云南石屏那刀辣与小米辣矿质元素含量分析
|
摘要
[目的]为云南石屏县那刀辣与小米辣的开发利用提供科学依据。[方法]以石屏县那刀辣与小米辣为材料,采用原子吸收光谱法测定其中的矿质元素含量。[结果]小米辣Ca、Fe含量分别比那刀辣高235.0、4.1 mg/kg,那刀辣Mg、Zn、Cu、Co、Ni含量分别比小米辣高71.20、0.84、0.02、0.125、1.05 mg/kg;2种辣椒Mg含量最高,分别为1 948.3和1 877.1 mg/kg,Ca含量次之,分别为347.5、582.5 mg/kg,Co含量最低,分别为0.650 0、0.525 0 mg/kg;2种辣椒所分析7种矿质元素的含量依次为:Mg>Ca>Fe>Zn>Cu>Ni>Co,矿质元素的加标回收率为97.18%~107.77%,测定结果的相对标准偏差为0.43%~1.86%。[结论]那刀辣与小米辣中矿质元素含量存在一定差异。
[Objective] The aim was to provide the scientific basis for the development and utilization of Nadao capsicum and Xiaomi capsicum from Shiping of Yunnan Province.[Method] With Nadao capsicum and Xiaomi capsicum from Shiping Country as the materials,their mineral element contents was determined by atomic absorption spectrometry.[Result] The contents of Ca and Fe in Xiaomi capsicum were higher 235.0 and 4.1 mg/kg than those in Nadao capsicum resp.,while the contents of Mg,Zn,Cu,Co and Ni in Nadao capsicum were higher 71.20,0.84,0.02,0.125 and 1.05 mg/kg than those in Xiaomi capsicum.Mg content in 2 kinds of capsicum was the highest,being 1 948.3 and 1 877.1 mg/kg resp.,and the following was that of Ca,being 347.5 and 582.5 mg/kg resp.,Co content in 2 kinds of capsicum was the lowest,being 0.650 0 and 0.525 0mg/kg resp.The contents of 7 kinds of analyzed mineral element in 2 kinds of capsicum in order was: Mg>Ca>Fe>Zn>Cu> Ni>Co,and the recovery of standard addition of the mineral elements was 97.18%-107.77% with relative standard deviation of 0.43%-1.86%.[Conclusion] The mineral element contents in Nadao capsicum and Xiaomi capsicum had some differences.
