Microencapsulated jasmine perfume was prepared by double-layered capsulation method to improve its thermal stability and sustained-release, in which melamine-formaldehyde and acrylic ester were chose as wall materials. The obtained microcapsules were characterized in terms of morphology and chemical structure by scanning electron microscopy ( SEM), Fourier infrared spectrometer ( FT-IR) and scanning electron microscopy ( SEM), and results showed that the oil-soluble fragrance had been encapsulated completely. Furthermore, weight loss rate of capsulated jasmine perfume was also measured by thermo-gravimetry analysis. It was found that in case of single-layered microcapsule, the weight loss was kept in constant before 200 ℃ , and then accelerated rapidly from 200 ℃ to 250 ℃ . The weight loss rates of double-layered microcapsules, on the other hand, were much lower than those of single-layered ones. Thermostat thermal weight loss in 50 ℃ showed that the perfume release rate of double-layered microcapsule was significantly lower than that of single-layered one, and the weight loss rate was less than 10. 1% after 27 days.
