    Myrrh Oleo-Gum Resin as a Functional Additive in Pectin and ?-Carrageenan Composite Films for Food Packaging
    (Wiley, 2024) Shah, Yasir Abbas; Bhatia, Saurabh; Chinnam, Sampath; Al-Harrasi, Ahmed; Tarahi, Mohammad; Khan, Talha Shireen; Alam, Tanveer
    Myrrh oleo-gum-resin (MOGR) is a natural substance that has a rich history of medicinal use due to its anti-inflammatory, antimicrobial, and antioxidant properties. The present study reports on the fabrication and assessment of pectin and K-carrageenan composite films infused with varying proportions (0.3%, 0.5%, and 0.7%) of MOGR. Morphological analysis of the film samples was conducted using Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). The results indicated that the introduction of MOGR led to a notable increase in surface roughness. The SEM micrographs of the films showed that the MOGR addition had an important effect on the microstructure of the film. The surface hydrophobicity of the MOGR-loaded films increased, as confirmed by the rise in the contact angle. Moreover, there was an increase in the thickness (0.062 +/- 0.004-0.095 +/- 0.006 mm) and opacity (1.24 +/- 0.07-9.41 +/- 0.24) of the films with the addition of MOGR; however, tensile strength (7.30 +/- 0.50-4.92 +/- 0.34 MPa), elongation at break (32.41% +/- 1.0%-29.70% +/- 0.24%), and barrier properties decreased. Additionally, a rise in MOGR concentration corresponded to a rise in overall color difference Delta E (0.77 +/- 0.03-5.09 +/- 0.49) of the films. Notably, the incorporation of MOGR led to an increase in the antioxidant activity of the composite films, indicating potential applications in functional packaging materials.

    Pectin/sodium alginate films tailored with Acetyl-11-keto-beta-boswellic acid for active packaging
    (Elsevier, 2024) Bhatia, Saurabh; Shah, Yasir Abbas; Al-Harrasi, Ahmed; Jawad, Muhammad; Khan, Talha Shireen; Alam, Tanveer; Diblan, Sevgin
    The present study aimed to develop food packaging films by using a combination of pectin (PE) and sodium alginate (SA) enriched with Acetyl-11-keto-beta-boswellic acid (AKBA) as a functional or active ingredient. The fabricated films underwent comprehensive evaluation of their morphological, chemical, mechanical, barrier, optical, thermal, antioxidant, and antimicrobial properties. SEM and FTIR analysis showed that AKBA had good compatibility with film-forming components. The AKBA-loaded film samples exhibited a decrease in their barrier properties and tensile strength, but enhancements in both elongation at break and thickness values was observed. With the addition of AKBA, a significant increase (p < 0.05) in the ultraviolet barrier properties of the films and total colour variation (Delta E) was observed. TGA analysis of the films unveiled an improvement in thermal resistance with the incorporation of AKBA. Moreover, the films loaded with AKBA exhibited potent antioxidant activity in the ABTS and DPPH assay methods. Disk diffusion analysis showed the antimicrobial activity of AKBAloaded films against P. aeruginosa, highlighting the potential of AKBA as a natural antimicrobial agent for the safety of food products. The results demonstrate the practical application of PE and SA active films loaded with AKBA, particularly within the food packaging industry.
