Encapsulation of Phenolic Compound from Star Fruit with Chitosan Nanoparticle

Abstract

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.
