主　　题：Active packaging Basil essential oil Silica nanoparticles Antimicrobial activity Chitosan Biofilm 

摘      要：Active packaging based on biomaterials and essential oils is an alternate for plastic ***,essential oils are chemically and physiologically labile,and they have strong scents,limiting their use as antimicrobial additives in ***,in this investigation,basil oil was encapsulated in silica nanoparticles(basil oil@SiNPs)and combined with chitosan films(basil oil@SiNPs@chitosan).Scanning electron microscopy(SEM),Transmission electron microscopy(TEM),X-ray diffraction(XRD),surface area and Brunauer-Emmett-Teller(BET)analysis,encapsulation and loading%were used to evaluate basil oil@*** surface area of SiNPs decreased from 59.006 to 43.86 cm^(2)/g due to basil oil *** encapsulation and loading%were 81.96,65.87,48.48 and 43.13,37.64,33.44%for 2,1.5,and 1 mL of basil oil,***-transform infrared(FT-IR),XRD,thermogravimetric analysis(TG),mechanical,wettability,water vapor permeability(WVP),oxygen permeability(OP)features;water vapor sorption isotherms and antimicrobial inhibition tests were used to describe the produced basil oil@SiNPs@chitosan *** contact angles and activation energy increased from 89.0◦to 110.9◦and-11.97 to-20.40 kJ/mol,respectively after addition of basil oil@***,WVP decreased from 5.9580×10^(-1)±0.33 to 4.2413×10^(-1)±0.55 ***.m^(-2).h^(-1).kPa^(-1)and OP increased from 4.094×10^(-4)±0.52 to 6.715×10^(-5)±0.32(g.m^(-2).day^(-1).atm^(-1)).The four models Guggenheim-Anderson-de Boer(GAB),Smith,Henderson and SIPSI were suitable for describing the moisture sorption of basil oil@SiNPs@chitosan *** oil@SiNPs has antimicrobial inhibition against Gram positive and negative bacteria,pathogenic yeast.
