Subject(s): In: Journal of the Science of Food and Agriculture United Kingdom : Society of Chemical Industry ; John Wiley & Sons, 1979. v. 30, no. 8, p. 795-798Summary: A method for the analysis of the lysine content of feedstuffs employing acid hydrolysis followed by enzymic decarboxylation of lysine and subsequent gas-liquid chromatographic (g.l.c.) analysis of the cadaverine produced, is described. The method is relatively rapid and a comparison of the results from a wide range of feedstuffs analyzed by g.l.c. and by conventional ion-exchange chromatography gave confidence in the method.
