Resumen:
This international standard enables 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 requires 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 will also oxidise other 3-hydroxysterols. The method is technically equivalent to IUPAC method 2.404 Determination of total sterol content.
