BS EN ISO 11085:2010 Cereals, cereals-based products and animal feeding stuffs. Determination of crude fat and total fat content by the Randall extraction method

BS EN ISO 11085 is an International Standard which specifies procedures for the determination of the fat content of cereals, cerealbased products, and animal feeding stuffs. These procedures are not applicable to oilseeds and oleaginous fruits.

The choice of procedure to be used depends on the nature and composition of the material analysed and the reason for carrying out the analysis.

Procedure A is a method for the determination of directly extractable crude fats, applicable to all materials, except those included within the scope of procedure B.

Procedure B is a method for the determination of total fats, applicable to all materials from which the oils and fats cannot be completely extracted without prior hydrolysis.

Most cereals, as well as feeds of animal origin, yeasts, potato protein, compound feeds with milk products, glutens and products subjected to processes such as extrusion, flaking and heating, yield significantly higher total fat contents when tested by procedure B than by procedure A. See Annex B.
