醬腌菜作為老百姓日常生活中經(jīng)常食用的開胃小菜,由于各種原因其中容易產(chǎn)生亞硝酸鹽的累積,而亞硝酸鹽對人體又有著各種危害.因此,在醬腌菜生產(chǎn)和監(jiān)管中,對亞硝酸鹽的檢測顯得尤為重要

As a common appetizer in daily life, pickled vegetables are prone to accumulate nitrite due to various reasons, which poses various hazards to the human body. Therefore, in the production and supervision of pickled vegetables, the detection of nitrite is particularly important
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., under acidic conditions, sodium cyclohexylaminosulfonate and sodium nitrite react to form cyclohexanol. Under acidic conditions, cyclohexanol continues to undergo esterification reaction with sodium nitrite to form cyclohexene, which becomes gaseous at room temperature. Quantitative detection is carried out using a headspace gas phase injection system. Calculate the nitrite content in pickled vegetable embryos based on the proportional relationship between the response value of cyclohexene chromatography and the concentration of nitrite.
