results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

biodegradable polysacharyd-based film was developed by incorporating pimpinella affinis essential oil (pao) into methyle cellulose (mc) at level of 0.5%, 1% and 1.5% v/v. then, its antimicrobial activity tested against 7 bacteria include staphylococcus aureus (ptcc 1431), pseudomonas aeruginosa (ptcc 1151), pseudomonas putida(ptcc 1691),esherichia coli (ptcc 3315), listeria monocytogenes (ptcc ...

ABSTRACT: The use of new compounds to increase the shelf life of more perishable foods based on nanoparticles and biodegradable polymers have been developed in packaging. Chitosan (Cts) is a natural biopolymer with excellent biodegradability and nontoxicity and antibacterial effect. In this research antibacterial copper nanoparticles (CuNPs) were incorporated in the biodegradable chitosan matri...

Cefadroxil drug loaded biopolymeric films of chitosan-furfural schiff base were prepared by reacting chitosan with furfural in presence of acetic acid and perchloric acid respectively for the external use. Prepared films were evaluated for their strength, swelling index, thickness, drug content, uniformity, tensile strength, percent elongation, FTIR spectral analysis and SEM. The results of in ...
