摘　　要：As a nutritious cold chain food,cheese is susceptible to Listeria monocytogenes contamination.In order to prevent and control Listeria monocytogenes in cheese safely and efficiently,maintain the sensory quality during sale,this paper developed a novel nanofiber membrane with good mechanical strength,hydrophobicity,thermal stability,release performance and bacteriostatic performance as food active packaging.In this study,zein was introduced and electrospun to form a reliable carrier to embed and deliver citral in the cavity of HP-β-CD(Hydroxypropyl-β-cyclodextrin).We found that the zein-based nanofiber membranes showed preferable tensile properties and hydrophobicity with 4%(w:v)addition of citral/HP-β-CD inclusion complex.Meanwhile,the thermal stability and release property of citral were significantly improved by embedding in HP-β-CD and loading into zein-base nanofiber membranes.Moreover,after packaged by Zein nanofiber membrane encapsulated with citral/HP-β-CD inclusion complex under the storage conditions of 4℃ and 12℃,the growth of Listeria monocytogenes in four kinds of cheeses was inhibited to a certain degree.The texture and sensory quality of the four cheeses at the two temperatures and the color quality under the low temperature condition of 4℃ did not change significantly.In summary,Zein nanofiber membranes encapsulated with citral/HP-β-CD inclusion complex has potential application prospects in the field of food active packaging.
