利用高效液相色谱丹磺酰氯柱前衍生法,检测了从新疆自治区4个县市采集的44个熏马肠中8种生物胺含量。结果显示:4.6%熏马肠样品的生物胺(BAs)总量超过FDA规定的1 000 mg/kg限量标准,色胺、酪胺和亚精胺含量在不同程度上超过生物胺安全用量标准,腐胺和尸胺含量与国外报道基本一致。

A high-performance liquid chromatographic(HPLC) derivatized with dns-cl chloride method was developed for the determination of eight biogenic amines in smoked horse intestines from different countries in Xinjiang.The result showed that BAs content was higher than FDA standard in about 4.6% of the samples.The contents of tyramine,tryptamine,and spermidine were more than the standard of safety content in different extent.The contents of putrescine and cadaverine were consistent with that reported by investigators from other countries.
