ʻO Nitrosamine kekahi o nā carcinogens ʻekolu i ʻike ʻia ma ka honua, ʻo nā mea ʻelua ʻelua he aflatoxins a me benzo[a]pyrene.Hoʻokumu ʻia ka Nitrosamine e ka nitrite a me ka amine lua i loko o ka protein a ua hoʻolaha nui ʻia ma ke ʻano. ʻO ka nitrite a me ka nitrate nā paʻakai maʻamau maʻamau i ka ʻai ʻana i kēlā me kēia lā a me ka wai inu.ʻO ka Nitrate a me ka nitrite ka pollutants ionic ma GB 2762-2017 i kapa ʻia "National Food Safety Standard -Limit of pollutants in food".ʻO GB 5009.33-2016 ka inoa "National Food Safety Standards for the Determination of Nitrite and Nitrate in Food" e hoʻohālikelike i ka hoʻoholo ʻana o kēia mau mea ʻelua, a me ka chromatography ion e like me ke ʻano mua i hoʻokomo ʻia i ka maʻamau.
Hoʻomaʻamaʻa mua ʻia nā laʻana e like me GB / T 5009.33, a ma hope o ka ua ʻana o ka protein a me ka lawe ʻana i ka momona, lawe ʻia nā laʻana a hoʻomaʻemaʻe ʻia e nā ʻano like.Ke hoʻohana nei i ka CIC-D160 ion chromatograph, SH-AC-5 anion column, 10.0 mM NaOH eluent a me ka bipolar pulse conductance method, ma lalo o nā kūlana chromatographic i ʻōlelo ʻia, penei ka chromatogram.
