영어 초록
The study was focused to investigate the effect of nitrosodimethylamine (NDMA) formation due to nitrosamine (NA) precursor and/or inhibitor addition to Kimchi during the fermentation of Kimchi at room temperature (16±2℃). The addition of nitrite and dimethylamine (DMA) to Kimchi showed the average 32-fold (21.3-113.9 ug/kg) and 9-fold (1.3-40.3 ug/kg) higher NDMA formation than control (0-5.6 ug/kg), respectively. Also, the addition of both nitrite and DMA resulted in the increase of NDMA formation to average 42-fold (39.4-155.7 ug/ kg) higher than control. On the other hand, the addition of 4 mM ascorbic acid to Kimchi with nitrite and DMA inhibited the formation of NDMA down to 71.3% of control. However, the addition of cysteine and erythorbic acid affected no inhibition to NDMA formation during the test. The addition of sodium sulfite increased NDMA formation. Accordingly, this showed that the amount of ascorbic acid generated during Kimchi fermentation played an important inhibition role for NA formation.
