摘要
目的 评价山东省市售干辣椒和辣椒面中黄曲霉毒素(AFT)的暴露水平及健康风险.方法 采用液相色谱-三重四极杆质谱测定样品中的AFT,点评估方法计算AFT的暴露量.结果 检测的120份干辣椒和辣椒粉中AFTB1的检出率最高,检出率为21.7％(26/120),其中超过国家标准限量的占8.3％(10/120),合格率为91.7％(110/120);AFTB2的检出率次之,检出率为19.2％(23/120);AFTG,的检出率较低,为5.0％(6/120);AFTG2检出率较最低,为0.8％(1/120).辣椒面的检出率高于干辣椒,差异有统计意义(P＜0.05).AFTB,的日膳食暴露量占AFTB,、AFTB2、AFTG1、AFTG2日膳食暴露总量的74.1％,AFTB1膳食暴露导致肝癌发病率为0.001 09/10万人.结论 相关监管部门应加强对辣椒制品仓储环节AFT污染的监测,尤其是根据每个地域温度、湿度不同而制定针对性的措施,最大力度控制AFT污染,为人民健康保驾护航.
Abstract
Objective To evaluate the exposure levels and health risks of aflatoxins(AFT)in dried chili and chili powder sold in Shandong Province.Methods AFT in chili and chili powder samples were determined using liquid chromatography-triple quadrupole mass spectrometry,and aflatoxin exposure was calculated using the point evaluation method.Results The detection rate of AFTB1 was the highest in the 120 samples of dried chili and chili powder investigated,at 21.7％(26/120).The proportion of samples exceeding the national standard limit was 8.3％(10/120);the qualification rate was 91.7％(110/120).The detection rate of AFTB2 was 19.2％(23/120),that of AFTG1 was 5.0％(6/120),and that of AFTG2was 0.8％(1/120).The detection rate of AFT in chili powder was significantly higher than that of dry chili samples(P＜0.05).Daily dietary exposure to AFTB1 accounted for 74.1％of the total daily dietary exposure to AFT.The incidence of liver cancer caused by dietary exposure to AFTB1 was 0.001 09/100 000 people.Conclusion Relevant regulatory departments may strengthen the monitoring of aflatoxin pollution in the storage link of chili products,formulate targeted measures according to the temperatures and humidities in each region,maximize the control of aflatoxin pollution,and protect human health.
