Overview

This International Standard specifies the determination of the degree of isomerization of diacylglycerols in vegetable fats and oils. 1,2-Diacylglycerols are transformed to the more stable 1,3-isomers during storage or due to acidic catalysed reaction. The mass fraction of 1,2-diacylglycerols can be used as a quality criterion for vegetable fats and oils. The International Standard has been prepared by ISO/TC 34/SC 11 "Animal and vegetable fats and oils" (secretariat: BSI, United Kingdom). The responsible body for the European Standard is CEN/TC 307 "Oil seeds, vegetable and animal fats and oils and their by-products - Methods of sampling and analysis" (secretariat: AFNOR, France). On the national level, the standard is supervised by NA 057-05-05 AA "Gemeinschaftsausschuss für die Analytik von fetten, Ölen, Fettprodukten, verwandten Stoffen und Rohstoffen" (GA Fett) of the German Fat Research Society (DGF) ("Joint committee for the analysis of fats, oils and products thereof, related and primary products") and NAL.
