Tierische und pflanzliche Fette und Öle - Enzymatische Bestimmung des Gesamtsterin-Gehaltes (ISO 11702:2016); Deutsche Fassung EN ISO 11702:2016
Overview
This International Standard 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. 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. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this International Standard. The International Standard has been prepared by ISO/TC 34/SC 11 "Animal and vegetable fats and oils" (secretariat: BSI, United Kingdom) of Technical Committee ISO/TC 34 "Food products" (secretariat: AFNOR, France). CEN/TC 307 "Oilseeds, vegetable and animal fats and oils and their by-products - Sampling and test methods" (secretariat: AFNOR, France) is responsible for the European Standard. On the national level, "Gemeinschaftsausschuss für die Analytik von Fetten, Ölen, Fettprodukten, verwandten Stoffen und Rohstoffen" (GA Fett) ("Joint Committee for the analysis of fats, oil, fat products, related substances and raw materials") of the German Society for Fat Science (DGF) and DIN Standards Committee Food and Agricultural Products (NAL) is responsible for the standard.
