| Abstract:Antibacterial food packaging paper was coated with the composite coating including oregano essential oil-hydroxypropyl-β-cyclodextrin microcapsules that prepared via saturated aqueous solution method using hydroxypropyl-β-cyclodextrin as wall material and oregano essential oil as core material. The results showed that the inclusion rate of oregano essential oil was 83.69% with an excellent sustained release effect at the optimum preparation conditions of microcapsule with inclusion time of 3 h， inclusion temperature at 50 ℃ and the ratio of core material and wall material of 1∶8. In addition， both microcapsules and the prepared antibacterial food packaging paper had outstanding antibacterial properties against Staphylococcus aureus and Escherichia coli. |
