Outline
To optimize the fresh-cut process of Dahuang (Rheum officinale Baill.) using analytic hierarchy process (AHP) -CRITIC method.
Taking the total amount of water soluble extract, total anthraquinone and free anthraquinone as the chemical composition quality control indicators, AHP-CRITIC analysis was used to comprehensively score and analyze Dahuang (Rheum officinale Baill.) decoction pieces, combined with process parameters such as trait scoring, drying time and energy consumption, prepared by different processes and screen for the best process conditions.
The appearance traits scoring results showed that the S1-S3 sample groups all had the best trait of X3-X6 decoction pieces. Different cutting techniques had a significant impact on the chemical composition of Dahuang (Rheum officinale Baill.) decoction pieces, with the most significant difference being the content of free anthraquinone. According to the comprehensive evaluation results, in the S1 sample group, X3-X7>C, and X3-X7 was a unique group, indicating that there were quality differences among different medicinal herb groups. In group S2, X4-X8>C, with X4-X6 clustered into one group. In group S3, X2-X7>C, with X4-X7 clustered into one group, indicating a quality difference within the group.
Dahuang (Rheum officinale Baill.) with a thickness of 3 cm, dried to a moisture content of 47%-59%, cut 5 mm thick slices, and dried at 60℃. Compared with traditional techniques, the fresh cutting process has the advantages of simple procedures, time-saving and energy-saving, and high content of effective ingredients. This method is the best way to cut while fresh and has feasibility in the production of Dahuang (Rheum officinale Baill.) decoction pieces
