摘要:

由于蒸煮器具及分级差异等原因,传统黄精初加工效率不高,本研究采用滚筒烘房代替蒸煮工具进行杀青,在烘房内干燥,探究多花黄精机械化初加工工艺。多花黄精块茎按直径分为大、中、小。通过测定不同杀青和干燥时间下块茎的水分、灰分、多糖、浸出物含量,分析杀青时间和干燥时间对多花黄精品质的影响,优化多花黄精机械化初加工工艺。结果表明,在实际生产过程中,可按照大块茎确定杀青时间(杀青18.5 h),烘干时间按块茎大小分级进行,从而有效保证经初加工后多花黄精含水量、灰分及浸出物含量符合药典标准的同时,具有较高的多糖含量。

Abstract:

Traditional primary processing of Polygonatum cyrtonema Hua often suffers from low efficiency due to variations in steaming equipment and grading standards. In this study, a roller kiln was used to replace conventional steaming tools for fixation, followed by drying in the same kiln, to explore a mechanical primary processing method for Polygonatum cyrtonema Hua. Tubers were classified into large, medium, and small sizes based on diameter. By measuring the moisture, ash, polysaccharide, and extract contents under different fixation and drying durations, the effects of processing time on quality were analyzed to optimize the mechanical primary processing parameters. The results indicate that in practical production, the fixation time can be set according to large tubers, i.e., 18.5 hours, while drying time should be graded according to tuber size. This approach effectively ensures that the processed tubers meet the pharmacopoeial standards for moisture, ash, and extract content, while maintaining high polysaccharide levels.
