目的了解湖北省市售坚果及籽类制品中4种黄曲霉毒素的污染状况。方法采用高效液相色谱法对湖北省9个地市州的市售9种坚果及籽类制品中4种黄曲霉毒素的含量进行测定。结果采集样品256份,黄曲霉毒素B1、B2、G1、G2的检出率分别为76.17%、25.00%、62.11%、17.97%,4种毒素的检出率比较差异有统计学意义(χ2=247.393,P<0.05),黄曲霉毒素B1的超标率为1.95%,黄曲霉毒素B2、G1、G2因无国家限量标准故不予评价;各地市州之间黄曲霉毒素的检出率比较差异无统计学意义(χ2=11.773,P>0.05);在监测的9类坚果及籽类样品中,其检出率比较差异无统计学意义(χ2=12.941,P>0.05)。结论湖北省坚果及籽类制品中存在黄曲霉毒素污染的现象,污染以AFB1为主,应引起相关部门的重视,并强化日常监督。
Objective To understand the contamination status of four kinds of aflatoxins in commercially available nuts and seeds in Hubei Province. Methods The contents of four aflatoxins in 9 kinds of nuts and seeds in 9 prefectures and cities in Hubei Province were determined by high performance liquid chromatography. Results The detection rate of aflatoxins B1, B2, G1 and G2 were 76.17%, 25.00%, 62.11% and 17.97%, respectively. The detection rates of four toxins were statistically significant (χ2 = 247.393, P <0.05), aflatoxin B1 exceeded the standard rate of 1.95%, aflatoxin B2, G1, G2 because there is no national limit standards so evaluation; Aflatoxins around the city of the detection rate was significantly different There was no significant difference (χ2 = 11.773, P> 0.05). There was no significant difference in the detection rate among the 9 types of nuts and seeds (χ2 = 12.941, P> 0.05). Conclusion The aflatoxin contamination exists in the nuts and seeds of Hubei Province. The main pollution is AFB1, which should be paid more attention by relevant departments and should be strengthened daily supervision.
