“…Pellá et al [ 23 ] found that coating guava fruit with cassava starch, casein, and gelatin blends increased its shelf life by two days due to the low water vapor transmission rate of the films, which decreased the fruits’ mass loss. Kowalczyk et al [ 24 ] developed edible films based on pullulan/gelatin blends incorporated with potassium sorbate that increased the pH, UVB-barrier capacity, and moisture absorption properties.…”

Edible and active packaging are attractive for use in food packaging applications due to their functionality and sustainability. This research developed new antioxidant active food packaging materials from cassava starch/gelatin (7:3 w/w) composite films with varied antioxidant types (quercetin and tertiary butylhydroquinone (TBHQ)) and concentrations (0–200 mg/200 mL film-forming solution) and evaluated their properties. Antioxidant addition altered the mechanical and barrier properties of the films. At 34% relative humidity (RH), increasing the concentration of quercetin increased the tensile strength and decreased the elongation at break of the composite films. Increasing quercetin and TBHQ contents increased the film water solubility and water vapor transmission rate. Intermolecular interactions between the antioxidants and films, as found in Fourier transform infrared (FT-IR) spectra and XRD micrographs, were related to the changed film functionalities. In food application studies, the cassava starch/gelatin films containing quercetin and TBHQ retarded the oxidation of lard (more than 35 days) and delayed the redness discoloration of pork. Cassava starch/gelatin composite films integrated with quercetin and TBHQ can be utilized as active packaging that delays oxidation in foods.

“…The analyses of the optical parameters (yellowness indexes (YI), light transmission (T%), and opacity (Op)), moisture content (MC), water vapor permeability (WVP), and mechanical properties (tensile strength (TS), elongation at break (E), and elastic modulus (EM)) were performed as described previously (Kowalczyk et al, 2020c, Kowalczyk et al, 2021b, Kowalczyk et al, 2021c. Additionally, the increase in the lm mass (WV gain, %) during the WVP analysis was determined.…”

The properties of gelatin (GEL) and whey protein isolate (WPI) edible films incorporated with fireweed extract (FE, 0-0.05%) were compared. The GEL films had more crystalline structure, thus were mechanically stronger and less permeable to water vapor than the WPI films. Furthermore, GEL offered more transparent, less yellow, and more stretchable films. In turn, the WPI films had superior UV-protective potential. An increase in the FE concentration yielded films with improved UV-blocking ability. The WPI films incorporated with higher levels of FE (0.025–0.05%) exhibited better antiradical potential in comparison to the GEL films. This result indirectly indicates that the WPI-based films, being more soluble and less swellable, ensured faster release of FE than the GEL films. The slower building up of the antiradical activity of the FE-supplemented GEL films suggests that GEL could be more useful in the development of slow/less migratory active packaging systems for high moisture food.

“…On the other hand, DSC thermograms of pullulan NM and pullulan/ γCD NM, respectively, displayed endothermic peaks at ∼82 and ∼88 °C based on the dehydration of water (Figure S4). 61,62 It is clear that the incorporation of γCD in pullulan NM leaded to a shift at the dehydration temperature to a higher temperature. Additionally, the peak area representing the ΔH value and corresponding to the energy required for the thermal transition increased from 263 to 350 J/g with the addition of γCD (Figure S4A).…”

There is an ongoing rise in global plastic waste because of the mass production and vast consumption of surgical face masks during the COVID-19 outbreak. This problem leads to a crucial need for alternative face coverings which can eliminate environmental concerns. Using cloth masks can be a sustainable solution if combined with a functional filtering layer. In this study, electrospun nanofibrous mats (NM) were generated using a renewable biopolymer; pullulan by the incorporation of cyclodextrin inclusion complexes (γCD-IC) of naturally occurring essential oil compound; trans-cinnamaldehyde (CAH). Pullulan/CAH-γCD-IC NM was readily inserted into a cloth mask due to its free-standing and foldable features and achieved higher loading efficiency (∼62%) than pullulan/CAH NM (∼10%). Here, pullulan/CAH-γCD-IC NM showed substantial and better antibacterial activity, long-term storage stability, and thermal stability due to inclusion complexation. Pullulan/ CAH-γCD-IC NM was also obtained with promising properties of pore size (∼390 nm) and water vapor permeability (∼890 g/m 2 /day). The water solubility of pullulan/CAH-γCD-IC NM ensured fast and easy disposal without potential environmental loading, thanks to the biocompatibility of components. Briefly, pullulan/CAH-γCD-IC NM can create an attractive alternative as a functional layer that can be combined with the cloth mask.
