Abstract :
The research aim was to investigate preparation and characterisation of ovalbumin-loaded alginate microspheres produced by aerosolisation and study its in vitro release. Calcium chloride was use as crosslinking agent with crosslinking time of 30 and 120 minutes. Aerosolization technique offers a simple, fast, produce homogenous microspheres and a safe technique with no organic solvent involved. Ovalbuin-loaded-alginate microspheres were evaluated in terms of size, morphology, encapsulation efficiency, loadings of protein and yield of microspheres. In vitro release study was conducetd in simulated gastric fluid (HCl pH 1.2) and simulated intestinal fluid (PBS pH 7.4). Results showed that smaller particle size (12-23 µm) and higher encapsulation efficiency, loading and yield was produced by inceasing alginate and crosslinker concentration as well as increasing crosslinking time from 30 minutes to 120 minutes. Furthermore, by increasing alginate concentration and crosslinking time, release of ovalbumin from alginate microspheres decreased and slower in pH 1,2 during 2 hours incubationfollowed by 6 hours incubation in PBS pH 7,4. These findings indicated its potential for oral protein delivery system.
