title: [Determination of epsilon-caprolactam in food media by thin-layer chromatography].
abstract: 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.
