Microencapsulação de corantes naturais em microesferas de quitosana preparadas pelo método de coacervação

Abstract

Chitosan is a natural amino polysaccharide, biodegradable, hydrophilic, biocompatible and low toxicity and can be found in the wall of microorganisms, especially in Mucor species, but especially in crustacean shells waste from the fishing industry. By owning several functional characteristics chitosan has emerged as an excellent encapsulating agent, either through the formation of microcapsules or microspheres. Several studies have been conducted to demonstrate the efficiency of chitosan microspheres in adsorption, protection and release of active compounds, thus benefiting, several segments, including pharmaceutical, food, agribusiness, chemical, biomedical and cosmetics.
