Abstract:

Mycotoxins are low-molecular-weight secondary metabolites produced by different fungal species, which can cause teratogenic, hepatotoxic, nephrotoxic, carcinogenic, hemorrhagic, and immunosuppressive effects, and damage the reproductive system in humans and other mammals. Mycotoxins are often present at low concentrations in the matrices and present a branch of compounds, homologs, and isomers. Vegetable oil is one of the top mycotoxin-contaminated foods. Vegetable oil contains lipids, fatty acids, and pigments, which have the potential to increase matrix effects and damage instruments. Therefore, the establishment of high-efficient sample pretreatment methods, and highly sensitive and high-throughput detection techniques are big challenges for the accurate determination of various mycotoxins in vegetable oil. In the present study, the current status and development trends of mycotoxin detection methods in different vegetable oils have been reviewed. Different pretreatment methods such as liquid-liquid extraction, solid phase extraction, gel permeation chromatography, dynamic covalent hydrazine chemistry, and QuEChERS are also summarized. Additionally, characteristics of detection techniques such as gas chromatography, liquid chromatography, tandem mass spectrometry, and immunosensors are discussed.
