title: Differential-pulse polarographic determination of N-nitrosoproline in uncooked meat.
abstract: Ham and bacon have been analysed for N-nitrosoproline by differential-pulse polarography. Quantitative polarograms without interfering peaks were obtained from ethanol extracts prepared after extensive clean-up which included freeze-drying and column chromatography. Differential-pulse polarography proved sufficiently sensitive to give peaks corresponding to ca. 100 mug of N-nitrosoproline per kg in several commercial samples of cured meat.
