AgNPs-fortified gelatin film, fish skin, bioactive packaging


Biodegradable films were prepared using fish skins treated with silver nanoparticles and gelatin as biodegradable polymers. Different volume of silver nanoparticle solution (15, 10, and 5 ml) were used in producing the edible films. the films were evaluated for their inhibitory effectiveness against some types of bacteria that cause food spoilage. The results showed that the gelatin films containing 10 ml of silver nanoparticle solution gave effective activity against Bacteria for all strains tested. The results also showed an improvement in the mechanical properties of the coating supported with silver nanoparticles, as the thickness increased to 0.9 mm compared to the regular control gelatin film of 0.5 mm. Therefore, the tensile strength and elongation rate of the nano-silver treated films increased compared to the control regular coatings. The results also showed that the solubility of the regular gelatin film was 45.2% which significantly diffed from the solubility of the Nano-silver gelatin treated film, which recorded approximately half the solubility (23.3%).
