Uniform design method is preferred for sesame oil extraction (2)
1.1 Microwave assisted extraction
The sesame sample was weighed to 40 g, placed in a flask, and the organic solvent selected in a certain ratio was added. After being placed in a microwave oven for 40 s, it was taken out and cooled to room temperature, and the solution was carefully poured out. Add the selected organic solvent and re-inject it into the microwave for 40 s. Repeat the above steps until the radiation time accumulates to the specified time. Finally, the residue of the flask was washed with the selected organic solvent, and the resulting solution was filtered into a flask, and distilled under reduced pressure to obtain sesame oil, which was dried over anhydrous Na 2 SO 4 for 24 h and weighed.
experimental design
The four factors of extraction radiation time, solvent, microwave power and mass ratio of material to solvent were used as variables. A four-factor, three-level orthogonal test was performed. After the experimental data were processed to obtain the optimum process conditions, the sesame oil microwave extraction experiment was carried out under this condition, and the extraction rate under the optimal conditions was obtained to verify the data processing results.
