Abstract

Analysis of aflatoxin B1 (AFB1), B2 (AFB2), G1 (AFG1) and G2 (AFG2) in 76 edible oil samples (peanut oil, soybean oil, corn embryo oil and blended oil) was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The oils were sampled from three areas (Shijiazhuang, Baoding and Tangshan) of Hebei Province of China. AFB1 was detected in 22 samples representing 28.9%, followed by AFB2 (7.89%) and AFG1 (3.95%), while no AFG2 contamination was detected in any samples. AFB1 levels in oil samples ranged 0.14-2.72 µg kg(-1) and AFB2 ranged 0.15-0.36 µg kg(-1), while lower levels of 0.01-0.02 µg kg(-1) for AFG1 were recorded. The paper is part of an on-going investigation of aflatoxin contamination in Chinese edible oils.

摘要

采用液相色谱-串联质谱法（LC-MS/MS）对76份食用油样品（花生油、大豆油、玉米胚芽油和调和油）中的黄曲霉毒素B1（AFB1）、B2（AFB2）、G1（AFG1）和G2（AFG2）进行了分析。这些油样取自中国河北省的三个地区（石家庄、保定和唐山）。在22份样品中检测到AFB1，占比28.9%，其次是AFB2（7.89%）和AFG1（3.95%），而在任何样品中均未检测到AFG2污染。油样中AFB1的含量范围为0.14 - 2.72 μg kg⁻¹，AFB2为0.15 - 0.36 μg kg⁻¹，而AFG1的含量较低，为0.01 - 0.02 μg kg⁻¹。本文是对中国食用油中黄曲霉毒素污染正在进行调查的一部分。
