Determination of 3-MCPD, 2-MCPD and Glycidol in oil and fat by ISO 18363-4 Zwagerman/Overman
Author(s)GERSTEL
Fully automated method for 3-MCPD, 2-MCPD and Glycidol determination in Edible Oil and Fat based on ISO 18363-4 - Zwagerman/Overman with validation data. A recent upgrade to PTV injection has further improved the quality and robustness of results. Fatty acid esters of 3- and 2-monochloropropanediol (3-MCPD-e, 2-MCPD-e) and glycidol (Gly-e) are process contaminants that are formed, for example, when edible oils and fats are refined. After ester cleavage during digestion in the human body they pose a relevant health risk and therefore need to be determined in edible oils and fats and in fat containing food.
