Abstract：In order to evaluate the effect of ingredients and processing stages on the contents of N-nitrosamines in stuffed fish roll, changes in the contents of 9 volatile N-nitrosamines, nitrite, thiobarbituric acid reaction substances (TBARs) and total volatile nitrogen (TVB-N) were measured during the processing of stuffed fish roll (filling and skin). The results showed that TVB-N value decreased while TBARs and nitrite contents increased during processing for both fish roll filling and skin. The various ingredients used in fish roll filling contained different levels of N-nitrosodimethylamine (NDMA, 0–27.51 μg/kg), N-nitrosodiethylamine (NDEA, 0?3.39 μg/kg), N-nitrosoethylmethylamine (NMEA, 0.11?4.33 μg/kg) and N-nitrosodiphenylamine (NDPheA, 0?0.82 μg/kg). NDEA (0?12.56 μg/kg), NMEA (0.08?15.26 μg/kg) and N-nitrosopiperidine (NPIP, 0?8.13 μg/kg) were detected in the ingredients of the fish roll skin. NDMA, NMEA and NDEA in filling as well as NDMA and NDMA in skin were mainly formed during chopping, and their contents decreased with the addition of other ingredients at the later stage of processing. NDPheA and NPIP were lower than the detection limit during the processing of filling and skin. The final product contained (1.9 ± 0.2) μg/kg of NDMA in filling, which was lower than the national standard limit, and NDMA was not detected in skin.
