摘要
提出了聚酰胺薄膜上分析调味品中苯甲酸的样品处理方法及标准样品加标法。样品在展开剂上行展开10 cm,该方法不需要大型仪器和特殊试剂,适用于多个样品的快速检测,也适用于山梨酸的检测。
A method of sample preparation and preparation of standards by standard addition method for the determination of benzoic acid in flavours was proposed. The chromatography was developed on the polyamide film plate by the linear ascending. The migration distance of solvent was 10 cm. This method has high sample throughput at low operating costs without any large equipment and special reagent. This method is suitable for determination of sorbic acid without modification.
