摘　　要：本文采用液相色谱法测定了33个杏仁样品中的本底苯甲酸含量,结果表明,苯甲酸的检出率为100%,含量为0.0065~0.3867 g·kg^(-1),均值为0.0967 g·kg^(-1),含量不超过0.3013 g·kg^(-1)的概率为95%,表明在杏仁中存在天然苯甲酸,为零添加杏仁制品的检验判定、市场监管和标准制修订提供了基础数据。In this paper,the content of benzoic acid in 33 almond samples was determined by liquid chromatography.The results showed that the detection rate of benzoic acid was 100%,the content was 0.0065~0.3867 g·kg^(-1),the average value was 0.0967 g·kg^(-1),and the probability that the content was not more than 0.3013 g·kg^(-1) was 95%.The results indicated that there existed natural benzoic acid in almond,which provided basic data for the inspection and judgment,market supervision and standard revision of almond products without additive.
