“…Firmness and total soluble solids are important indicators for measuring fruit maturity and storage quality 43,44 . During storage, carbohydrates gradually decompose, and the state of water changes (starch is nearly completely converted into soluble sugar, and bound water in fruits is converted to free water).…”

Poly (lactic) acid-poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (PLA-PHB) blends were prepared through melting method and incorporated with α-tocopherol. The structural, thermal, mechanical and antioxidant properties of resulting active films were characterized, and its preservation effect on peaches (Prunus persica L.) was investigated. Results revealed that the glass transition temperature (T g) of PLA film was reduced from 53.2 C to 39.7 C after addition of plasticizer but increased again to 43.3 C after supplementation with α-tocopherol. PLA-PHB are polyesters with carboxylic groups that interacted with the hydroxide groups of α-tocopherol. Furthermore water vapour permeability, gas permeability and elongation at break were significantly improved, and 72.1% 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity was observed. PLA-PHB-α-tocopherol group revealed higher combined water and less oxidative spoilage through low-field nuclear magnetic resonance (LF-NMR) and effectively extended the shelf life of peach. Thus, the plasticized PLA-PHB-α-tocopherol film can be used as an active biodegradable packaging for fruits and vegetables.

Summary This study aimed to enhance the antioxidant property of biopolymer film without the incorporation of external agents. The active bilayer film with improved antioxidant activity has been developed by electrospinning zein, a prolamine of corn as nanofibre (average diameter of 286 nm) on solvent cast chitosan film. Zein nanofibres exhibited a slight increase in antioxidant activity as compared to solvent cast zein film. But, zein nanofibre coating on chitosan films significantly improved its antioxidant activity from 12.41% to 44.17%. The developed bilayer films were evaluated for its ability to prevent browning in minimally processed apple slices and compared with those of chitosan and zein films plasticised with polyethylene glycol. Higher surface to volume ratio and better affinity of zein nanofibres in the bilayer film helped enhance its anti‐browning ability. Thus, zein nanofibre‐coated chitosan bilayer films can be used as an effective anti‐browning packaging material for the packing of minimally processed fruits.

“…Considering that the permeability of the films might be influenced by parameters such as structure, morphology, and homogeneity of the matrix, scanning electron microscopy was used to investigate the microstructure of the films and the distribution of their components [ 50 ]. The morphology of MHF was irregular ( Figure 5 a).…”

Chitosan Film Containing Mansoa hirsuta Fraction for Wound Healing

et al. 2020

Chitosan films entrapped with the Mansoa hirsuta fraction (CMHF) was developed as a new dressing for wound care. The chromatographic profile of the M. hirsuta fraction (MHF) was evaluated by ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry, and the results showed that MHF is rich in acid triterpenes. Physicochemical characterization of the films prepared using the solvent casting method was performed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetry (TGA), differential scanning calorimetry (DCS), scanning electron microscopy (SEM), atomic force microscopy (AFM), and mechanical properties. CMHF exhibited characteristic bands of both chitosan and MHF, revealing a physical mixture of both. CMHF presented an amorphous nature, thermostability, and dispersion of MHF in the chitosan matrix, resulting in a rough structure. Incorporation of M. hirsuta fraction into chitosan matrix favorably enhanced the mechanical performance and films thickness. The in vivo wound treatment with CMHF for seven days showed a characteristic area of advanced healing, re-epithelization, cell proliferation, and collagen formation. Furthermore, wound closure reached 100% contraction after 10 days of treatment with modulation of interleukins. The incorporation of M. hirsuta fraction into chitosan films was advantageous and showed great potential for stimulating wound repair and regeneration.
