| 摘 要： | 采用乳化-凝聚法,在油包水(W/O)体系中制备壳聚糖/明胶(Cs/Gel)复合微球,研究乳化剂用量、搅拌速率和水油比等因素对微球粒径以及脱水过程中的丙酮浓度对Cs/Gel复合微球形貌的影响.研究结果表明:乳化剂浓度较低时,微球的粒径随乳化剂浓度的增加呈降低趋势,当乳化剂浓度高于0.012 g·mL-1时微球粒径不再发生...

| Abstract: | Chitosan/gelatin(Cs/Gel) composite microspheres were prepared through emulsion-coagulation method.The influences of preparation parameters,including emulsifier concentration,stirring speed and water/oil ratio,on microsphere's particle size and the concentration of acetone solution in the course of dehydration on the surface morphology were investigated.The research results indicate that the particle size of the microsphere decreases with increasing the concentration of the emulsifier;the particle size of th... |
