Vegetable fats and oils — Isomeric diacylglycerols — Part 1: Determination of relative amounts of 1,2- and 1,3-diacylglycerols

General information

Current stage: 40.99 Effective date: 7 korr 2026

Originator: ISO

Owner: ISO/TC 34/SC 11

Type: International Standard

Scope

ISO 29822:2009 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.
