摘要
为给小麦粉质量安全检测提供本底值判断依据,本实验使用电感耦合等离子体原子发射光谱(ICP-AES)法测定了2012年我国不同区域种植的492份自磨小麦粉的硼含量,旨在为小麦粉质量安全检测提供本底值判断依据。结果表明:492份自磨小麦粉硼元素的本底值平均为0.648mg/kg,变幅为0.2401.361mg/kg,符合正态分布,95%概率条件下的置信区间值为0.261-1.035mg/kg,置信区问最大值1.035mg/kg,可作为运用ICP-AES法时所有小麦粉样品的硼元素本底值。
Boron background values in foods are important to judge the proper amount of borax or boric acid. A total of 492 flour samples milled from wheat collected from different growing areas in China during the crop year 2012 were determined by ICP-AES for boron content. The average background value of boron in these wheat flour samples was 0.648 mg/kg and the variation range was 0.240-1.361 mg/kg, following normal distribution. The 95% confidence interval for the wheat flour samples was 0.261-1.035 mg/kg, whereas the maximum confidence value was 1.035 mg/kg. Accordingly the data obtained in this study can be seen as background values of boron element in wheat flour samples.
