“…Antimicrobial agents such as organic acids, bacteriocins and spice extracts have been tested for their ability to control meat spoilage [7]. Nano titanium dioxide (nano-TiO 2 ) material is a kind of important inorganic materials.Due to its small particle size,chemical stability,high catalytic activity,high oxidative ability,nontoxicity,harmlessness,low price,no secondary pollution,etc.It has abroad applied in various fields such as energy,information,materials,enviromental protection, antibacterial and so on [8].Nano-TiO 2 is an inert metal oxide,which is widely used in food color additive [9].…”
