With regard to the formation of carcinogenic dimethylnitrosamine (DMNA) in a salted Alaska pollock roe, the effects of the co-existing substances, especially hemoglobin (Hb) and ascorbate, on the formation of DMNA by the reaction between dimethylamine (DMA) and nitrite were investigated.Apparently, the blood and Hb of carp revealed an accelerative effect on the formation of DMNA when they were added to Alaska pollock roe or to minced halibut flesh together with DMA and nitrite.The addition of ascorbate to Alaska pollock roe or to halibut flesh, both containing DMA, nitrite and Hb, resulted in a considerable decrease of the amount of DMNA being formed. However, in the flesh sample without Hb, ascorbate caused no change in DMNA production.The authors concluded that the “inhibitive activity” of ascorbate mentioned above might be regarded as the inhibition of the “accelerative activity” exhibited by Hb, rather than of the reaction between DMA and nitrite.
