Abstract The green methodologies of nanoparticles with plant extracts have received an increase interest. Copper oxide (CuO NPs) been utilized in a many applications the last few decades. current study presents synthesis CuO NPs aqueous extract Morinda citrifolia as stabilizing agent. leaf was mixed solution copper sulphate (CuSO 4 ·5H 2 O) and sodium hydroxide catalyst. UV–visible spectroscopy, FTIR, XRD, SEM, TEM, EDAX analysis were performed to synthesized NPs. Particle size distribution measured dynamic light scattering. highly stable, sphere-like, particles from 20 50 nm. Furthermore, as-formed shown strong antibacterial activity against Gram-positive bacteria ( Bacillus subtilis, Staphylococcus aureus ), Gram-negative Escherichia coli ). revealed similar trend analysed for antifungal activity. zone inhibition fungi evaluated Aspergillus flavus (13.0 ± 1.1), niger (14.3 0.7), Penicillium frequentans (16.8 1.4). According results this investigation, may be used biomedicine replacement agent biological applications.

Nanotechnology: Current applications and future scope in food packaging systems

Measurement Food, Год журнала: 2023, Номер 13, С. 100131 - 100131

Опубликована: Дек. 31, 2023

Food packaging has shown a considerable deal of interest in the use nanotechnology. The current landscape nanotechnology food involves incorporation nanomaterials, such as nanoparticles and nanocomposites, into materials to achieve specific functionalities. These functionalities include improved barrier properties, antimicrobial activity, sensing capabilities. Nanoparticles, silver titanium dioxide, have been utilized impart thereby reducing risk contamination extending shelf life perishable foods. So, enhanced presentation, innovative packaging, smart packaging—all which support preservation quality traceability throughout supply chain—are developed using nanoparticles. Therefore, this article primarily emphasized on synthesis various techniques including, electrospinning, mechanical milling, etching laser ablation etc., characterization based organic inorganic sources. Additionally, nanoemulsion their application covered study. Apart from this, toxicological effect investigated with associated product. when developing materials, it's critical investigate migration interactions polymer matrix since high surface area volume ratio might sometimes be cause nanoparticle toxicity.

Chitosan-Based Films Blended with Tannic Acid and Moringa Oleifera for Application in Food Packaging: The Preservation of Strawberries (Fragaria ananassa)

Polymers, Год журнала: 2024, Номер 16(7), С. 937 - 937

Опубликована: Март 29, 2024

Biobased plastics provide a sustainable alternative to conventional food packaging materials, thereby reducing the environmental impact. The present study investigated effectiveness of chitosan with varying levels Moringa oleifera seed powder (MOSP) and tannic acid (TA). Chitosan (CS) biocomposite films acted as cross-linker, served reinforcement. To enhance film performance, was introduced at various loadings 1.0, 3.0, 5.0, 10.0 wt.%. Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy analyses were performed structure morphology CS/TA/MOSP films. results confirmed that chitosan/TA wt.% MOSP produced lightly miscible droplet/matrix structure. Furthermore, mechanical properties, swelling, water solubility, optical barrier, contact angle properties also calculated. With increasing contents, films’ antimicrobial antifungal activity increased level; all observed bacteria [Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Aspergillus niger (A. niger), Candida albicans (C. albicans)] had notably percentage growth. film, content, effectively preserves strawberries’ freshness, making it an ideal material.

Abstract Poly(butylene adipate‐ co ‐terephthalate) (PBAT) is popular because of its low cost, biodegradability, good processing properties, flexibility, and mechanical features. In this study, we explore the potential PBAT‐based bioplastics by adding AgVO 3 nanorods with PBAT to reduce costs. We produced nanocomposite films reinforced 1, 3, 5 wt% using solvent casting.
