Scope

This International Standard specifies the determination of the absolute value of diacylglycerols as well as 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 catalyzed reaction.

The mass fraction of 1,2-diacylglycerols can be used as a quality criterion for vegetable fats and oils.

The absolute content of diacylglycerol can be used as authenticity criterion for vegetable fats and oils.Note: Results obtained using this International Standard have not been compared with results obtained using ISO 29822 Part 1.
