Abstract
Total volatile nitrogen (TVN), ammonia (NH3) and amide‐N were analysed in fish stored without and with preservatives. In well preserved fish the increase in NH3‐N during storage was accompanied by a parallel decrease in amide‐N. It is concluded that NH3 may originate from glutamine and probably also from asparagine. In unpreserved material other sources may dominate.Keywords
