The aim of this study was to determine the influence of freezing and the most often used functional additives such as: sodium chloride, sodium nitrite, polyphosphates, and sodium ascorbateon in the nitrozamine content in cured pork and beef. The nitrozamines (dimethylnitrozamine DMNA, diethyl-nitrozamine DENA) were extracted from raw material, distilled concentrated in a vacuum and determined by gas chromatography according to the Pancholy method. The study showed that the addition of sodium chloride in the form of brine to meat caused a decrease in the content of short chain nitrozamines, i.e.: DMNA and DENA. During the curing of meat with nitrite the content of the nitrozamine increased as compared to the raw meat without additives. The concentration of the nitrozamines in meat can be significantly reduced through the addition of sodium ascorbate. The freezing itself has little influence on the nitrozamine content in meat.
