隆尧鸡腿葱矿物元素含量分析

为了研究隆尧鸡腿怱的矿物元素含量,以莱芜鸡腿葱作对比,采用火焰原子吸收光谱技术,对两种地理标志产品的鸡腿葱及其对应产地土壤中K、Ca、Na、Mg、Cu、Fe、Mn、Zn 8种元素进行了含量对比分析.结果显示,隆尧鸡腿葱中人体必需的矿物质元素含量(Ca、K、Mg等)明显高于莱芜鸡腿葱中的含量.8种矿物质元素的标准曲线均呈良好的线性相关性,相关系数R²>0.997 8,精密度为0.90%~3.61%,回收率为88.86%~105.56%,隆尧鸡腿葱中8种矿物质元素和对应土壤中的矿物质元素呈现显著相关性.隆尧鸡腿葱中Ca、Mg、Fe、Cu等元素含量与其土壤中对应元素含量呈极显著正相关.本研究结果将为隆尧鸡腿葱的种植提供科学根据.

Analysis of mineral elements in longyao jitui onions

Longyao jitui onion and Laiwu jitui onion are geographical indication products. In order to explore the mineral content in Longyao jitui onion. Analysis of mineral element content of Laiwu jitui onion as control and Longyao chicken leg onion. The content of K, Ca, Na, Mg, Cu, Fe, Mn, Zn in geographical indication products Longyao jitui onion, Laiwu jitui onion and their corresponding soil were analyzed by flame atomic absorption spectrometry. The results showed that the content of essential mineral elements(Ca, K, Mg, etc.)in Longyao jitui onion was significantly higher than that in Laiwu jitui onion. The standard curves of 8 kinds of mineral elements show good linear correlation, with correlation coefficient R² >0.997 8. The precision is 0.90%—3.61%, and the recovery is 88.86%—105.56%.There is a significant correlation between 8 mineral elements in Longyao jitui onion and the corresponding soil mineral elements. There is a significant positive correlation between the content of Ca, Mg, Fe, Cu and the corresponding elements in Longyao jitui onion. The results of this study will provide a scientific basis for the cultivation of Longyao jitui onion.
