[Abstract] Objective: To explore the optimum technological conditions for the drying and sterilization of Angelica sinensis. Methods: The factors were screened by single factor test and L9 ( 34 ) orthogonal test. The total number of colonies of Angelica sinensis, ferulic acid content and final water content were comprehensively evaluated. Results: The optimal microwave drying and sterilization process parameters of Angelica sinensis was 15% water content of Angelica, microwave power 12 kw, microwave rotation speed 1030 r·s - 1 and sample loading 10 kg·m - 2 .
Conclusion: By optimizing the process of Angelica microwave drying equipment, the loss of ferulic acid, the active ingredient of Angelica sinensis, can be reduced, and the purpose of effective sterilization can also be achieved. The use of improving and improving the quality of products can provide scientific research for the processing and production of Gansu and the national Angelica. in accordance with.
