✦ Synopsis

A simple and canvenient procedure based on resersed-phase paper and thlnlayer chromatography is reported for the detection and estinrztion of N-nitrosamines in food products, particuIarPy cured meat. The method can easily be applied in tropic& regions when plenty of sunshine is available. It is particularly useful in faod-testing laboratories where sophisticated analytical instruments such as the gas chromatograph, mass spectrometer, etc., are not avallabfe. By this procedure, it is possible to detect up to tC@g and to estimate up to 75+g (reversed phase) and SO,t(g (thin layer) amounts of N-nitrosamines.

N-Nitrosamines are formed during the curing of meat xv&h nitrites and nitrates. Recently, there has been some concern that nitrosamines are highly toxic when ingested in certain concentrations I+_ Manv widely used agricultura! chemicals
