Title: Study on Extracting Coixendide and Microencapsulation
Abstract: Microencapsulation of coixendide extracted by acetone from coix was studied. The results showed that under the roomtemperature adding 3 5 times of acetone into the dry coix powder for 3 times and extraction for 8h each time were optimal. Most coixendide can be extracted. Sodium alginate whose solution concentration was 10g/L was selected as the wallmaterial of coixendide microencap sulation. The ratio of coixendide to sodium alginate was 0 6∶1. The concentration of emulsifier MG and SE was 1g/L and 0 5g/L respectively. The emulsification temperature was 50~60℃and the concentration of CaCl2 solution was 10g/L. After the capsules were dried under 45℃,the moisture content and the retention ratio of coixendide were 13 5%and 81 8%.
