Abstract

The invention discloses a UPLC-MS / MS detection method of eight biogenic amines in Baijiu. The eight biogenic amines such as putrescine, cadaverine, histamine, tyramine, phenylethylamine, spermidine, tryptamine and spermine in the Baijiu can be qualitatively and quantitatively analyzed at the same time. The UPLC-MS / MS detection method of the eight biogenic amines in the Baijiu, disclosed by the invention, has the advantages that pretreatment is simple and derivatization is not needed; a linear correlation coefficient is greater than 0.99, the recovery rate is 80 to 120 percent and the relativestandard deviation is within 10 percent, which shows that the method disclosed by the invention can be applied to quantitative analysis of the eight biogenic amines in the Baijiu.

Description

technical field [0001] The invention relates to a UPLC-MS / MS detection method for eight biogenic amines in liquor, belonging to the field of liquor detection and analysis. Background technique [0002] Biogenic amines are a class of nitrogen-containing aliphatic (putrescine, cadaverine, spermine, spermidine), aromatic (tyramine, phenylethylamine) or heterocyclic (histamine, tryptamine) low molecular weight compounds. It is mainly formed through the deshuttle of amino acids or the amination and transamination of aldehydes and ketones. It has important physiological effects on the active cells of animals, plants and microorganisms. An appropriate amount of biogenic amines contributes to the normal physiological functions of the human body, and excessive amounts will cause It causes adverse physiological reactions, which can lead to increased blood pressure, headache, flushing, and rash; sometimes it is mainly gastrointestinal dysfunction, including sudden vomiting and diarrhea...
