This document specifies methods of preparing the methyl esters of fatty acids.<\/p>\n

It includes methods for preparing fatty acid methyl esters from animal and vegetable fats and oils, fatty acids and soaps. To cover different requirements, four methylation methods are specified, namely:<\/p>\n

    \n
  1. \n

    a \u201crapid\u201d transmethylation procedure under alkaline conditions;<\/p>\n<\/li>\n

  2. \n

    a \u201cgeneral\u201d transmethylation\/methylation procedure under sequential alkaline and acid conditions;<\/p>\n<\/li>\n

  3. \n

    a BF3<\/sub> transmethylation procedure;<\/p>\n<\/li>\n

  4. \n

    an alternative procedure using acid-catalysed transmethylation of glycerides.<\/p>\n<\/li>\n<\/ol>\n

    Methyl esters so produced are used in various analytical procedures requiring such derivatives, e.g. gas-liquid chromatography (GLC), thin-layer chromatography (TLC) and infrared spectrometry (IR).<\/p>\n

    Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this document.<\/p>\n
