The contents of four essential elements, Mn, Fe, Cu, Zn, were determined in 152 samples of pork and duck liver paste produced in Spain. The average concentration levels that were measured are 1.2 micrograms/g for Mn, 51.6 micrograms/g for Fe, 6.1 micrograms/g for Cu and 22.2 micrograms/g for Zn in pork liver pastes and 0.8 micrograms/g for Mn, 32.3 micrograms/g for Fe, 2.7 micrograms/g for Cu and 12.9 micrograms/g for Zn in duck liver pastes. The possible sources of these trace elements were investigated: product formulation, technological processing and packaging. Liver, the basic raw material, is the main source of trace elements in the final product; significantly high concentrations have been observed for all of the elements that were analysed in the pork liver pastes compared with the duck liver pastes.
对西班牙生产的152份猪肝酱和鸭肝酱样本中的四种必需元素锰、铁、铜、锌的含量进行了测定。测得的猪肝酱中锰的平均浓度水平为1.2微克/克，铁为51.6微克/克，铜为6.1微克/克，锌为22.2微克/克；鸭肝酱中锰为0.8微克/克，铁为32.3微克/克，铜为2.7微克/克，锌为12.9微克/克。对这些微量元素的可能来源进行了调查：产品配方、工艺加工和包装。肝脏作为基本原料，是最终产品中微量元素的主要来源；与鸭肝酱相比，猪肝酱中所有分析元素的浓度均显著较高。
