Abstract: In order to get the cell wall disruption superfine powder of Momordica charantia L., release fully the active ingredients stored in cell and provide raw materials for tea bag and tablet processing, in the process of Momordica charantia L., a variable parameter ball mill was used for the superfine grinding of Momordica charantia L.. An orthogonal experimental design with four factors at two levels was adopted. A mathematical model describing effects of selected parameters on experiment criterion of the cell wall disruption efficiency was developed. By optimal calculation a set of optimum parameters for the best superfine grinding of Momordica charantia L. was achieved with grinding drum rotation speed 423-436 r/min, grinding time1.9-2.1 h, ratio of ball to Momordica charantia L. 6.7-7.2, and moisture content of Momordica charantia L. 5.6%-6.7% . The optimized superfine grinding gave cell wall disruption efficiency as high as 95% . Result showed that the cell wall disruption superfine grinding could greatly improve the dissolution rate and quantity of the total saponins in Momordica charantia L.. This research result laid a basic foundation for the efficient utilization of Momordica charantia L. in food and cosmetic industries.
