Objective: To prepare binary complexes of rutin and bismuth microcapsules
and evaluate its quality. Method: With homemade binary complexes of rutin and bismuth as raw material
binary complexes of rutin and bismuth microcapsules was prepared by complex coacervation method
preparation technology was optimized by orthogonal test;Quality evaluation was finished by detecting encapsulation efficiency
verification test and particle size. Result: Optimum preparation condition of binary complexes of rutin and bismuth microcapsules was:capsule material-capsule core 6:1
encysted pH 3.5
capsule temperature 60℃
curing time 1.5 h. Conclusion: Applying optimized technology to prepare microcapsules
encapsulation efficiency was more than 40% with good reproducibility
and particle size of 90% microcapsules was 15-85 μm.
