摘　　要：本试验旨在研究不同蛋白原料中常量元素、微量元素、重金属元素等26种元素的含量及分布规律,分析其含量差异可能成因,为不同蛋白原料科学利用提供数据依据。本实验利用电感耦合等离子体质谱(ICP-MS)技术,系统分析了鸡肉粉、鱼粉、花生浓缩蛋白、大豆浓缩蛋白、棉籽蛋白、菌体蛋白、藻粉和昆虫粉等8种15批次的蛋白原料中元素组成及分布规律。结果表明,所有蛋白原料均含有供试矿物质元素,不同种类的蛋白原料矿物质元素含量差异较大(P<0.05);某些元素在同种不同来源的原料中含量水平差异显著(P<0.05);存在蛋白原料中单一元素含量明显高于其他原料的现象(P<0.05)。通过对数据结果的分析有利于推广应用新型蛋白质饲料原料,促进我国养殖业的可持续发展。The aim of this experiment was to study the content and distribution of 26 elements such as macroelement,microelement and heavy metal element in different protein raw materials,and analyze the possible causes of their content differences,so as to provide data basis for scientific utilization of different protein raw materials.The composition and distribution of 15 batches of 8 protein raw materials,including chicken meal,fish meal,peanut protein concentrate,soybean protein concentrate,cottonseed protein,bacterial protein,algae meal and insect meal,were systematically analyzed by inductively coupled plasma mass spectrometry(ICP-MS).The experimental data showed that all the protein raw materials contained the tested mineral elements,and the mineral elements contents of different kinds of protein raw materials were significantly different(P<0.05).The content levels of some elements in the same raw materials from different sources were significantly different(P<0.05).The content of single element in protein raw materials was significantly higher than that in other raw materials(P<0.05).Through the analysis of the data results,it was beneficial to popularize the application of new protein feed materials and promote the sustainable development of aquaculture in China.
