Data on analysis of Brazilian milk powder.

This dataset provides information on the concentration of Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Se, V and Zn, as well as thermogravimetric analysis (TG) and differential scanning calorimetry (DSC) and acid methyl esters (FAMEs) from ten samples of Brazilian powdered milk used in infant feeding. Ten brands of Brazilian companies that sell powdered milk used as food. In detail, the dataset presents: 1- Values of concentrations of Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Se, V and Zn in powder milk were obtained by Inductively coupled plasma-optical emission spectroscopy (ICP-OES) (The file "Table 1 -Raw data on Macro- Microelements" contains the concentration of macro and microelements obtained in ten Brazilian companies) 2- Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) data were performed using thermal analyzer STA 449 F3 Jupter, Netzsch, Selb Alemanha. Graphs were obtained using Universal Analysis Software (The "Raw Thermal Analysis-sample" files contain TG and DSC analysis data from ten Brazilian companies). 3- The fatty acid methyl esters (FAMEs) ere analyzed by gas chromatography (GC 2010, Shimadzu, Kyoto, Japan) to obtain their individual peaks (The "Raw data-fat-composition" files contain FAME analysis data from ten Brazilian companies).

本数据集提供了巴西婴幼儿食用奶粉的10份样品中铝（Al）、砷（As）、钡（Ba）、镉（Cd）、钴（Co）、铬（Cr）、铜（Cu）、铁（Fe）、镁（Mg）、锰（Mn）、钼（Mo）、镍（Ni）、铅（Pb）、硒（Se）、钒（V）及锌（Zn）的浓度信息，同时包含其热重分析（thermogravimetric analysis, TG）、差示扫描量热法（differential scanning calorimetry, DSC）数据与脂肪酸甲酯（fatty acid methyl esters, FAMEs）相关检测结果。本次研究的样品来自巴西本土10家售卖婴幼儿配方奶粉的企业。

数据集具体包含以下内容：
1. 采用电感耦合等离子体发射光谱法（Inductively coupled plasma-optical emission spectroscopy, ICP-OES）测定奶粉中上述宏量与微量元素的浓度，相关原始浓度数据存储于文件"Table 1 -Raw data on Macro- Microelements"中，涵盖10家巴西企业的检测结果。
2. 采用德国耐驰（Netzsch）公司塞尔布（Selb）工厂生产的STA 449 F3 Jupter型热分析仪完成热重分析（TG）与差示扫描量热分析（DSC），并通过Universal Analysis软件生成分析图谱；相关原始热分析数据存储于"Raw Thermal Analysis-sample"文件组中，包含10家巴西企业样品的TG、DSC检测数据。
3. 采用日本京都岛津（Shimadzu）公司GC 2010型气相色谱仪对脂肪酸甲酯（FAMEs）进行分析，得到各组分峰形；相关原始脂肪成分分析数据存储于"Raw data-fat-composition"文件组中，包含10家巴西企业样品的FAME检测数据。
