[PMID: 37913706 DOI: 10.1016/j.foodchem.2023.137710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 10/06/2023] [Accepted: 10/08/2023] [Indexed: 11/03/2023]
Abstract
The development of novel eco-friendly materials like chitosan for food storage and preservation has become crucial in eliminating plastic packaging and minimizing waste. In this work, cinnamaldehyde has been encapsulated in chitosan nanoparticles and subsequently incorporated into a 2 % chitosan film. The obtained nanoparticles achieved an average radius size of 89.80 nm, PDI of 0.40, and spherical morphology determined by SEM. Cinnamaldehyde was encapsulated in chitosan nanoparticles achieving values of encapsulation close to 7 %, showing a biphasic release profile with sustained release during 5 days. Films with an average thickness of 0.124 mm and elongation at break of 63.66 % to 76.50 % were obtained. Finally, the antimicrobial properties of the films was tested showing reduction values in total aerobic value of 4.85 log cfu/g, total coliform of 1.26 log cfu/g and grow potential value of < 0.5 log10 for Listeria monocitogenes over 20 days.

[PMID: 38061305 DOI: 10.1016/j.meatsci.2023.109401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 10/21/2023] [Accepted: 11/28/2023] [Indexed: 01/13/2024]
Abstract
The study investigated the antioxidant effect on lipid and protein oxidation, microbial count and other physicochemical attributes of meat patties packaged in flaxseed gum (FSG) based films added with betel leaf extract (BLE) during refrigerated storage (4 ± 1 °C) of 30 days. FSG films were developed after incorporating 0, 2.5, 5, 7.5 and 10% of BLE (BLE0, BLE1, BLE2, BLE3 and BLE4) respectively. The patties showed no change in pH due to composite films however, a remarkable effect in retarding the weight loss and color change along with an improvement in sensory score and microbial quality. TBARS of the patties packed in treated films ranged from 0.10 to 0.99 (mg MDA/kg), lower than that of the control 0.34-1.33 (mg MDA/kg). The BLE4 (packed in FSG film with 10% BLE) had the lowest metmyoglobin content of 31.71% compared to the control sample (69.02%) on 30th day of refrigerated storage. Further, a significant reduction in moisture and color change was observed in meat patties packed in FSG-BLE composite films compared to the control patties. Hence, this study concluded that the FSG-BLE composite films improves the storage stability by impeding the rate of lipid oxidation indicating the developed film's promising potential as a sustainable material in active packaging for the shelf life extension of high-fat meat products and other perishable food products.

Abstract
Chitosan films enriched with aqueous nettle extract (Urtica dioica L.) were evaluated by measuring their solubility, equilibrium moisture, water vapor permeability, spectral and antioxidant properties, and microstructure. Nettle extract showed a significant effect on the analyzed film properties. The addition of nettle extract manifested a sharp decrease in water vapor permeability, decreasing from 5.64 · 10-11 to 2.22 · 10-11 g/m·s·Pa. The chitosan- nettle extract films exhibited a high free-radical scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Incorporation of nettle extract into the chitosan matrix was successfully carried out to obtain antioxidant films. The results obtained showed that the incorporation of nettle extract allowed obtaining chitosan films with antioxidant properties, including a total phenolic content up to 1.57 mg GAE/g film. Furthermore, the films with nettle extract boast an UV shielding ability with transmittance values close to zero in the UV region and a water solubility up to 1 %. The inherent biodegradability is also a strong advantage of the developed active films.

Abstract
There has been a shift from use of petroleum-based plastics, causing serious environmental pollution, towards innovative and biodegradable edible packaging. The present study documents the development of composite edible films based on the flaxseed gum (FSG) modified by the incorporation of betel leaf extract (BLE). The films were assessed for physicochemical, mechanical, morphological, thermal, antimicrobial and structural characteristics. Scanning electron microscopy images indicated that the roughness decreased with an increase in BLE concentration. The water vapor permeability of the FSG-BLE films ranged from 4.68 to 1.59 × 10-9 g s- 1 m- 2 Pa- 1, lower than that of the control sample (6.77 × 10-9 g s- 1 m- 2 Pa- 1). The BLE4 (containing 10 % BLE) films had the highest tensile strength of 32.46 MPa compared to the control sample (21.23 MPa). Similarly, EAB and seal strength of the films incorporated with BLE were ameliorated. X-ray diffraction pattern and FTIR illustrated the shift of amorphous to crystalline behavior and a significant interaction among the BLE and FSG functional groups. Furthermore, the thermal stability of the treated films was not affected significantly however, they showed improved antimicrobial activity with the highest diameter of inhibition zone in the BLE4 sample. This study concluded that the FSG-BLE composite films (BLE4 in particular) can be considered as novel packaging material for food conservation coupled with a potential to enhance the shelf life of perishable food products.

Evaluation of Physically and/or Chemically Modified Chitosan Hydrogels for Proficient Release of Insoluble Nystatin in Simulated Fluids. Gels 2022; 8:gels8080495. [PMID: 36005096 PMCID: PMC9407202 DOI: 10.3390/gels8080495] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 08/06/2022] [Accepted: 08/08/2022] [Indexed: 11/17/2022] Open
Abstract
To avoid fungal spreading in the bloodstream and internal organs, many research efforts concentrate on finding appropriate candidiasis treatment from the initial stage. This paper proposes chitosan-based physically or chemically cross-linked hydrogels aimed to provide sustained release of micronized nystatin (NYSm) antifungal drug, known for its large activity spectrum. Nystatin was demonstrated itself to provide hydrodynamic/mechanic stability to the chitosan hydrogel through hydrophobic interactions and H-bonds. For chemical cross-linking of the succinylated chitosan, a non-toxic diepoxy-functionalized siloxane compound was used. The chemical structure and composition of the hydrogels, also their morphology, were evidenced by infrared spectroscopy (FTIR), by energy dispersive X-ray (EDX) analysis and by scanning electron microscopy (SEM), respectively. The hydrogels presented mechanical properties which mimic those of the soft tissues (elastic moduli < 1 MPa), necessary to ensure matrix accommodation and bioadhesion. Maximum swelling capacities were reached by the hydrogels with higher succinic anhydride content at both pH 7.4 (429%) and pH 4.2 (471%), while higher amounts of nystatin released in the simulative immersion media (57% in acidic pH and 51% in pH 7.4) occurred from the physical cross-linked hydrogel. The release mechanism by non-swellable matrix diffusion and the susceptibility of three Candida strains make all the hydrogel formulations effective for NYSm local delivery and for combating fungal infections.
