犍为干姜适宜加工方法的讨论【摘要】 目的筛选犍为县干姜 GAP 基地干姜最适宜的加工方法。方法采纳 HPLC法和挥发油测定法,以干姜辛辣成分 6-姜酚、挥发油含量、药材性状为指标对犍为县不同加工方法的干姜进行质量对比讨论。结果不同加工方法对干姜质量有显着影响。结论犍为县产干姜最适宜的加工方法为:用不去皮完整块姜在 55℃低温烘干。【关键词】 干姜 加工方法 6-姜酚 挥发油 高效液相色谱法 Effects of Different Processing Methods on Quality of Dried Ginger from Qianwei Abstract:ObjectiveTo provide a guideline on processing methods of dried Ginger from samples were dried in different processing methods and at 4 temperatures. The contents of 6-gingerol and volatile oil of each sample were measured by HPLC and the method described in CP respectively. The pharmacognostical identifications of processed samples were also compared. ResultsProcessing methods and drying temperature significantly affected the quality of dry best processing method for fresh ginger from Qianwei should be that to dry fresh one at 55℃ unpeeled.
