Comparison of Earthworm Smash-dissolution Dynamics Using Conventional Homogenized and Wet Ultrafine Grinding Process
地龙湿法超微粉碎与常规匀浆的“粉碎- 溶出”动力学比较研究

This study was aimed to make a preliminary comparison of earthworm extraction efficiency using conventional homogenized and wet ultrafine grinding process, respectively. The curve of "time-particle size distribution" and "time -protein accumulation dissolution rate" was established through particle size analysis, scanning electron-microscopy and protein determination with Bradford method to make a comparison of earthworm smashdissolution dynamics. And a comparison of extract composition with HPLC fingerprint was made. The results shows that the peak shapes of extracts from both processes were basically the same. While the composition peak area extracted with wet ultrafine grinding process were significantly higher than conventional homogenized process. It indicates that earthworm extracted efficiency using wet ultrafine grinding process were obviously higher than conventional homogenized process. Wet ultrafine grinding can be used to extract earthworm compositions. The whole process is quick, simple and suitable for large-scale promotion.
