目的 探讨不同产地初加工方法对黔产灰毡毛忍冬外观性状、品质成分和加工效率多方面的影响,为灰毡毛忍冬产地加工方法的优选提供依据。方法 采用传统加工方法组(晒干、蒸后晒干、阴干、蒸后阴干)、恒温烘干组(50、60、70、80℃)、变温烘干组(50→60℃、50→70℃、50→80℃)共11种方法加工灰毡毛忍冬,对加工品从颜色和香气等外观指标,水分、总灰分、酸不溶性灰分、绿原酸、总皂苷等成分指标,加工时间和折干率等效率指标分别进行测定。结果 综合外观性状、品质成分和加工效率多方面的因素,11种加工方法中,50℃恒温和变温方法的综合关联度值在0.94~0.96,远高于其他方法,其中50→60℃方法的综合关联度值最高,达到了0.959 8。结论 综合来看,变温干燥是灰毡毛忍冬较好的产地初加工方法,该方法可作为基地规模化加工灰毡毛忍冬的重要技术手段。

Objective To investigate the effects of different processing methods on the appearance, quality components and processing efficiency of Lonicera macranthoides that produced in Guizhou Province, in order to provide basis for the optimization of processing methods. Methods Eleven processing methods were used such as the traditional method group (sun drying, sun drying after steaming, drying in shade, and drying in shade after steaming), constant temperature drying group (50, 60, 70, and 80℃) and variable temperature drying group (50→60℃, 50→70℃, 50→80℃). Then the indicators such as color, aroma, moisture, total ash, acid insoluble ash, chlorogenic acid, total saponins, processing time, and drying rate were measured. Results According to all the indicators, the comprehensive correlation degree of the 50℃ and the variable temperature drying method was between 0.94 and 0.96, which was much higher than other methods, and the comprehensive correlation degree of 50→60℃ degrees was the highest, reaching 0.959 8. Conclusion In conclusion variable temperature drying method is a better processing method for L. macranthoides. This method can be used as an important technical means for large-scale processing.
