Abstract
For the determination of Patulin in apple juice a method of analysis was developed permitting the detection of 40 microng Patulin/kg apple juice. With additions between 120--200 microng Patulin/kg the recovery rates lie between 82 and 90%. After a pre-purification of the crude extract by liquid-liquid extraction and column-chromatography the Patulin is determined thinlayer chromatographically by reflectance measurement at 273 nm.
摘要
为测定苹果汁中的展青霉素，开发了一种分析方法，该方法可检测出每千克苹果汁中40微克的展青霉素。当展青霉素添加量为每千克120 - 200微克时，回收率在82%至90%之间。通过液 - 液萃取和柱色谱对粗提物进行预纯化后，采用薄层色谱法在273纳米处通过反射率测量来测定展青霉素。
