中文摘要：黄曲霉毒素B1（AFB1），在婴儿食品中发现的一种有毒的真菌代谢物，会给儿童的健康带来严重的并发症。本研究用配备了柱后光化学衍生仪及荧光检测器的高效液相色谱系统，调查了在伊朗市场可购买的48种婴儿食品中AFB1存在的情况。研究发现婴儿谷物食品中，AFB1存在的比率及含量都很高，表明需要减少这些产品中AFB1的污染。因此，有必要对收割前后、储存及加工过程进行进一步监控。
外文摘要：BACKGROUNDAflatoxin B1 (AFB1), a toxic fungal metabolite that is found in baby foods, can lead to serious complications for children's health. In the present study, 48 commercial baby foods available in the Iranian market were investigated for the presence of AFB1 using a high performance liquid chromatography system that was equipped with post-column photochemical derivatization and a fluorescence detector. RESULTSThirty-three out of 48 samples (68.7%) were contaminated with AFB1 at median, maximum and mean concentration levels of 0.11, 15.15 and 2.602 ± 4.065 µg kg−1, respectively. The AFB1 concentration in 39.6% of the samples was higher than the maximum level established in Iran for AFB1 within baby foods containing milk (0.5 µg kg−1). The incidence of AFB1 in rice, wheat and multigrain infant cereal samples was 90%, 25% and 100%, respectively, whereas rice-based baby foods contained the highest levels of AFB1. CONCLUSIONIn the present study, the finding of both high rates and high levels of AFB1 in cereal baby foods indicates the need to reduce AFB1 contamination in these products. Therefore, further monitoring and control of pre- and post-harvest, storage, and manufacturing processes is required.
