中文摘要:

      目的 对我国标准人经食用油脂及加工食品摄入反式脂肪酸进行风险评价。方法 采用气相色谱法检测食用油脂及加工食品中反式脂肪酸的含量, 运用Crystal Ball软件对食用油脂和加工食品中反式脂肪酸的风险商(hazard quotient, HQ)进行分析和风险描述。结果 食用油脂的HQ平均值为1.21E-1, 90百分位概率下风险商为3.07E-1(HQ<1), 95百分位概率下风险商为3.33E-1(HQ<1); 含油脂高的加工食品HQ平均值为5.30E-1, 90百分位概率下风险商为9.59 E-1(HQ<1), 95百分位概率下风险商为1.92E 0(HQ>1)。结论 郑州市居民经食用油脂摄入反式脂肪酸的风险较低(HQ<1); 摄入含油脂高的加工食品的90百分位的概率下不存在风险(HQ<1), 95百分位暴露水平下存在一定的风险性(HQ>1)。

英文摘要:

      Objective To assess the risk of standard person of trans-fatty acids (TFA) by edible oils and fats and processed foods in China. Methods The content of TFA of edible oils and fats and processed foods were determined by gas chromatographic method. The hazard quotient (HQ) value and risk description of TFA that Chinese residents intake through the edible oils and fats and processed foods were analyzed by the Crystal Ball software. Results The average HQ value was 1.21E-1, with the 90 percentage of 3.07E-1(HQ<1) and the 95 percentage of 3.33E-1(HQ<1) in edible oils and fats. The average HQ value was 5.30E-1, with the 90 per-centage of 9.59 E-1(HQ<1) and the 95 percentage 1.92E 0(HQ>1) in the processed foods contained higher fat. Conclusion It is not risk of residents intake trans-fatty acid through the edible oils and fats and 90% prob-ability processed food (HQ<1), but it is risk through the processed foods containing high fat at the 95% expo-sure levels (HQ>1).
