摘  要:
将面粉中过氧化苯甲酰转变为苯甲酸,然后用气相色谱法按苯甲酸定量。结果表明:线性范围在0~200μg/ml之间,相关系数为0.9998,回收率在84.3%~108%。此方法简便、快速、准确,是测定面粉中过氧化苯甲酰含量的行之有效的方法。

摘  要:
The benzoyl peroxide in wheat flour was changed into benzioc acid. Benzioc acid was analyzed by gas chromatography method. Such results showed that the calibration curve was in linear relationshipin the range of 0~200μg/ml, whereas the correlation coefficient was 0.9998. The recovery rate was 84.3%~108%. This method was simple、fast and accurate. It was a good way to assay the concentration of benzoy1 peroxide in wheat flour.
