Les proc\u00e9d\u00e9s modernes de traitement des aliments ne permettent pas d\u2019\u00e9liminer compl\u00e8tement ces compos\u00e9s. Des protocoles de surveillance stricts ont donc \u00e9t\u00e9 mis en place. Id\u00e9alement, une m\u00e9thode universelle d\u2019analyse des mycotoxines permettrait un \u00ab screening \u00bb tr\u00e8s efficace. Une telle m\u00e9thode est cependant tr\u00e8s compliqu\u00e9e \u00e0 d\u00e9velopper, en raison des diff\u00e9rences entre les propri\u00e9t\u00e9s physico-chimiques des mycotoxines, de l\u2019efficacit\u00e9 de l\u2019extraction et des effets de matrice. Zhang et al. a ont publi\u00e9 une \u00e9tude impliquant plusieurs laboratoires [1] dans le but de proposer aux laboratoires une m\u00e9thode d\u2019analyse qui pourrait \u00eatre largement appliqu\u00e9e \u00e0 l\u2019analyse de diverses mycotoxines dans un grand nombre de matrices. Nous nous sommes inspir\u00e9s de ces travaux pour d\u00e9velopper la m\u00e9thode LC-MS\/MS ci-apr\u00e8s qui permet de s\u00e9parer 12 mycotoxines r\u00e9glement\u00e9es par la FDA dans les limites de pression des instruments HPLC classiques.<\/p>\n\n\n\n<p>Dans cet exemple, les mycotoxines ont \u00e9t\u00e9 analys\u00e9es dans une matrice de poudre de cacahu\u00e8te. L\u2019utilisation d\u2019une colonne relativement courte, la s\u00e9lectivit\u00e9 de la phase Biphenyl stationnaire et l\u2019efficacit\u00e9 des particules de 2,7 \u03bcm \u00e0 surface poreuse des colonnes Raptor ont permis d\u2019excellentes s\u00e9parations dans le cadre d\u2019une analyse rapide de 5 minutes 30 (dur\u00e9e totale du cycle : 7 minutes). La mycotoxine HT-2 co\u00e9luant avec un compos\u00e9 de matrice partageant la m\u00eame transition MRM (447.3-285.3) la plus abondante, une transition moins abondante (447.3-345.3) a \u00e9t\u00e9 choisie pour l\u2019analyse quantitative. Un tampon ammonium a \u00e9t\u00e9 utilis\u00e9 afin de favoriser l\u2019ionisation des mycotoxines et augmenter ainsi la sensibilit\u00e9. La colonne Raptor Biphenyl a donn\u00e9 d\u2019excellents r\u00e9sultats pour les 12 mycotoxines \u00e9tudi\u00e9es dans les travaux cit\u00e9s, mais pour des listes plus longues de compos\u00e9s contenant des mycotoxines isobariques de structure similaire, la phase Raptor FluoroPhenyl peut constituer un meilleur choix. La s\u00e9lectivit\u00e9 de la colonne Raptor Fluorophenyl est mise en \u00e9vidence dans notre&nbsp;<a href=\"https:\/\/discover.restek.com\/articles\/ffss2790\/highly-selective-lc-msms-analysis-of-mycotoxins-from-multiple-classes\" data-type=\"post\" data-id=\"43565\">analyse de 20 mycotoxines<\/a>.<\/p>\n\n\n\n<p>La m\u00e9thode d\u00e9crite ici s\u2019est r\u00e9v\u00e9l\u00e9e extr\u00eamement pr\u00e9cise pour les 12 mycotoxines r\u00e9glement\u00e9es par la FDA qui ont \u00e9t\u00e9 \u00e9valu\u00e9es lors d\u2019une \u00e9tude de validation couvrant un certain nombre de matrices (y compris plusieurs sources de semoule de ma\u00efs et de farine de riz brun, en plus de l\u2019exemple de la poudre de cacahu\u00e8te pr\u00e9sent\u00e9 ici).
