| Abstract: |
| In this study， the co-coagulation method was employed to prepare SEO@CS/CNF microcapsules using sandalwood essential oil （SEO） as the core material， chitosan （CS） and cellulose nanofibril （CNF） as the composite shell materials， Tween-80 as the emulsifier， and sodium tripolyphosphate （TPP） as the cross-linking agent， with the aim of achieving effectively protecting SEO and controlled-release. Using the average particle size of the microcapsules and the SEO encapsulation efficiency as key evaluation indicators， the optimum process conditions for microcapsule preparation were determined to be a mass ratio CS to CNF of 8∶1， a mass ratio of the core material to the wall material of 4∶1， and a system pH value of 4.5. Under the optimum conditions， the SEO@CS/CNF microcapsules exhibited an SEO encapsulation efficiency of 94%， a zeta potential of 7.0 mV， and an average particle size of 4.4 µm. They also demonstrated excellent thermal stability and slow-release performance. After 14 days of storage in an aqueous environment， the cumulative release rate of SEO from SEO@CS/CNF microcapsules was only 55.3%. The results of the slow-release kinetics fitting indicated that the sustained-release process of SEO from SEO@CS/CNF microcapsules followed a first-order kinetic model， and the release mechanism was primarily non-conventional transport. |
