苦荞茶中黄曲霉毒素B_1的风险评估研究

Study on Risk Assessment of Flavonoids B_1 in Tartary Buckwheat Tea

根据凉山州第一人民医院提供的1 643份普格县乙肝五项血清检验报告,计算出凉山州普格县HBV感染率及乙肝发病率。采用酶联免疫法对凉山州150份苦荞茶样品进行黄曲霉毒素含量检测,结果显示:213个样品中的黄曲霉毒素含量平均值为6.148μg/kg,标准偏差为3.298 1。模拟计算出高、中、低摄入水平人群通过食用苦荞而引发乙肝的最高风险为0.001518,远远小于凉山州目前的43.82%的乙肝发病率;引发肝癌的风险为9.152×10^(-3)例/10万人口远远小于全国目前每年89.00例/10万人的肝癌发病率,表明目前苦荞中的黄曲霉毒素对我国居民产生的健康风险较低。

According to the five serological test reports of hepatitis B in Puge county provided by the first people＇s Hospital of Liangshan State, the infection rate of HBV and the incidence rate of hepatitis B in Puge County of Liangshan State were calculated. The content of aflatoxin in 150 samples of Tartary buckwheat tea in Liangshan state was determined by enzyme-linked immunosorbent assay. The results showed that the average content of aflatoxin in 213 samples was 6.148 μg/kg and the standard deviation was 3.2981. The highest risk of hepatitis B caused by consumption of Tartary buckwheat in people with high, middle and low intake level was 0.001518 less than that of 43.82% in Liangshan Prefecture. The risk of causing liver cancer is 9.152×10^-3 cases/10 thousand population, which is far less than the incidence of liver cancer of 89.00/10 thousand people per year in China, which indicates that aflatoxin in Tartary buckwheat has a lower health risk to Chinese residents at present.
