Antibacterial cellulose papers loaded with different isolated active compounds for food packaging applications

Bioactive Cellulose Nanopapers Impregnated with Cinnamon Essential Oil for Sustainable Antibacterial Packaging and Extended Shelf Life of Coriander Leaves

“…[ 60 ] According to de Oliveira et al., the surface unevenness is a consequence of cellulose surface rearrangement due to essential oil anchoring. [ 38 ] Microstructural voids were also discernible in the cross‐sectional view of CEO‐loaded films, aligning with findings by Noshirvani et al. [ 15 ] The presence of CEO exacerbated the intensity of these voids, as supported by the study on sodium alginate/carboxymethyl cellulose films incorporating cinnamon essential oil by Han et al.…”

“…A band spanning 1620-1647 cm −1 represented the bending vibration of chemically adsorbed water and the characteristic C = O stretching vibration of cinnamaldehyde. [38,39] The C-O-C pyranose ring structure within cellulose was reflected by a band ranging from 1010-1042 cm −1 showing a shift to higher wavenumbers with increased CEO content. Such shifts denote alterations in vibrational frequencies as a result of electron transfer and molecule deformation under applied frequencies affirming successful nanocellulose-CEO interactions.…”

“…The initial weight loss, occurring at ≈100-200 °C, is attributed to water molecules and minor essential oil component evaporation, aligned with findings by Bastos et al [45] The second degradation peak, ≈330 °C, signifies cellulose chain decomposition. [38] The final degradation peak beyond 400 °C corresponds to the volatilization of stable aromatic compounds present within the nanopaper. [4] Comparison of the onset degradation temperature (T 10 ), where 10% degradation transpires, reveals that lower CEO content lowers T 10 , while higher CEO levels lead to elevated T 10 compared to the control nanopaper.…”

Recent advances in biobased and biodegradable polymer nanocomposites, nanoparticles, and natural antioxidants for antibacterial and antioxidant food packaging applications

“…The application of cellulose and its derivatives has been a growing trend in the food industry because of its unique characteristics, structure, and properties (De Oliveira et al., 2021; Hu et al., 2021). In particular, CMC has gained prominence in recent years due to its suitable water solubility, gel‐forming capacity, nontoxicity, and biodegradability (Ezati et al., 2022; Sougandhi et al., 2021).…”

Preparation of PET‐EG‐β‐CD mat for the preservation of chilled pork

“…Particularly, eugenol (EG) was a very promising molecule with remarkable antioxidant and antimicrobial activities (Devi et al, 2010). Oliveira et al (2021) produced active cellulose-based paper, chemically and mechanically treated the pre-prepared active cellulosebased paper, and introduced EG through microwave to successfully produce paper with significant antimicrobial effect. The antimicrobial mechanism of EG may be related to its ability to increase the permeability of cell membrane, causing the leakage of bacterial proteins, ATP and DNA (Cui et al, 2018).…”
