or better protect fish from spoilage, compared to conventional plastic. Price, supply chain availability, machinability, safety also be key shift fossil bioplastic....
Abstract The extensive use of non‐biodegradable bioplastics and fossil‐based plastics in food packaging presents a significant environmental challenge. Consequently, there has been growing interest exploring agricultural biomass as potential source for formulating biocomposites due to the substantial amount lignocellulosic residue generated. This study explores utilization avocado pruning (APR) isolating lignocellulose fibers their application replacement reinforcement material bio‐based...
Due to the overuse of petroleum-derived polymers and consumer demand for nutritious healthy products that can maintain their quality over longer periods time, there is a need new sustainable packaging systems fulfill these requirements. Lignocellulosic biomass, particularly agricultural pruning residues, offer great potential obtaining biopolymers through biorefining processes. In this study, raspberry residues were used produce lignocellulose nanofibers (LCNF) cellulose (CNF), by varying...
The growing demand for plant fiber-reinforced composites offers new opportunities to compete against glass fiber (GF)-reinforced composites, but their performance must be assessed, revised, and improved as much possible. This work reports on the production flexural strength of from polypropylene (PP) hemp strands (20–50 wt.%), using maleic anhydride-grafted PP (MAPP) a compatibilizer. A computational assessment reaction between cellulose MAPP suggested formation only one ester bond per...
The search for packaging alternatives that reduce the presence of non-biodegradable plastics in water is a focus much research today. This fact, together with increasing demand active capable prolonging shelf life foodstuffs and rise use natural biopolymers such as cellulose, motivate present work. work evaluates CMC films loaded gallic acid reinforced (ligno)cellulose nanofibres from various agricultural residues candidates food packaging. first stage study involved evaluation different...
An innovative colloidal approach is proposed here to carry out the customized functionalization of TEMPO-Oxidized Cellulose Nanofibers (CNF) incorporating non-noble inorganic nanoparticles. A heterocoagulation process applied between delignified CNF and as-synthetized CuO nanoparticles (CuO NPs) formulate mixtures which are used in preparation aerogels with antibacterial effect, could be manufacture membranes, filters, foams, etc. The involved components formulated blending, NPs, were...
The involved components of formulated blending, CNF and CuO NPs, were individually obtained by using a biorefinery strategy for agricultural waste valorization together with an optimized chemical precipitation, assisted ultrasounds. optimization synthesis parameters NPs have avoided the presence undesirable species which usually requires later thermal treatment associated costs. aerogels-based structure, conventional freeze-drying, acted as 3D support providing good dispersion within...
The impact of a coating solution containing chitosan, lignocellulosic nanofibers (LCNF), and raspberry leaf extract on strawberry quality was assessed. Strawberries were coated, inoculated with Aspergillus flavus (a major aflatoxin producer), stored at 5 ± 1 °C for 16 days. An automated fruit evaluation system developed, daily images taken analysis. ImageJ software used to evaluate colour, size loss, fungal damage. Coating significantly reduced coated strawberries showing 18.4 12.8% loss...
This review explores the agri-food residues of tomato and strawberry as sources bacteria with bio-protective potential against different pathogenic spoilage microorganisms for enhancing product shelf life improving food safety. A comprehensive research highlights that Pseudomonas (e.g., P. fluorescens) Bacillus B. subtilis) are relevant genera in microbiota both plants, opposed to lactic acid which a minority plants. Interestingly, those dominant microbial groups have been reported exhibit...
Sustainable Food Packaging Confronted with the environmental challenge posed by non-biodegradable bioplastics and fossil-based plastics in food packaging, article number 2300600, Quim Tarrés, Eduardo Espinosa, co-workers introduce a pioneering solution. By harnessing avocado pruning residue (APR) as natural fiber source, research presents sustainable alternative to bio-based polyethylene. This innovative method suggests APR's promising role shaping future landscape of environmentally...
Abstract Superabsorbent bio-aerogels were developed from TEMPO-oxidized cellulose nanofibers (isolated vegetables lignocellulosic residues) and two different commercial chitosan reactants (low high molecular weight) by polyelectrolyte complex formation at room temperature. Three thickness values considered, aging times employed, thus leading to twelve samples. Remarkably, no crosslink agents nor organic solvents used. All the materials characterized deeply studied. The components strongly...
