采用火焰原子吸收法对美人酥、红酥脆和满天红3个不同品种的红梨果实中K、Fe、Zn、Ca、Cu、Mg、Mn等营养元素的含量进行了研究。结果表明，各元素在工作曲线范围内线性关系良好，回收率为98%~ 104%，结果令人满意。三个不同品种的红梨果实中含有丰富的营养元素，具有较高的营养价值。3个红梨品种果实中不同营养元素的含量顺序为K>Fe>Zn>Ca>Cu>Mg>Mn。3个红梨品种果实中K、Zn、Mg、Mn含量顺序为美人酥>红酥脆>满天红; Fe、Cu含量顺序为红酥脆>满天红>美人酥; Ca含量顺序为满天红>红酥脆>美人酥; 7种营养元素总含量顺序为红酥脆>美人酥>满天红。
A study was carried out on the contents of nutritional elements such as K, Fe, Zn, Ca, Cu, Mg and Mn in three different red pear varieties, namely Meirensu, Hongsucui and Mantianhongs, by flame atomic absorption. The results indicated that the linear relationships for different elements within the limits of working curves are good, and the range of recovery is 98%-104%, hence showing that the results asre satisfactory. There are abundant nutritional elements in fruits of the three different red pear varieties, meaning that they all have a relatively high nutritive value. In fruits of the three red pear varieties, the content sequence of different nutritional elements was found to be K>Fe>Zn>Ca>Cu>Mg>Mn. In fruits of the three different red pear varieties, the content sequence of K, Zn, Mg and Mn was Meirensu> Hongsucui>Mantianhong; the content sequence of Fe and Cu was Hongsucui>Mantianhong>Meirensu; and the content sequence of Ca was Mantianhong>Hongsucui> Meirensu; and the total content sequence of seven nutritional elements was Hongsucui>Meirensu>Mantianhong.
