Optimization of the remove process for ricinine from castor bean meal by water

The remove process for ricinine from castor bean meal was optimized by response surface methodology with removal rate of ricinine as investigate index.Based on the single-factor tests, the center combination experiment was established with three key factors of material liquid ratio, treatment temperature and treatment time.The remove process parameters of material liquid ratio, treatment temperature and treatment time was optimized through response surface analysis.The result showed that optimal remove process parameters were material liquid ratio of 1∶ 7, treatment temperature of 80℃ and treatment time of 6h.Under the optimal remove conditions, the removal rate of ricinine from castor bean meal was up to 84.12%.
