[Aims] The intensively pungent odor of the capsaicin is not only uncomfortable for the operator in the applied process but also its efficiency decreases for its quick release properties in a given environment. The preparation and properties research on the microcapsules of PLA coated capsaicin was carried out. [Methods] The microcapsule of capsaicin was prepared with polylactic acid (PLA) wall and capsaicin core by the solvent evaporation process. [Results] FTIR analysis showed that the capsaicin was covered successfully with the PLA resin. SEM and laser particle size methods revealed that the particle size of the microcapsule was in the range of 3-5 um. Thermal analysis illustrated that the melting point and thermal stability of the microcapsules was improved within a certain range. [Conclusions] Thus, the application field of the microcapsulated capsaicin may be expanded.
