The chitosan/SiOx fresh-keeping film was prepared by combining chitosan with nano-SiOx,pre-modified with anion surfactant (SDS). Microstructure was characterized by IR spectroscopy and TEM. The results show that strong hydrogen bonds are formed between nano-SiOx and chitosan.Additionally, many properties of the composite film were investigated and it was found that the properties of the composite film, such as water vapor transmission rate (WVTR), optical transparency(T%), Mechanical, crack and gas transmission, were increased and improved obviously. Besides, the composite film had superior antibacterial activity both for gram-positive and gram-negative bacteria.The data reveals that applying of the composite films coating effectively maintains the quality attributes of fruit and vegetables.
