The objective of the study was to assess selenium and other elements levels in Indian Roti bread from Se-rich maize and rice using inductively coupled plasma mass-spectrometry. Se levels in Roti bread from Se-rich maize and rice exceeded those in the control samples by a factor of more than 594 and 156, respectively. Using Se-enriched maize increased bread Co, Cr, Mn, Mo, and Zn content, whereas Fe and I levels were reduced. In Se-rich rice-based bread a decrease in Co, Cr, Cu, Fe, I, Mo, and Zn contents was observed. Daily consumption of Se-rich maize and rice bread (100 g) could account for 5.665% and 4.309% from recommended dietary allowance, also exceeding the upper tolerable levels by a factor of 7.8 and 5.9, respectively. Therefore, Roti bread from both Se-rich maize and rice may be considered as an additional source of selenium. At the same time, regular intake of Se-rich grains and its products including breads may cause adverse health effects even after a few days and should be regularly monitored in order to prevent Se overload and toxicity.
本研究的目的是使用电感耦合等离子体质谱法评估富硒玉米和大米制成的印度烤饼中的硒及其他元素含量。富硒玉米和大米制成的烤饼中的硒含量分别比对照样品高出594倍和156倍以上。使用富硒玉米会增加烤饼中钴、铬、锰、钼和锌的含量，而铁和碘的含量则会降低。在富硒大米制成的烤饼中，钴、铬、铜、铁、碘、钼和锌的含量均有所下降。每日食用富硒玉米和大米烤饼（100克）分别可提供推荐膳食摄入量的5.665%和4.309%，也分别超出可耐受最高摄入量7.8倍和5.9倍。因此，富硒玉米和大米制成的烤饼都可被视为额外的硒来源。同时，即使仅食用几天后，经常摄入富硒谷物及其制品（包括面包）也可能对健康产生不良影响，应定期进行监测，以防止硒摄入过量和中毒。
