 ISO NP 20948: Animal and vegetable fats and oils — Determination of aflatoxin B1, B2, G1, G2 in vegetable oils by high performance liquid chromatography and immunoaffinity column cleanup

ISO NP 20948 was cancelled in March 2019 due to lack of progress. Subsequent collaboration with AOAC as well as support by a new member body (SAC) and project leadership to develop the method was established. The NWIP Ballot was therefore initiated to re-establish the project and was approved (N 1554) in Sept 2020. The AOAC method needs revision and updating to include international validation data as well as to extend to other oil types.

The SAC mirror Committee on Oils and Fats is therefore calling for participants for a collaborative study to provide international validation data on additional oil types. The project, in brief, will entail the following:

• Pre-trial:             Four test samples are expected to be dispatched by February 2021.  Results are to be reported within two week after sample arrival.
• Main trial:          Either 32 or 34 test samples (depending on availability) to be dispatched by June 2021 to conduct the main test.  Each sample is to be analysed for AFTB1, AFTB2, AFTG1 and AFTG2.  Results are to be reported by July 2021.

Laboratories who are interested in taking part in the international validation of this method should contact Project Leader, Ping Jing, at jingdaping@126.com by latest 30 December 2020.
