Iodine represents a fundamental element for human health, with particular regard to thyroid function. Dietary intake of milk naturally rich in iodine becomes of primary importance in the prevention of syndromes related to iodine deficiency. The concentration of iodine in milk is characterized by wide variability, mainly related to animal feed and level of mineral supplementation. Therefore, there is interest in the development of fast analytical techniques which are able to predict milk iodine concentration. The aim of the present study was to investigate the effectiveness of energy-dispersive X-ray fluorescence (ED-XRF) for the prediction of iodine in cow milk. Results showed moderate accuracy of the ED-XRF technique, with a coefficient of determination in cross validation of 0.60. This study represents a first contribution towards the possibility to discriminate milk with high or low iodine concentration, as an essential preliminary step for the introduction into the market of naturally fortified milk.
碘是人体健康的基本要素，尤其对甲状腺功能至关重要。富含碘的牛奶的膳食摄入量对于预防与碘缺乏有关的综合征至关重要。牛奶中碘的浓度具有很大的可变性，主要与动物饲料和矿物质补充水平有关。因此，人们对能够预测牛奶碘浓度的快速分析技术产生了兴趣。本研究旨在探讨能量色散 X 射线荧光（ED-XRF）在预测牛奶碘含量方面的有效性。结果表明，ED-XRF 技术具有中等的准确性，交叉验证的决定系数为 0.60。本研究首次为鉴别高碘和低碘牛奶提供了一种可能性，这是将富含碘的牛奶引入市场的重要初步步骤。
