| Abstract: | Objective] To establish a method for determination of residual solvents in soybean meal.Method] The effects of several methods of new and old national standard and AOCS on the determination of residual solvent-extracted oil No.6 in soybean meal were discussed.The mechanism of solvent extraction was analyzed and the suitable extraction solvent was found.Result] DMF can be used as solvent to extract solvent-extracted oil No.6 in soybean meal.The extraction efficiency is more than 90％,and the gas liquid equilibrium constant K3 is also larger.The method has high sensitivity and good reproducibility.Conclusion] Satisfactory results were obtained in the method of quality control,which could provide reference for the determination of residual solvents in soybean meal. |
