Abstract: A nanocomposite film and a method of producing nanocomposite films. The method includes the steps of preparing an aqueous Crocus sativus extract; dropwise adding silver nitrate solution to a dispersion of titanium dioxide nanoparticles to obtain a mixture; and dropwise adding the aqueous Crocus sativus extract to the mixture with continuous stirring to obtain nanocomposite powder.

Abstract: A nanoemulsion composition for use in food packaging to enhance antimicrobial properties, barrier properties, and stability thereof, the nanoemulsion composition includes lavender essential oil as an oil phase and Viper's-buglosses aqueous extract as an aqueous phase. The composition is prepared using a suitable concentration of emulsifying agent with homogenization and sonification techniques.

Abstract: The present invention is directed to a method to produce silver nanoparticles. The method includes the steps of dropwise addition of silver nitrate solution to a carboxymethyl cellulose solution (1%) while stirring. The solution is subjected to ultrasonic irradiation for 30 minutes. The first indication of silver nanoparticles being synthesized can be change in the color of the solution to yellowish-brown after Ultrasonication. The solution can thereafter be subjected to microwave irradiations. After the predetermined duration, the produced silver nanoparticles can be separated from the solution. The nanoparticles can be washed and freeze dried.

Abstract: The present invention relates to a method for producing antimicrobial nanofilms packaging cover based on Titanium nano-dioxide through extrusion for extension of food shelf-life. The method comprises the steps of providing nano-silver and nano-clay particles which are antimicrobial agents to enhance mechanical properties of packaging in food industry; and evaluating effects of nano clay and nano silver packaging on the growth of these bacteria within 6 days of shelf life keeping at 4° C. The silver and clay nanoparticles are analyzed using AFM, SEM, FESEM, EDX, FTIR and TEM, wherein the size of clay and silver nanoparticles are measured 15 nm and 35 nm, respectively.
