ISO 2002-11 16
]]> ISO/TS 17764-2:2002 specifies the application of gas chromatography with capillary columns and flame ionization detection for the determination of the quantitative content of fatty acids in a fat by making use of the methyl esters of the fatty acids obtained in accordance with the method specified in ISO/TS 17764-1:2002.

ISO/TS 17764-2:2002 is applicable to the investigation of animal and vegetable fats, oils and fatty acid mixtures for incorporation in animal feeding stuffs and fat extracts of animal feeding stuffs and raw materials for compound animal feeds, including fats and fatty acid mixtures containing butyric acid.

This method is not applicable to polymerized fatty acids.

ISO 2002-11 12
]]> ISO/TS 17764-1:2002 specifies two methods for preparing the methyl esters of fatty acids of animal and vegetable fats, oils and fatty acid mixtures for raw materials for compound animal feeds, and fatty acids originating from fat extracts of animal feeding stuffs, including fats and fatty acid mixtures containing butyric acid.

The general method, the boron trifluoride (BF3) method is concerned with the preparation of methyl esters of fatty acids with six or more C atoms, originating from fats, oils and free fatty acids.

The KOH/HCl method is concerned with the preparation of methyl esters of fatty acids with four or more C atoms. This method can also be used for the quantitative determination of fatty acids with a chain length shorter than 10 C atoms in free fatty acid mixtures.

The methyl esters produced can be used for gas-liquid chromatography (GLC).

Unsaponifiable materials are not removed and can, when present in considerable amounts, interfere with the chromatographic analysis.

ISO 2000-08 14
]]> This International Standard specifies a calibration method and a standard addition method for the determination of

potassium and sodium contents of animal feeding stuffs by flame-emission spectrometry.

The standard addition method applies if it is not known whether the emissions measured for potassium or sodium

are subject to matrix effects. The limit of determination for potassium and sodium is 0,04 g/kg.

The calibration method applies if such matrix effects have been shown to be absent.

Published By Publication Date Number of Pages
ISO 2002-04 12
]]> This International Standard specifies a qualitative method for the determination of zearalenone in animal feeding

stuffs and, in particular, in maize. This method is for screening purposes only.

The limit of determination of zearalenone is approximately 50 µg/kg .

NOTE Although sorghum gives interfering fluorescent spots identical to those of zearalenone, the method is still applicable to this

feed because Rf the values are different after development of the chromatogram in the second direction. These spots are not

developed by the specified confirmation technique.
