The occurrence and levels of nitrofuran metabolites (NFMs) in sea cucumber (SC) from Dalian, China, are reported. Four metabolites including 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), 3-amino-2-oxazolidinone (AOZ), semicarbazide (SEM) and 1-aminohydantoin (AHD) in different SC products (fresh, instant and dry salted SCs) were measured. The frequency of occurrence for NFMs in all SC samples was 42.7%. The total NFM concentrations ranged from non-detectable to 64.6 ng g, with a mean of 3.59 ng g. AOZ and SEM were the dominant congeners, accounting for 40.1% and 59.1% of the total NFMs, respectively. The concentrations and patterns varied among different regions. Higher levels of NFMs were found in the fresh SC products, and the order for the average concentration of ∑NFM was fresh > dry salted > instant.
本文报道了中国大连海参中硝基呋喃代谢物（NFMs）的存在情况和含量水平。测定了不同海参产品（鲜海参、即食海参和干腌海参）中的四种代谢物，包括3-氨基-5-吗啉甲基-2-恶唑烷酮（AMOZ）、3-氨基-2-恶唑烷酮（AOZ）、氨基脲（SEM）和1-氨基乙内酰脲（AHD）。所有海参样品中NFMs的检出频率为42.7%。NFMs的总浓度范围为未检出至64.6 ng/g，平均浓度为3.59 ng/g。AOZ和SEM是主要的同系物，分别占总NFMs的40.1%和59.1%。不同地区的浓度和模式有所不同。鲜海参产品中NFMs的含量较高，∑NFM平均浓度的顺序为鲜海参＞干腌海参＞即食海参。
