摘要
为研究干燥方法对砂仁药材品质的影响.本研究在采收期采收不同种植地块的鲜砂仁样品,通过自然晾晒、50 ℃烘烤15h+堆捂10h+40 ℃烘烤、40 ℃烘烤、50 ℃烘烤、冷冻干燥等5种不同干燥方法对鲜砂仁进行干燥,观察干燥后砂仁样品的外观性状,测定挥发油和乙酸龙脑酯成分的含量.结果表明,冷冻干燥的砂仁果皮颜色为浅褐色,质地较软,其余加工干燥的砂仁果皮颜色为深褐色,质地相对较硬;果皮与种子团紧贴程度以50 ℃烘烤15h+堆捂10h+40℃烘烤和冷冻干燥的较好,其余均有一定的空隙;种子团内颗粒紧实度最差的为冷冻干燥,较松散易分开,其余干燥的样品均较紧实不易分开;冷冻干燥的种子团颜色为浅褐色,其余干燥的为深褐色;挥发油和乙酸龙脑酯含量最低的为冷冻干燥,其余干燥所得的均较高,但组间无明显差异.砂仁最佳干燥方法为50 ℃烘烤15 h后趁热堆捂10 h,再继续用40 ℃烘烤至干燥,该方法加工的砂仁品质最佳,外观品质好、挥发油及乙酸龙脑酯含量高.
Abstract
To study the effect of different drying methods on the quality of Amomum fructus.Harvest of fresh litter samples from different planting plots during the harvest period,dring the fresh sand by 5 different drysing methods including natural drying,50 ℃ baking 15 h+heap cover 10 h+40 ℃ baking,40 ℃ baking,50 ℃ baking and freeze-drying,to observe the appearance properties of dried amomum sam-ples,determined the content of volatile oil and bornyl acetate.Frozen-dried amomum fructus peel is pale brown in color with a soft texture,the rest of the processed dried amomum fructus peel is dark brown in color and relatively hard in texture;fruit peel and seed group close to the degree of 50 ℃ baking 15 h+heap cover 10 h+40 ℃ baking and freeze-drying is better,the rest all have certain interval;the worst particle compaction in the seed mass was the freeze-dried one,loose and easy to separate,the remaining dry samples are relatively compact and not easy to separate;frozen-dried seed mass color is light brown,the rest of the dry one is dark brown;the lowest content of the volatile oil and bornyl acetate were freeze-dried,the rest of the drying income is higher,there were no significant differences between the groups.The best drying method is 50 ℃ baking 15 h+heap cover 10 h+40 ℃ baking,it is good appearance quality,high content in volatile oil and bornyl acetate.
