    摘要:

    产地和季节是判断皱纹盘鲍品质的重要依据。采用电感耦合等离子体质谱(ICP-MS)法测定不同产地、不同季节皱纹盘鲍样本中16种无机元素的含量。建立皱纹盘鲍无机元素数据库,并结合聚类分析对18个皱纹盘鲍样品的产地进行区分,探讨无机元素溯源技术对皱纹盘鲍产地溯源的可行性。结果表明,皱纹盘鲍腹足中富含人体所需的微量元素,且无机元素含量和种类受季节及生长环境的影响,夏、秋两季元素含量普遍高于冬、春两季,秋季Fe元素含量十倍甚至百倍高于其它3季。聚类分析结果显示:分类与皱纹盘鲍样品的产地及海域分布显著相关,鉴别产地的效果与季节有关。

    Abstract:

    The origin and season are important basis for judging the quality of abalone. Inductively coupled plasma mass spectrometry(ICP-MS) was used to determine the content of 16 inorganic elements in the samples from different habitats and seasons. The inorganic element database of Haliotis discus hannai was established and combined with cluster analysis for 18 wrinkles. The abalone samples were divided into regions to explore the feasibility of traceability of inorganic elements to traceability of the origin of Haliotis discus hannai. The results showed that the abdomen of the Haliotis discus hannai disk was rich in trace elements required by the human body, and the content and type of inorganic elements were affected by the season and the growth environment. The content of elements in summer and autumn was generally higher than that in winter and spring, and the content of Fe in autumn was ten. Times or even a hundred times higher than the other three seasons. The results of cluster analysis showed that the classification was significantly correlated with the origin and sea area distribution of the Haliotis discus hannai samples, but the effect of identifying the origin was related to the season.
