Abstract
The contents of inorganic elements such as Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, Li, K, Mg, Mn, Mo, Na, P, Pb, Zn, Se and Sr in egg of Poyang Lake anas platyrhynchos were determined by using inductively coupled plasma-atomic emission spectrometry (ICP-AES). The recoveries obtained by the standard addition method ranged between 84.4%-113.7%, and RSDs were lower than 8.02%. The measuring method provided better accuracy and precision. The determination results showed that the egg of Poyang lake anas platyrhynchos was rich in essential inorganic elements, and the contents of most of the inorganic elements in yolk were higher than protein. The contents of Cu, Fe, Mn and Zn in edible part of anas platyrhynchos egg were higher than Sheldrake, while the contents of Ca, P and Mg were less than Sheldrake. The contents of Ca, P, and Mg in anas platyrhynchos eggshell were less than Sheldrake
