Analysis, distribution, and health evaluation of 8 biogenic amines in Chinese mackerel products by CoFe2O4/MEG solid phase extraction-HPLC

A CoFe 2 O 4 /MEG solid-phase extraction combined with high performance liquid chromatography was used for determination of 8 biogenic amines (Bas) in canned Spanish mackerel products. A new comprehensive evaluation system, including dietary exposure, food safety index, chemical quality index and biogenic amine index, was used for investigating the pollution distribution, exposure and health assessment of BAs in four sea areas/provinces of China. The pollution levels in the Yellow Sea-Jiangsu, Bohai Sea-Shandong, Yellow and Bohai Sea-Liaoning regions were equivalent, with ∑8BAs equalling 34.7–36.5 mg/kg, while in the South China Sea-Guangdong region ∑8BAs was lowest at 18.9 mg/kg. The concentration range of ∑8BAs and ∑4BAs were ND (not detected)-113 mg/kg and ND-80.8 mg/kg, respectively. All results showed that the main components of BAs were putrescine, histamine, and spermine, with detection rates ranging from 23.1% to 42.3%. The dietary exposure level range of 8 BAs was 85.8–266 μg∙kg −1 ∙d −1 , IFSc was 0.00800–0.0248, CQI values range in the four regions was 1.21–3.93, with a mean CQI of 1.98. The total value of BAI ranges ND-0.840 mg/kg, with a mean BAI of 20.3 mg/kg. Statistical analysis showed that the overall health risk of BAs exhibits different trends in terms of gender, age, and region.
