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...

conclusions the current study results showed that silver nanoparticles produced by plantago ovata seed extract had an antibacterial effect on staphylococcus aureus which was resistant against cefixime, trimethoprim-sulfamethoxazole and penicillin. results the silver nanoparticles revealed gaussian distributions with the average diameter of 13 nm with some deviations, and results showed that the...

presently appearance of resistance to antifungal agents among aspergillus species is dramatically increasing. the objective of this study was to look at the in vitro activities of antifungal drugs against iranian clinical (from nail, bronchoalveolar lavage, paranasal sinus) isolated a. flavus strains. the susceptibility of 45 aflatoxigenic and non-aflatoxigenic aspergillus flavus strains were e...

aims: the synthetic colors are preferred by the food industry because of the variety of shades, intensity, uniformity, excellent solubility and stability. they are used in a variety of food products such as dairy products, beverages, baked products, confections and pet foods. food colors may have toxic effects on the human body. this study aimed to examine the amount of synthetic colors in some...
