“…Most of the plant extracts resulted in an increase in the film thickness, potentially attributed to a greater concentration of solids incorporated within the film structure (Kola, 2020). Several plant extracts incorporated films based studies showed the similar findings (Riaz et al, 2020;Yuan et al, 2020;Zhang, Lian, et al, 2020).…”

Boswellia sacra and its derivatives exhibit notable bioactive properties, which have been the subject of extensive scientific research; however, their potential applications in food packaging remain largely untapped. In the current study, cellulose, sodium alginate, and gelatin composite edible films were fabricated with the addition of different concentrations (0.2% and 0.3%) of the ethanolic fraction of Boswellia sacra oleo gum resin (BSOR). The resultant films were examined for their physical, chemical, mechanical, barrier, optical, and antioxidant properties. Moreover, the films were characterized using Scanning Electron Microscopy (SEM), X‐ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) to study the impact of incorporating BSOR on the morphological, crystalline, and chemical properties of the films. The addition of BSOR increased the film thickness (0.026–0.08 mm), water vapor permeability (0.210–0.619 (g.mm)/(m2.h.kPa), and the intensity of the yellow color (3.01–7.20) while reducing the values of both tensile strength (6.67–1.03 MPa) and elongation at break (83.50%–48.81%). SEM and FTIR analysis confirmed the interaction between the BSOR and film‐forming components. The antioxidant properties of the edible films were significantly increased with the addition of BSOR. The comprehensive findings of the study demonstrated that BSOR possesses the potential to serve as an efficient natural antioxidant agent in the fabrication of edible films.

“…It is worth noting that all of the composite lms show an amorphous pattern similar to the starch lm at 2θ≥25°. The diffraction peak intensity of the CS/кC -GSE lms was more substantial than the starch lms, and the crystalline properties of the polyphenol-rich CS/кC lms are in uenced by the content and composition of the polyphenols in the extract (Yuan et al, 2019). Similarly, Gao et al (2021) found a similar effect with the addition of black soy bark ethanol extract to corn starch.…”

A biodegradable packaging film with antioxidant and antibacterial activity was developed by adding grape seed ethanol extract (1%、3%、5% per g of starch) to corn starch/κ-carrageenan (CS/кC) complex film made using the solvent casting method. The κ-carrageenan is a promising film-forming polymer with highly elastic and adhesive properties. The addition of GSE enhanced the water vapor permeability, break elongation, and opacity of the film, and this is related to the excellent dispersion of GSE in CS/кC film observed by scanning electron microscope, and the formation of intermolecular hydrogen bond between GSE and CS proved by FT-IR. Thermogravimetric analysis showed that the CS/кC -5% GSE film has a high glass transition temperature (121.65℃). With the increase of GSE content, it improved the antioxidant capacity (DPPH radical scavenging 26.5% and ABTS radical scavenging 45.0%) and antibacterial activity (Bacteriostatic circle diameter of E. coli 12.78 ± 0.42 mm and S. aureus strains 13.52 ± 0.66 mm) of CS/кC films. Simulated food packaging experiments presented that CS/кC-GSE film significantly reduced the peroxide value of lard (P < 0.05). The above results indicate that the GSE can be used as a food-grade packaging material and has a good application prospect in the food industry.
