“…Demand for innovative and improved biodegradable packaging has rapidly increased over the years [1] due to consumer awareness and concerns about food safety [2,3], limited resources [4], and environmental impacts [5,6]. The biocompatible [7], biodegradable [8], nontoxic, and sustainable [9] packaging materials are especially attractive for further development to address these concerns [2,10]. As a result, the development of active packaging materials has moved toward the adoption of natural active ingredients [11][12][13].…”

The effects of green tea extract (GTE) at varying concentrations (0.000, 0.125, 0.250, 0.500, and 1.000%, w/v) on the properties of rice-starch-pectin (RS-P) blend films were investigated. The results showed that GTE addition enhanced (p < 0.05) the antioxidation properties (i.e., total phenolic content, DPPH radical scavenging activity, and ferric reducing antioxidant power) and thickness of the RS-P composite film. The darker appearance of the RS-T-GTE blend films was obtained in correspondence to the lower L* values. However, the a* and b* values were higher toward red and yellow as GTE increased. Though GTE did not significantly alter the film solubility, the moisture content and the water vapor permeability (WVP) of the resulting films were reduced. In addition, the GTE enrichment diminished the light transmission in the UV-Visible region (200–800 nm) and the transparency of the developed films. The inclusion of GTE also significantly (p < 0.05) lowered the tensile strength (TS) and elongation at break (EAB) of the developed film. The FT-IR spectra revealed the interactions between RS-P films and GTE with no changes in functional groups. The antimicrobial activity against Staphylococcus aureus (TISTR 764) was observed in the RS-P biocomposite film with 1% (w/v) GTE. These results suggested that the RS-P-GTE composite film has considerable potential for application as active food packaging.

“…Currently, various bio-based polymers such as polysaccharides and proteins are being studied. Although they have disadvantages such as low strength and gas barrier properties, they attract great attention as substitutes for petroleum-based plastics [12][13][14]. Another way to address the limitations of bio-based polymer matrices is to combine biopolymers to create blend films or to create composite materials with functional nanofillers or bioactive compounds [15][16][17][18][19].…”

Pullulan/chitosan-based multifunctional edible composite films were fabricated by reinforcing mushroom-mediated zinc oxide nanoparticles (ZnONPs) and propolis. The ZnONPs were synthesized using enoki mushroom extract and characterized using physicochemical methods. The mushroom-mediated ZnONPs showed an irregular shape with an average size of 26.7 ± 8.9 nm. The combined incorporation of ZnONPs and propolis pointedly improved the composite film’s UV-blocking property without losing transparency. The reinforcement with ZnONPs and propolis improved the mechanical strength of the pullulan/chitosan-based film by ~25%. Additionally, the water vapor barrier property and hydrophobicity of the film were slightly increased. In addition, the pullulan/chitosan-based biocomposite film exhibited good antioxidant activity due to the propolis and excellent antibacterial activity against foodborne pathogens due to the ZnONPs. The developed edible pullulan/chitosan-based film was used for pork belly packaging, and the peroxide value and total number of aerobic microorganisms were significantly reduced in meat wrapped with the pullulan/chitosan/ZnONPs/propolis film.

“…The advances in petrochemical industry have led to the exploitation of fossil and non-renewable sources in production of poor biodegradation wrapping films with chemical residues in food products and significant effects on human health and the environment. This fact led to the increasing attention for biodegradable alternatives to reduce environmental problems and supporting the trend towards sustainability and environment-friendly natural biopolymer [1,2]. Consequently, the researchers have tended to produce biomultifunctional films of natural polymers as substitutes for synthetic plastic, such as polyvinyl dichloride, low-density polyethylene and polyvinyl chloride due to nontoxic, biodegradable and renewable nature [3,4].…”

Production of Bio-composite Films from Gum Arabic and Galangal Extract to Prolong the Shelf Life of Agaricus bisporus

The current study was performed to develop biodegradable films with matrix composed from gum Arabic (GA) and different concentrations from Alpinia officinarum phenolic extract (AOE). The color indices, physical properties, surface shape, crystallinity, mechanical properties and thermal stability of produced films were investigated. The incorporation of AOE extract (0.25 g/100 mL) inside GA films increased dark yellow color, reduced moisture, swelling, solubility and water vapor permeability (WVP) of films up to 10.29%, 21.05%, 14.15% and 4.20 × 10−10 g H2O/m s p.a., respectively. Furthermore, the scanning electron micrographs showed uniform structure with rough surface and turmoil spots in the structure by increasing AOE concentration inside films. The FT-IR analysis showed typically bands that proved physical interaction between AOE extract and GA polymer. The fabricated films showed satisfied thermal stability manners with declining trend by incorporation of AOE inside GA films. Furthermore, the developed films showed significant effects on reducing the changes of browning index from 17.20 to 24.54 and firmness from 33.98 to 22.65 N of Agaricus bisporus caps during storage days compared with commercial packaging materials.
