Preparation of Carrageenan-based Antimicrobial Films Incorporated With Sulfur Nanoparticles

Carrageenan-Based Antimicrobial Films Integrated with Sulfur-Coated Iron Oxide Nanoparticles (Fe3O4@SNP)

“…More potent antimicrobial activity of SNPs against L. monocytogenes was reported earlier. 24,59 On the other hand, E. coli is a mesophilic bacterium and generally grows at higher temperatures (>25 °C). The Carr/SNP films, hence, were not much effective against this bacterial strain.…”

“…14,19 Sulfur nanoparticles (SNPs) have been produced using a variety of sulfur-containing materials such as hydrogen sulfide, 22 sodium thiosulfate, 16 sodium polysulfide, 23 and elemental sulfur. 13 SNPs have been employed for the fabrication of functional carrageenan-based food packaging materials 24 and wound-dressing hydrogels 25 due to the potent antibacterial activity with low cytotoxicity of SNPs. 16 In our previous study, two different types of SNPs were synthesized from sodium thiosulfate and elemental sulfur and used to prepare carrageenan/SNP nanocomposite films.…”

“…In recent years, nano-sized sulfur particles have been used not only for the production of nanocomposite films but also in various fields such as agrochemical industries, synthesis of nanocomposites for lithium-ion batteries, and biomedical applications as antibacterial agents and anticancer compounds. , Sulfur nanoparticles (SNPs) have been produced using a variety of sulfur-containing materials such as hydrogen sulfide, sodium thiosulfate, sodium polysulfide, and elemental sulfur .

Carrageenan functional film integrated with Pickering Emulsion of Oregano Oil Stabilized by Cationic Nanocellulose for Active Packaging

“…One innovative packaging technology, biopolymer-based active packaging, is a sustainable and environmentally friendly technique to extend the shelf life of food without sacrificing food safety and quality (Roy and Rhim, 2021). Functional packaging materials based on biopolymers have emerged due to impressive characteristics, such as abundant availability, renewability, biodegradability, biocompatibility, and the potential for developing novel functional composite materials (Saedi et al, 2020).…”

“…Natural material such as chitosan, starch, pectin, and cellulose are being used to manufacture packaging materials in the present active packaging development trend (Wu et al, 2021). As one of such biopolymers, carrageenan has been widely used to prepare functional packaging films due to its excellent film-forming property with high mechanical strength (Saedi et al, 2020). Carrageenan is a group of sulfated polysaccharides made up of a repeating disaccharide unit of sulfated galactose and anhydrous-galactose connected via α-1,3 and β-1,4 glycosidic linkages.…”
