In recent years, the occurrence of nitrosamine, which are produced by the interaction of nitrite and secondary amine, in foods has been the subject of considerable interest and controversy. In this experiment, changes in nitrate, nitrite, TMAO, TMA and DMA nitrogen of salted and dried corvenia, which were incorporated with sodium benzoate, ascorbic acid, cysteine and tetracycline in salt, during processing and storage were analyzed. Levels of nitrate nitrogen was decreased while those of nitrite was increased in salted and dried products during processing and storage, but sample was incorporated with ascorbic acid, cysteine and sodium benzoate in salt inhibited the reduction of nitrate to nitrite while with tetracycline in salt accelerated this reduction in salted and dried products during processing and storage. Contents of TMAO nitrogen in all salted and dried products as well as in the control was decreased, but was increased during storage, while TMA nitrogen was increased in salted and dried products during processing and storage. Contents of DMA nitrogen was increased in all salted and dried products during processing and storage, DMA contents of raw in the control was increased to more than 11.6 times after storage for 30 days, but sample was incorporated with ascorbic acid, cysteine and sodium benzoate in salt inhibited the production of DMA nitrogen while with tetracycline in salt accelerated in salted and dried products during processing and storage.
