ISO 12966-3:2016 sp\u00e9cifie une m\u00e9thode de transest\u00e9rification rapide des corps gras par catalyse basique avec de l'hydroxyde de trim\u00e9thylsulfonium (TMSH), pour pr\u00e9parer des esters m\u00e9thyliques d'acides gras. Cette m\u00e9thode s'applique exclusivement \u00e0 la pr\u00e9paration des esters m\u00e9thyliques des corps gras pour l'analyse chromatographique en phase gazeuse-liquide (CPG). Elle s'applique \u00e0 tous les corps gras, \u00e0 l'exclusion de ceux issus du lait et des produits laitiers. L'isom\u00e9risation des acides gras insatur\u00e9s ne se produit que rarement et les acides gras isom\u00e9ris\u00e9s ne sont pr\u00e9sents que dans la limite de d\u00e9termination. Puisqu'il y a isom\u00e9risation, ce mode op\u00e9ratoire n'est pas recommand\u00e9 pour l'acide linol\u00e9ique conjugu\u00e9 (CLA).<\/p>\n

Seulement environ 70 % \u00e0 80 % des acides gras libres sont est\u00e9rifi\u00e9s. Dans le cas d'acides gras conjugu\u00e9s cyclopropyl et cycloprop\u00e9nyl, des r\u00e9actions secondaires peuvent se produire mais n'interf\u00e8rent pas dans la d\u00e9termination des acides gras.<\/p>\n","protected":false},"excerpt":{"rendered":"
