Effect of solvent on properties of pectin microspheres prepared by emulsion-dehydration technique

摘要

In the controlled release area,biodegradable microspheres are one of the most helpful devices to deliver materials in an effective,prolonged and safe manner[1].Biodegradable pectin microspheres could provide an approach for developing controlled release drug delivery systems.Pectin is a naturally occurring,non-toxic,water-soluble polysaccharide used in many food industries.Pectin has increasingly gained acceptance as a carrier polymer for site-specific delivery and controlled release dosage forms,such as beads,pellets,tablets,and films[1,2].
