The use of chitosan for the encapsulation of active components has gained interest in the last years due to its mucous adhesiveness, non-toxicity, biocompatibility and biodegradability. The benefits of encapsulating active agents in a polymer matrix include their protection from the surrounding medium or processing conditions and their controlled release.In this study chitosan nanoparticles were obtained for the encapsulation of phenolic compound. Chitosan anoparticles were prepared by ionic gelation of chitosan and sodium tripolyphosphate. X-ray diffraction, FTIR, and TEM were used to structurally characterize these chitosan nanoparticle products. The penolic compound were added to the sodium tripolyphosphate solution and this was added dropwise to the chitosan solution while stirring. The effect of the encapsulating systems on the phenolic compound stability and its release properties was analyzed.The products obtained allowed to control the release of phenolic compound and therefore these encapsulating methods are a promising technique for nutraceutical and cosmetic applications.
