Popis:	N-Nitrosodimethylamine (NDMA) in beer has been traced to direct-fired malt. This study separated and quantified the malt alkaloids-methyltyramine as well as the suspected precursors, hordenine and gramine. However, laboratory nitrosation of malt samples resulted in hordenine accounting for only minor amounts of NDMA and gramine, almost none. Thus, a large portion of NDMA in malt must be due to one or more other precursors. Studies indicate that dimethylamine may be a likely candidate
