“…Kavoosi et al [46] reported a decrease in WVP after Zataria multiflora essential oil was added to gelatin films. Nunes et al [47] also reported a decrease in water vapor permeability and tensile strength after lemon essential oil was added to gelatin matrices. Also, the nanoemulsion particle size influences the WVP results.…”

The concern about consuming eco-friendly products has motivated research in the development of new materials. Therefore, films based on natural polymers have been used to replace traditional polymers. This study consists of a production of films based on gelatin reinforced with black pepper essential oil-loaded nanoemulsions and Cloisite Na+. The films were characterized by water vapor permeability, mechanical and thermal properties, surface contact angle, X-ray diffraction and scanning electron microscopy. It was observed that the films containing the nanoemulsion have higher permeability values and an increase in their mechanical resistance. The addition of nanoclay contributed to an increase in the surface hydrophobicity of the film and an increase in the tensile strength, at break, by about 150%. The addition of essential oil nanoemulsions led to an increase in thermal stability. The presence of clay dispersion contributed to the formation of a surface that was slightly rougher and grainier. The addition of the black pepper essential oil nanoemulsion resulted in an increase in porosity of the gelatin matrix. Through X-ray diffraction analysis, it was possible to conclude that both the polymeric gelatin matrix and the essential oils nanoemulsion are intercalated with the clay dispersion.

“…Also, this could be related to the replacement of strong polymer–polymer interactions between calcium caseinate and gelatin by the weaker polymer–oil interactions in the composite film matrix. A previous study showed that TS was reduced after adding lemon oil to gelatin films (Nunes et al ., 2018). However, another study also showed a significant increase in TS due to the addition of EO in chitosan films (Ojagh et al ., 2010).…”

SummaryThis research focuses on the development and assessment of films composed of gelatin (GE) and calcium caseinate (CC), loaded with varying concentrations of petitgrain essential oil (PEO). A comprehensive assessment of the resulting films was conducted with a focus on the antioxidant, antibacterial, and physicochemical attributes. GCMS analysis identified the primary constituents of PEO, including linalyl acetate, linalool, α‐pinene, α‐terpineol, limonene, β‐myrcene, geranyl acetate, and neryl acetate. The antioxidant capacity of GE‐CC films increased significantly with increasing PEO concentration, as evidenced by DPPH and ABTS assays. Simultaneously, increased PEO concentration led to increased thickness, water vapour permeability (WVP), elongation at break (EAB), and water solubility (WS) in the active films while reducing moisture content (MC) and tensile strength (TS). In terms of optical characteristics, the transparency of the films decreased, while the b* (yellowness) and ΔE (total colour variation) values increased upon oil incorporation. The presence of intermolecular interactions between the polymers and the oil was confirmed through FTIR and morphological characteristics studied by SEM. The addition of PEO to the films resulted in improved thermal resistance against degradation, as observed in the thermo‐gravimetric analysis (TGA). Moreover, these active films showed potent antimicrobial activity against C. albicans and P. aeruginosa. In summary, this study underscores the suitability of GE‐CC films containing PEO for food packaging purposes, highlighting their functional characteristics and environmentally friendly nature.
