Abstract:

Central composite design followed by multiple regression analysis and response surface analysis was employed to optimize hemoglobin microencapsulation. The results showed that the optimum conditions for hemoglobin microencapsulation were as follows: wall material-to-core material ratio 19.5:1 (g/mL), wall material concentration 9.8 g/100 mL and length of prefreezing time 13.0 h. Under such conditions, the embedding ratio of hemoglobin was 92.2%.

Key words: hemoglobin, microcapsule, optimization, response surface analysis
