Polyethylene and Polyamide Covers Containing Silver Nanoparticles in Reduction of the Mince Microbial Load
Objective(s): The use of new technologies, which can be realized as nanotechnology, is a novel approach in this sector. Covers made of silver nanoparticles effectively prevent and reduce invasion of microorganisms, compared with other conventional covers. This study was conducted to determine the effects of nanosilver covers in comparison with other conventional covers. <stron...
متن کاملMicrobial Production of Silver Nanoparticles
The biological process with the ability to study the shape of particles produced would therefore be a limelight of modern nanotechnology. The bacterial strain Escherichia coli, used for the biosynthesis of silver nanoparticles were investigated. These silver nanoparticles were characterized by means of UV–vis spectroscopy, particle size analyzer. The nanoparticles exhibited maximum absorbance a...
متن کاملComparative Study of Polyethylene and Polyamide Packaging Containing Silver Nanoparticles in Reduction of Meat Products (Mince Meat) Microbial Load
In order to measure the effect of antibacterial nano-covers, the direct contact of covers with meat products mixture was used as a control. Samples were contaminated with standard strains of gram-negative Escherichia coli and gram-positive bacteria Staphylococcus aureus. The samples were compared at specified times (0, 24, 48, and 72 hours). Despite the samples had large numbe...
