摘要

Fragrances are frequently added to a variety of products,including food,cosmetics and health products.However,the high volatility and instability of essence limit its application in some fields.In this study,mesoporous silica nanoparticles(MSNs)were prepared to encapsulate eugenol,which could reduce the volatilization of the fragrance molecules.A facile approach was presented to synthesize MSNs with three different pore diameters for encapsulating eugenol.In addition,the properties of MSNs including mean particle size,morphology,encapsulating efficiency and release tendency were characterized.Results showed that the larger the pore diameters of MSNs,the more aromatic molecules were adsorbed.Furthermore,the release mechanism was described as the smaller the pore diameters of MSNs,the slower the release of eugenol.
