冬枣果实中微量元素和重金属含量研究
Content of Trace Elements and Heavy Metals in Chinese Winter Jujube Fruit
【摘要】 食品中微量元素和重金属含量已经成为食品研究中的两个热点。文章选用鲜冬枣果实作为材料,通过ICP-MS研究了冬枣中微量元素和重金属的含量。结果显示,冬枣中含有丰富的微量元素,尤其是钙(126.67μg·g-1·FW)、镁(68.04μg·g-1·FW)、锶(1691.39ng·g-1·FW)、锌(787.26ng·g-1·FW)、铁(512.84ng·g-1·FW)、锰(495.42ng·g-1·FW)和钼(33.38ng·g-1·FW)等,这些元素对于维护人体健康和长寿具有积极作用。重金属含量普遍较低,符合国家相关行业标准。所以冬枣果实如果在无污染的地区种植,是一种营养丰富和安全的鲜食食品。
【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 μg·g-1·FW),Mg(68.04 μg·g-1·FW),Sr(1 691.39 ng·g-1·FW),Zn(787.26 ng·g-1·FW),Fe(512.84 ng·g-1·FW),Mn(495.42 ng·g-1·FW) and Mo(33.38 ng·g-1·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.
