Minerals multi-element analysis and its relationship with geographical origin of artisanal Mexican goat cheeses

Abstract The objective of this study was to perform a profile of mineral elements and the relationship of those as markers of geographical origin of artisanal goat cheese from the State of Veracruz, Mexico. In fresh and mature goat cheeses the quantified elements were: heavy (aluminum, arsenic, cadmium, lead), major (calcium, potassium, sodium, magnesium), essential (cobalt, chromium, copper, iron, manganese, selenium, zinc), and others (nickel and strontium). The database using variance analyses and discriminant function analysis was analyzed. Differences (P < 0.05) were found in the contents of elements between fresh and mature cheeses. The content of major, essential and other elements were similar to the results from other investigations. The concentration of arsenic and lead surpassed the limits accepted by international and Mexican standards. Nine elements helped to determine the geographic origin of the goat cheeses.摘要 本研究旨在对墨西哥韦拉克鲁斯州手工山羊奶酪开展矿物元素特征谱分析，并探究这些元素作为地理来源标志物的关联。针对新鲜与成熟山羊奶酪，本次定量检测的元素类别包括：重金属（铝、砷、镉、铅）、常量元素（钙、钾、钠、镁）、必需元素（钴、铬、铜、铁、锰、硒、锌）及其他元素（镍与锶）。本研究采用方差分析与判别函数分析法对该数据集进行了分析。结果显示，新鲜与成熟山羊奶酪的元素含量存在显著差异（P < 0.05）。常量元素、必需元素及其他元素的含量与其他同类研究结果基本一致。砷与铅的浓度超出了国际及墨西哥相关标准所允许的限值。最终筛选出9种元素，可用于确定该手工山羊奶酪的地理来源。
