    A Comparative Study of the Properties of Gelatin (Porcine and Bovine)-Based Edible Films Loaded with Spearmint Essential Oil
    (Mdpi, 2023) Bhatia, Saurabh; Al-Harrasi, Ahmed; Jawad, Muhammad; Shah, Yasir Abbas; Al-Azri, Mohammed Said; Ullah, Sana; Anwer, Md Khalid
    Gelatin (bovine/porcine)-based edible films are considered as an excellent carrier for essential oils (EOs) to preserve food quality and extend their shelf life. Spearmint essential oil (SEO) is known for its potential antioxidant and antimicrobial effects; nevertheless, its food applications are limited due to the volatile nature of its active components. Thus, edible films loaded with essential oil can be an alternative to synthetic preservatives to improve their food applications. In the present study, the effect of SEO addition was investigated on the physicochemical properties of bovine and porcine gelatin films, and antioxidant activity was assessed. GCMS (Gas chromatography mass spectrometry) analysis revealed the presence of carvone (55%) and limonene (25.3%) as major components. The incorporation of SEO into the films decreased the opacity, moisture content, water solubility, and elongation at break of bovine and porcine gelatin films. However, with the addition of EO, the thickness and water vapor permeability of bovine and porcine-based gelatin films increased. Moreover, the addition of SEO increased the tensile strength (TS) of the porcine-based film, whereas bovine samples demonstrated a decrease in tensile strength. XRD (X-ray diffraction) findings revealed a decrease in the percentage crystallinity of both types of gelatin films. SEM (scanning electron microscope) results showed the changes in the morphology of films after the addition of SEO. Antioxidant properties significantly (p < 0.05) increased with the incorporation of EO when compared with control films. Therefore, the addition of SEO to gelatin-based edible films could be an effective approach to prepare an active food packaging material to prevent food oxidation.

    (Wiley, 2024) Bhatia, Saurabh; Shah, Yasir Abbas; Al-Harrasi, Ahmed; Ullah, Sana; Anwer, Md Khalid; Koca, Esra; Aydemir, Levent Yurdaer
    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)/(m(2).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.

    Fabrication, characterization and antioxidant activities of pectin and gelatin based edible film loaded with Citrus reticulata L. essential oil
    (Wiley, 2024) Bhatia, Saurabh; Al-Harrasi, Ahmed; Ullah, Sana; Shah, Yasir Abbas; Al-Azri, Mohammed Said; Jawad, Muhammad; Anwer, Md Khalid
    In the present work, pectin and gelatin-based edible films (EFs) loaded with Citrus reticulata L. (tangerine) essential oil were fabricated and evaluated for their potential application in food packaging. GC-MS analysis and physiochemical, mechanical, and antioxidant analysis of the synthesized edible films and oil extract were carried out. GC-MS analysis of the tangerine essential oil revealed the presence of around 40 different chemical constituents, and among them, limonene (43.85%), linalyl acetate (19.16%), linalool (18.38%), and beta-Myrcene (3.41%) were found as the major constituent. Fourier transform infrared spectroscopy showed the interaction between the functional groups of the film components. Mechanical parameter assessment showed that the tensile strength of the edible film increases and elongation at break values decreases with oil addition. The thickness of the EFs increased with oil addition, while water solubility, water vapor permeability, and transparency decreased. In antioxidant potential assessment assays, maximum activity (DPPH center dot and ABTS(center dot+) reducing potential) was reported for edible film samples containing a maximum amount (60 mu L) of tangerine oil. We found that pectin and gelatin-based edible films loaded with tangerine essential oil exhibit better characteristics and could be used as a food packaging material.

    Physical, Chemical, Barrier, and Antioxidant Properties of Pectin/Collagen Hydrogel-Based Films Enriched with Melissa officinalis
    (Mdpi, 2023) Bhatia, Saurabh; Al-Harrasi, Ahmed; Alhadhrami, Aysha Salim; Shah, Yasir Abbas; Kotta, Sabna; Iqbal, Javed; Anwer, Md Khalid
    The essential oil extracted from Melissa officinalis (MOEO) exhibits a wide range of therapeutic properties, including antioxidant, antibacterial, and antifungal activities. The current research aimed to analyze the mechanical, barrier, chemical, and antioxidant properties of pectin and collagen-based films. Hydrogel-based films loaded with varying concentrations of MOEO (0.1%, 0.15%, and 0.2%) were prepared by solvent-casting method, and their physicochemical as well as antioxidant properties were examined. GC-MS analysis revealed the presence of major components in MOEO such as 2,6-octadienal, 3,7-dimethyl, citral, caryophyllene, geranyl acetate, caryophyllene oxide, citronellal, and linalool. Fourier transform infrared (FTIR) results revealed the interaction between components of the essential oil and polymer matrix. Scanning electron microscopy (SEM) revealed that films loaded with the highest concentration (0.2%) of MOEO showed more homogeneous structure with fewer particles, cracks, and pores as compared to control film sample. MOEO-incorporated films exhibited higher elongation at break (EAB) (30.24-36.29%) and thickness (0.068-0.073 mm); however, they displayed lower tensile strength (TS) (3.48-1.25 MPa) and transparency (87.30-82.80%). MOEO-loaded films demonstrated superior barrier properties against water vapors. According to the results, the incorporation of MOEO into pectin-collagen composite hydrogel-based films resulted in higher antioxidant properties, indicating that MOEO has the potential to be used in active food packaging material for potential applications.

    Physicochemical Characterization and Antioxidant Properties of Chitosan and Sodium Alginate Based Films Incorporated with Ficus Extract
    (Mdpi, 2023) Bhatia, Saurabh; Al-Harrasi, Ahmed; Shah, Yasir Abbas; Jawad, Muhammad; Al-Azri, Mohammed Said; Ullah, Sana; Anwer, Md Khalid
    Aqueous extract of fruit obtained from Ficus racemosa enriched with phenolic components was used for the first time to fabricate chitosan (CS) and sodium alginate (SA)-based edible films. The edible films supplemented with Ficus fruit aqueous extract (FFE) were characterized physiochemically (using Fourier transform infrared spectroscopy (FT-IR), Texture analyser (TA), Thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction (XRD), and colourimeter) and biologically (using antioxidant assays). CS-SA-FFA films showed high thermal stability and high antioxidant properties. The addition of FFA into CS-SA film decreased transparency, crystallinity, tensile strength (TS), and water vapour permeability (WVP) but ameliorate moisture content (MC), elongation at break (EAB) and film thickness. The overall increase in thermal stability and antioxidant property of CS-SA-FFA films demonstrated that FFA could be alternatively used as a potent natural plant-based extract for the development of food packaging material with improved physicochemical and antioxidant properties.

    The Effect of Sage (Salvia sclarea) Essential Oil on the Physiochemical and Antioxidant Properties of Sodium Alginate and Casein-Based Composite Edible Films
    (Mdpi, 2023) Bhatia, Saurabh; Al-Harrasi, Ahmed; Shah, Yasir Abbas; Jawad, Muhammad; Al-Azri, Mohammed Said; Ullah, Sana; Anwer, Md Khalid
    The aim of this study was to examine the effect of Sage (Salvia sclarea) essential oil (SEO) on the physiochemical and antioxidant properties of sodium alginate (SA) and casein (CA) based films. Thermal, mechanical, optical, structural, chemical, crystalline, and barrier properties were examined using TGA, texture analyzer, colorimeter, SEM, FTIR, and XRD. Chemical compounds of the SEO were identified via GC-MS, the most important of which were linalyl acetate (43.32%) and linalool (28.51%). The results showed that incorporating SEO caused a significant decrease in tensile strength (1.022-0.140 Mpa), elongation at break (28.2-14.6%), moisture content (25.04-14.7%) and transparency (86.1-56.2%); however, WVP (0.427-0.667 x 10(-12) g center dot cm/cm(2)center dot s center dot Pa) increased. SEM analysis showed that the incorporation of SEO increased the homogeneousness of films. TGA analysis showed that SEO-loaded films showed better thermal stability than others. FTIR analysis revealed the compatibility between the components of the films. Furthermore, increasing the concentration of SEO increased the antioxidant activity of the films. Thus, the present film shows a potential application in the food packaging industry.
