This document specifies a method to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME). The total glycerol content is then calculated from the obtained results.<\/p>\n

Under the conditions described, the quantification limits are 0,001 % (m<\/i>\/m<\/i>) for free glycerol, 0,10 % (m<\/i>\/m<\/i>) for all glycerides (mono-, di- and tri-). This method is suitable for FAME prepared from rapeseed, sunflower, soybean, palm, animal oils and fats and mixture of them. It is not suitable for FAME produced from or containing coconut and palm kernel oils derivatives because of overlapping of different glyceride peaks.<\/p>\n

\n NOTE 1\n <\/div>\n

For the purposes of this document, the term \u201c% ( m<\/i>\/ m<\/i>)\u201d is used to represent the mass fraction.<\/p>\n<\/div>\n

\n
\n NOTE 2\n <\/div>\n

Under the common EN 14105 GC<\/span><\/span> conditions squalene can coelute with alpha glycerol monostearate. If the presence of squalene is suspected, EN 17057<\/span><\/span> can be used to discriminate between squalene and glycerol monostearate.<\/p>\n<\/div>\n
