Abstract

Today researchers pay more and more attention to the content of trace elements and heavy metals in food. Contents of trace elements and heavy metals in Chinese winter jujube fruit were analyzed by ICP-MS, the results showed that winter Chinese jujube contained plentiful trace elements, especially Ca (126.67 microg x g(-1) x FW), Mg (68.04 microg x g(-1) x FW), Sr (1691.39 ng x g(-1) x FW), Zn (787.26 ng x g(-1) x FW), Fe (512.84 ng x g(-1) x FW), Mn (495.42 ng x g(-1) x FW) and Mo (33.38 ng x g(-1) x FW), which is necessary for human health and can prolong the human life. But Chinese winter jujube contains little heavy metals and accords with relative national standard.

摘要

如今，研究人员越来越关注食品中微量元素和重金属的含量。采用电感耦合等离子体质谱法（ICP-MS）分析了冬枣果实中微量元素和重金属的含量，结果表明，冬枣含有丰富的微量元素，尤其是钙（126.67微克×克⁻¹×鲜重）、镁（68.04微克×克⁻¹×鲜重）、锶（1691.39纳克×克⁻¹×鲜重）、锌（787.26纳克×克⁻¹×鲜重）、铁（512.84纳克×克⁻¹×鲜重）、锰（495.42纳克×克⁻¹×鲜重）和钼（33.38纳克×克⁻¹×鲜重），这些对人体健康是必需的，并且可以延长人类寿命。但冬枣中重金属含量很少，符合国家相关标准。
