Food waste and food by-products have gained considerable attention in recent years. Based on the principles of circular economy, these materials can be used for preparation novel biodegradable packaging preservation. Among matrices that been well exploited, poly-lactic acid (PLA) comprises a key material to fortified with by-products, as shown by numerous studies literature. In this context, aim present review was provide an overview literature most trends use PLA prepare films shelf-life extension foods animal or plant origin. The results showed origin has greatly expanded last 20 application led stability. However, there is still gap specific origin, such peels, seeds, gels (i.e., onion grape seed extract, pomace, prickly pear cladode gel) whey, collagen, gelatin), PLA-based films. review, which thematic issue ongoing doctoral study, examines challenges regard topic not extensively studied.

High-Efficiency and Low-Resistance Melt-Blown/Electrospun PLA Composites for Air Filtration

Polymers, Journal Year: 2025, Volume and Issue: 17(3), P. 424 - 424

Published: Feb. 6, 2025

Biodegradable polylactic acid (PLA) was used to fabricate nonwoven fabrics via the melt blowing process, followed by electrospinning deposit a nanofiber membrane. This composite process yielded PLA melt-blown/electrospun materials with excellent filtration performance. The effects of solution concentration and spinning duration on structure material performance were investigated. optimal produced using 10 wt.% prepared solvent mixture dichloromethane (DCM) N, N-dimethylformamide (DMF) in 75/25 weight ratio. parameters included 5 h, 18 kV voltage, 1.5 mL/h flow rate, 12 cm collection distance. resulting achieved efficiency 98.7%, pressure drop 142 Pa, an average pore size μm, contact angle 138.7°. These results provided for preparing materials. study highlights potential hydrophobic composites high low air resistance as environmentally friendly alternatives traditional non-degradable

Investigating the Effects of Bead Formation on the Physicochemical and Biological Properties of Electrospun Poly(lactic-co-glycolic Acid) (PLGA) Membranes: A Comparative Analysis

European Journal of Dentistry, Journal Year: 2025, Volume and Issue: unknown

Published: May 1, 2025

This study investigates the impact of bead formation on properties electrospun poly(lactic-co-glycolic acid) (PLGA) membranes, particularly mechanical strength, uniformity, and cell adhesion, challenging conventional belief that bead-free membranes are superior.Three types PLGA were fabricated: beaded (B), fibrous (F), a mixed (M) configuration beads fibers. Morphological, chemical, surface characteristics analyzed using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), water contact angle measurements. Human dental pulp stem cells (DPSCs) used to assess in vitro proliferation, viability across different membrane types.SEM imaging revealed distinct morphologies among produced via electrospinning. FTIR analysis no significant differences chemical composition membranes. Contact measurements indicated B M became more hydrophilic over time, while F remained relatively hydrophobic. All supported DPSCs growth, with facilitating deeper infiltration into scaffold, indicating enhanced integration. Viability assays proliferation after 7 days, demonstrating presence did not impair growth.These findings suggest may offer advantages, such as improved hydrophilicity infiltration, without compromising viability. challenges notion inherently superior highlights potential morphology optimizing scaffolds for biomedical applications.

Highly miscible bio-based poly(lactic acid)/acetylated cellulose ether ultrafiltration membranes with improved water permeances

Journal of Membrane Science, Journal Year: 2024, Volume and Issue: 711, P. 123195 - 123195

Published: Aug. 10, 2024

Biopolymer-based membranes are eco-friendly alternatives to petroleum-based membranes. However, biopolymers often require harsh membrane fabrication conditions due their low solubilities, which incompatible with general non-solvent-induced phase separation (NIPS). Thus, establishing mild blending for NIPS production is needed. This study developed ultrafiltration by poly (lactic acid) (PLA) and acetylated cellulose ether (ACE), both of derived from renewable resources, using under conditions. We investigated the effects PLA proportion on structural, chemical, thermal properties blend assessed polymer miscibility theoretical models. Results indicated excellent a single glass transition temperature. The 1:1 PL A/ACE demonstrated lowest water contact angle 45°, 35 % lower than that pure membrane. Additionally, its permeance was 179.4 LMH/bar, significantly higher 103.4 LMH/bar Flux recovery ratio at pH = 4 69.5 as compared 70.6 At 7, all could be fully recovered via physical washing, even those fouled bovine serum albumin. successfully fabricates PLA/ACE-based outstanding
