摘要:

利用响应面分析法对微胶囊补铁剂的影响因素,微胶囊的壁材质量与芯材体积之比、预冻时间和壁材质量浓度3 个因素进行优化。结果表明,壁材质量与芯材体积之比为19.5:1(g/mL)、壁材质量浓度为9.8g/100mL 和预冻时间13.0h,血红素微胶囊的包埋率为92.2%。

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
