The method for thin-layer chromatography has been developed for determination of epsilon-caprolactam in food media: fats, dry products. The method sensitivity is 0.01 mg/kg (mg/1) for fats and 0,005 mg/kg for dry products. The method error is 20%. epsilon-Caprolactam was extracted from fats by water, from dry products by ethyl alcohol. The extracts were evaporated and chromatographed in a thin layer of silica gel. epsilon-Caprolactam was determined on the plates from the spot area. The method was used for hygienic evaluation of polyamide-6 film intended for packing fats and dry products.
已开发出用于测定食品介质（脂肪、干燥产品）中ε-己内酰胺的薄层色谱法。该方法对脂肪的灵敏度为0.01毫克/千克（毫克/升），对干燥产品为0.005毫克/千克。方法误差为20%。ε-己内酰胺从脂肪中用水萃取，从干燥产品中用乙醇萃取。萃取液蒸发后在硅胶薄层上进行色谱分析。根据斑点面积在板上测定ε-己内酰胺。该方法用于对包装脂肪和干燥产品的聚酰胺-6薄膜进行卫生评估。
