ISO 11702:2009 Animal and vegetable fats and oils - Enzymatic determination of total sterols content
standard by International Organization for Standardization, 12/01/2009
More info
Full Description
ISO 11702:2009 specifies a method for the quantitative determination of the total sterols content by means of an enzymatic staining test. The method is applicable to free and esterified sterols in animal and vegetable fats and oils, fatty foods and related products. The determination is applicable to sample quantities of 1 g to 2 g of fat.
The method is not applicable to dark coloured fats and oils, e.g. crude palm oil. The enzyme is not specific for cholesterol, but also oxidizes other 3-hydroxysterols. The method has not been tested for products fortified with sterols at higher levels.
