This work reviews the relevant information about the possibility of
producingmicroparticleswith chitosan, by a spray drying process,
for industrial applications. The applicability and the advantages of
chitosan and modified chitosan in the microencapsulation process
are discussed, with special emphasis on relevant operational
spray drying conditions, which affect the performance of the final
product, namely the efficiency and yield of the microencapsulation
process, the particle properties, like size, moisture and stability,
and the release time of active compounds.
The fundamental equations governing the controlled
release of active compounds and the application of controlled
release technology in food systems are presented.
