摘要
目的:研究羟丙基淀粉空心胶囊的制备工艺。方法:以羟丙基淀粉为原料,通过溶胶、制坯、切割、套合等工序即制得羟丙基淀粉空心胶囊。结果:最佳工艺条件确定为:羟丙基淀粉和水的用量比为1∶2.5,溶胶温度和时间分别为60~80℃和1.5 h,胶槽温度和蘸胶速度分别为50~70℃和3~5次·min-1。结论:该工艺制得的胶囊质量可控,符合标准规定,适合工业化生产。
Objective: To study the preparation technique of vacant capsules of hydroxypropyl starch.Methods: Using hydroxypropyl starch as the raw material,the target product was prepared by sol preparing,sheet stamping,cutting,and superposition,sequentially. Results: The optimal preparation conditions were as follows: the reactant ratio of hydroxypropyl starch-water 1∶ 2. 5,sol dissolving temperature 50 ~ 70 ℃,sol dissolving time 1. 5 h,sheet stamping temperature 60 ~ 80 ℃,sheet stamping rate 3 ~ 5 cpm. Conclusion: The established preparation process for vacant capsules of hydroxypropyl starch is reliable in quality control,and the product meets the quality standards,so the new method is suitable for industrial production.
