Technical Reports

GOED and its Technical Committee have developed guidelines for handling oxidation challenges in the processing of omega-3 oils, which can be accessed below. These are best practices and are not meant to replace the oxidation limits in the GOED Voluntary Monograph. 


This industry advisory outlines the correct way to express the content of EPA, DHA, and fatty acid content in omega-3 oils.

[GOED Reported Levels 2018 10 05] The levels of 2-MCPD, 3-MPCD, their esters, and glycidyl esters in distinct lots from GOED members. Updated October 5, 2018.


Provision of Information on the Levels of 2-MCPD, 3-MCPD, Their Esters, and Glycidyl Esters in EPA/DHA-Rich Oils (Fish Body Oils, Fish Liver Oils, and Concentrates) Updated July 17, 2017.



The following is a white paper co-authored in 2013 by GOED and GOED member Nutrasource.

The AOCS (American Oil Chemists’ Society) and GOED jointly run the GOED Nutraceutical Oils laboratory proficiency program. This program allows companies to compare their lab's proficiency at measuring oxidation and fatty acid profiles in EPA/DHA oils to other labs in the industry.  

Any company with a lab that does fatty acid analysis is eligible to participate. Once a company enrolls in the program, they receive two mailings with three oil samples each (six total per year) to analyze. After the results from all participating labs are submitted to AOCS, they are compiled and companies receive a report comparing their results to the average results from all the other labs.
