| 摘 要： | 对丙酮酸乙酯进行微囊化研究,经过对比丙酮酸乙酯的包埋率确定最适的选材及条件,并对其各项性能指标进行测定。对制备的丙酮酸乙酯微囊进行喷雾干燥,得到丙酮酸乙酯微囊粉末。实验结果表明,最适壁材组合是阿拉伯胶与Hi-cap 100,壁材与水的最佳质量比例是1.5∶1,最佳喷雾干燥条件进风口温度为160℃,出风口温度为80℃。经过高效液相色谱检测丙酮酸乙酯微胶囊粉末包埋量29.4%,包埋率98%,微囊粉末表面光滑,无塌陷无裂缝,微囊符合要求。 |

| Abstract: | The optimum materials and conditions were studied for the microencapsulation of ethyl pyruvate by comparing the encapsulation rate of the microcapsules.The best results were obtained when gum arabic and Hi-cap 100 were used as shell materials,the ratio of shell materials and water was 1.5∶1,the best inlet air temperature was 160 ℃ and outlet air temperature was 80 ℃.Content determination of microencapsuled ethyl pyruvate powder by RP-HPLC.Content of microencapsuled ethyl pyruvate was 29.4% and encapsulation rate was 98%.Microencapsulated powder surface was smooth,no collapse,no cracks,micro-capsules to meet the requirements. |
| Keywords: | ethyl pyruvate microencapsulated spray drying |
