目的了解成都市新都区市售辣椒粉中黄曲霉毒素B1(AFB1)的污染现状,为辣椒粉中AFB1污染水平的监测提供基础数据。方法于2015年3月和6月分层抽样共采集80份散装辣椒粉样品,用酶联免疫吸附法(ELISA)测定AFB1含量。结果所采集的80份辣椒样品AFB1检出率为93.8%,超标率为7.5%,轻度污染率为86.3%。3月采集的样品受AFB1污染水平较高于6月所采样品,其中3月采集的样品有1份AFB1含量达到12.24μg/kg,为限量标准5μg/kg的2.5倍。结论为了保障人民的健康,建议开展辣椒粉AFB1日常监测。
Objective To understand the status of aflatoxin B1 (AFB1) pollution in the market of paprika in Xindu District of Chengdu City, and provide the basic data for monitoring the level of AFB1 pollution in paprika. Methods A total of 80 samples of bulk chili powder were collected by stratified sampling in March and June 2015, and the content of AFB1 was determined by enzyme-linked immunosorbent assay (ELISA). Results The detection rate of AFB1 was 93.8% in 80 pepper samples collected, the exceeding standard rate was 7.5% and the mild pollution rate was 86.3%. The samples collected in March were more contaminated by AFB1 than those collected in June. Among them, 1 sample collected in March had an AFB1 content of 12.24 μg / kg, 2.5 times of the standard 5 μg / kg. Conclusion In order to protect people’s health, daily routine testing of paprika AFB1 is recommended.
