“…It was found that the moisture content was diminished by the addition of TiO2 in the CST film, which could be explained by the hydrogen bonds between TiO2 nanoparticles and matrix reduced the hydrophilic sites in starch, limiting the interaction among the starch and moisture [15]. Whereas, the enhanced moisture content of the CSRE and CSTRE film were mainly owing to the hydrophilicity of RE [16].…”

“…As presented in Table 1, the films were evidently thickened as the incorporation of TiO2 nanoparticles and RE had negligible impact on the film thickness. It could be related to the addition of TiO2 enhanced solid mass in the film's network, with the aggregation of small nanoparticles in the starch matrix, which promoted the film thickness [15].…”

The biodegradable and multifunctional nanocomposite films incorporated with TiO2 nanoparticles (T) and roselle extract (RE) in corn starch (CS) matrix were successfully developed by the solution casting method. The physical and functional properties of bionanocomposite films were comparatively evaluated as well as an analysis of the microstructure of films. The properties of CS film could be significantly altered by incorporating TiO2 and/or RE, and the CSRE, CST and CSTRE films all exhibited improved mechanical properties, higher barrier properties against water vapor and UV light. The composite films containing RE also obtained pH sensitive ability, showing color visibly variations to different pH values. The CSTRE film performance 1.52 times higher tensile strength and 27.1% lower water vapor permeability than CS film accompanying enhanced UV light blocking capacity. Scanning electron microscopy (SEM) appeared more compact and homogeneous microstructure in CSRE and CSTRE films compared to CS film and the Fourier transform infrared (FTIR) spectroscopy and X ray diffraction (XRD) results indicated that there were good interactions between TiO2 nanoparticles, RE and starch molecules. Antioxidant and antimicrobial assays revealed that the antioxidant activity of bionanocomposite films were mainly affected by RE and the antimicrobial impression related to both RE and TiO2. The CSTRE film possessed strong antioxidant activity and exhibited obvious antimicrobial activity against S. aureus and E. coli. It suggested that the multifunctional bionanocomposite films incorporated TiO2 nanoparticles and RE with corn starch could be a potential approach for developing sustainable active food packaging.

“…e peaks between 850 and 1200 cm −1 link with glucose pyranose and C-O vibrations stretching glucose units, coupling bonds (-C-O and C-C) stretching, respectively [23,24]. e peaks noticed within a range of 850-1450 cm −1 represent C-OH stretching vibration and O-H bond vibration [25,26]. As ME and GA were incorporated, the positions of peaks slightly altered and shifted to lower wave numbers, possibly due to some interaction among active lm components (MS, GA, and ME) [27].…”

Moth bean starch (MS), gelatin (GA), and Murraya koenigii leaves extract (ME) are blended at different compositions to prepare film and coating according to casting and dipping approaches. Different MS, GA, and ME compositions were used to synthesize films and coating. The film compositions (MS : GA: ME: 60 : 20 : 20 and MS : GA: ME:20 : 60 : 20) were represented in terms of F3 and F4, respectively. The results showed that F3 exhibited better physicochemical properties than other films. In addition, SEM images showed that all components of the films were uniformly mixed and formed smooth surface morphology without cracks and bubbles. FTIR results indicate that ME in the films induces interactions between the film components, causing an improvement in compactness. Moreover, an optimized film-forming solution was tested as a coating. Parameters such as skin tightness, weight loss, pH, titratable acidity, and sensory analysis were considered to check the quality of coated Solanum melongena during storage. The results show that the formulation effectively maintains the quality parameters during storage. Furthermore, it also notices that coating extends the shelf life of Solanum melongena by one week.

“…Food packaging films protect food from microbial contamination during storage and reduce the risk of foodborne illnesses, such as food poisoning, from consuming contaminated foods. [1,2] These films also preserve the food's quality and increase the food's shelf life. [3] For instance, antimicrobial food packaging films can inhibit the growth of microorganisms by releasing bioactive chemicals in a regulated manner.…”

Edible films can be used for food packaging to extend the shelf life of foods and protect them from exposure to moisture, microorganisms, pathogens, and bacteria. In the present study, the effect of plasticization and cross‐linking, which are modification approaches for upgrading the properties of starch, are investigated. Glycerol and sorbitol are used as plasticizing agents, and succinic acid is used as a cross‐linking agent. The results demonstrate that the addition of glycerol and sorbitol to the film‐forming solutions reduces brittleness and increases peeling ability and flexibility upon drying. Furthermore, the film matrix supports improvements in water vapor permeability (WVP), swelling index (SI), and mechanical properties. The glycerol‐based finger millet starch (FMS) films exhibits better thermal stability than the sorbitol‐based FMS film. The microscopic images of the films show that the use of glycerol in the film improves compactness and homogeneity compared to sorbitol‐based FMS films.
