一种利用矿物元素含量鉴别山药产地的方法
摘要：
本发明公开了一种利用矿物元素含量鉴别山药产地的方法，包括以下步骤：(1)采集待检山药样品；(2)将所述山药样品去皮后打粉得到全粉样品进行消解；(3)检测所述消解后溶液中的Mg、Li、Cu、Rb、Sr和Ba的浓度，依次标记为XMg、XLi、XCu、XRb、XSr和XBa，单位为μg/g；按照判别模型(1)～(4)即可得到Y河北保定、Y山西运城、Y山东菏泽和Y河南焦作，则待检山药样品产地来源于Y河北保定、Y山西运城、Y山东菏泽和Y河南焦作中数值最大的区域。本发明使用不同的6种元素建立判别模型，具有测定元素种类少、检测成本低和判别正确率高的优点。
摘要（英）：

The invention discloses a method for identifying the production place of Chinese yam by means of the mineral element content. The method comprises the following steps of collecting a to-be-tested Chinese yam sample; 2, removing the skin of the Chinese yam sample to be powdered to obtain a whole-flour sample to be digested; 3, detecting the concentrations of Mg, Li, Cu, Rb, Sr and Ba in the digested solution to be marked as XMg, XLi, XCu, XRb, XSr and XBa in sequence, wherein the unit is microgram/gram. Y Hebei Baoding, Y Shanxi Yuncheng City, Y Shandong Heze and Y Henan Jiaozuo can be obtained according to discrimination models 1, 2, 3 and 4, and the to-be-tested Chinese yam sample is rooted in the region with the maximum numerical value from Y Hebei Baoding, Y Shanxi Yuncheng City, Y Shandong Heze and Y Henan Jiaozuo. Six different elements are adopted for building the discrimination models, and the method has the advantages of adopting few measuring element varieties, and being low in detection cost and high in discrimination accuracy.
