[N-nitrosamines in beer and nonalcoholic beverages]

The content of carcinogenic N-nitrosamines was examined in beer, kvas, kvas wort, in dried pear and drink prepared from the dried fruit. An analysis was made with the use of the fluorescence technique. It was found that only some of the beer grades contain a negligible amount of N-nitrosamines. The remaining products showed no N-nitrosamines.
