New European standard for determination of crude fat and total fat content in cereals, cereal based products and animal feed stuffs

An ISO standard developed on the basis of the FOSS Soxtec system and an associated application note has also been approved as a European standard.

The previously published ISO 11085:2008 “Cereals, cereal based products and animal feeding stuffs – Determination of crude fat and total fat content by the Randall extraction method” was approved by the CEN member states in July.

The approval as a European standard has positive implications for trade. A common standard for crude and total fat can now be used for labeling purposes for cereals (food & feed), cereal based products and animal feedstuffs. The standard has the potential for worldwide recognition pending an ongoing review by the AOAC.

The ISO 11085 2008 standard was developed to reflect progress made within fat and total fat analysis and has now replaced the ISO 7302 standard which was more cumbersome to apply.

SoxCap validation study

A report on a validation study for the FOSS SoxCap™ system is available using the article download button on this page. The report gives details about how the FOSS SoxCap system was validated against the ISO 11085 standard by an international inter-laboratory test running the same samples simultaneously with the ISO 11085 validation study.

More information

The new EN ISO 11085:2008 standard will soon be published and will be available for order via www.iso.org or national standardization bodies.

A paper describing the use of the SoxCap in connection with the ISO 11085 standard was published in the FOSS In Focus magazine, no. 1, 2007 and can be downloaded here (links to a pdf article 250 kb).
