| 摘 要： | 利用植物乳杆菌（ATCC8014）对泛酸的含量在一定条件下成线性关系，通过吸光度测定细菌繁殖浓度，可间接测定食物样品中泛酸的含量，并检测其回收率。结果表明标准曲线在10—100ng范围内线性关系良好，批内相对标准差（RSD）为2．1％-4．3％，批间测定RSD为2．7％-4．1％，回收率为88．4％～100．5％，达到了较好的分析效果。

| Abstract: | The growth of Lactobacillus plantamn(ATCC 8014) and the pantothetic acid content in the solution shows a linear relationship.Pantothetic acid content in food can be measured by absorbency of bacterial solution after a certain period of time.The standard curve reflected good linear relationship in the range of 10-100 ng.The inter-batch RSD was between 2.1% and 4.3%,and the intra-batch RSD between 2.7% and 4.1%.The rate of recovery was between 88.4% and 100.5%. |
