What is Spray Drying?

Spray drying is a method frequently used for microencapsulation in which an active ingredient is dissolved into a polymer solution, sprayed through a nozzle, and trapped in the resulting dried particles. Here is an introduction to the process and applications of spray drying: Spray drying is a method of producing a dry powder from a […]

Retained integrity of protein encapsulated in spray-dried chitosan microparticles

Abstract:┬áChitosan microparticles for delivery of proteins were prepared by spray-drying technique. The effects of formulation (molecular weight and concentration of chitosan) and process variables (inlet drying air temperature and spray rate) on size and morphology of microparticles were characterized. Size of microparticles was mainly controlled by formulation variables, while particle morphology was influenced by both […]
