“…In the case of DPPH assay, silver nanoparticles (AgNPs) are shown to be the highest DPPH scavenging activity at 100 μl (51.49 ± 3.33%) From both DPPH and FRAP assay, it has been concluded that CS film exhibited slightly less antioxidant activity due to the ability of chitosan to form stable macromolecule. After the incorporation of tea polyphenols leaves with AgNPs, antioxidant activity significantly increased as compared to the chitosan film (Zhang & Jiang, 2019). The green route has been adopted for the synthesis of silver nanoparticles by the research group of Subramanian for therapeutics potentials and clinical practices from the aqueous extract of Oldenlandiaum bellata.…”

Green chemistry is the significant field of research as it offers simple, cost-effective, easy, biocompatible and eco-friendly methods for the synthesis of nanomaterials. With the development of nanotechnology, the synthesis of silver nanoparticles (AgNPs) has become important areas of research due to their various applications in industrial, pharmacological and medicinal fields as they exhibited good antibacterial, antifungal, antioxidant, anti-inflammatory, antiviral, anticoagulant, thrombolytic, cytotoxic and photocatalytic properties due to their chemical stability and good biocompatibility.How to cite this article: Arif R, Uddin R.

Fish skin gelatin and chickpea protein isolated (G-CP) edible blend films incorporated with 0.25 and 0.5% copper sulfide nanoparticle (CuSNP) and Nigella sativa essential oil (MEO) (0.015 and 0.03%, w/w of protein) were prepared and optimized by the response surface methodology based on the central composite design (RSM-CCD). Antimicrobial activity, infrared spectroscopy (FTIR), X-ray diffraction (XRD), morphological characteristics and thermal attributes of composite films were examined. In general, the effect of CuSNPs and MEO on the properties of blended films, besides their inherent nature, is related to their interactions with the protein matrix and the synergistic effect on each other. As authenticated by the FTIR and XRD, the simultaneous use of CuSNPs and MEO because of the synergistic effect of CuSNPs on the antibacterial attributes of MEO and raising the content of antimicrobial components in the blend film expressed the highest antimicrobial functionality against E. coli. and S. aureus. Also, the results of microbiological and chemical tests of packaged minced meat revealed that the simultaneous use of MEO and CuSNP in the film has a positive synergistic effect in increasing the storage life of minced meat, as compared to the other samples.

“…Recent studies have shown that TP protect against oxidative stress-related diseases, including cancer, cardiovascular and degenerative diseases, as well as other biological activities (Higdon and Frei, 2003). In view of the advantages mentioned above as well as lowcost and safety of TP, the application of TP in the development of edible active packaging film has attracted the attention of many researchers in recent years, such as TP as carrier could improve the antioxidant and antibacterial properties of chitosan film (Zhang and Jiang, 2020). Another research reported that great antioxidant and antimicrobial activity as well as mechanical and water-barrier properties were exhibited in bioactive edible packaging films based on pomelo peel flours (Wu et al, 2019).…”

Usages of plastic casing have a number of drawbacks like generation of waste associated with the materials used to package foods and the source of natural casings is limited. So, the interest in the development of biodegradable collagen casing is increasing. For this reason, the present study aimed at developing a new type of collagen casing sprayed with Tea Polyphenols (TP), sodium alginate and sodium pyrophosphate. Box-Behnken Design (BBD) of Response Surface Methodology (RSM) was used to optimize concentrations of TP, sodium alginate and sodium pyrophosphate for the development of collagen casing. The optimization was done on the basis of responses viz. tensile force, tensile strength and elongation at break. The results showed that TP has a significant influence on tensile force and longitudinal tensile strength of collagen casing. Moreover, sodium alginate and sodium pyrophosphate had a significant effect on transverse elongation at break of collagen casing. The optimum level of different parameters resulting in collagen casing with maximum mechanical properties were obtained under conditions of 1.99% TP, 2.90% sodium alginate and 2.99% sodium pyrophosphate concentrations. Further verification test of the optimized conditions revealed a sufficient specific accuracy. The new type of collagen casing exhibited good mechanical properties, so these casings can be utilized for packaging in sausage industry.
