Abstract
By extraction of acidified aqueous extracts of malt with organic solvents, methylation of the resulting extracts, gas chromatography and detection with a nitrosamine-specific detector, it is shown that N-nitrosoproline is present in malt and that N-nitrososarcosine is sometimes present. N-Nitrosopipecolinic acid has not been observed.Keywords
