3 MCPDE & GE Mitigation Technology

Process description

Palm oil is one of the most widely used vegetable oils in the world. If global trends are any indication, the demand is only rising, but at the same time, this oil is the subject of debate. Fatty acid esters such as 3 MCPDE (3-monochloropropane1,2-diol esters) and GE (Glycidyl esters) are present in all kinds of fats and oils. Palm oil, however, exhibits these esters in excessively high quantities, requiring their removal of as they are suspected carcinogens.

3 MCPDE formation takes place due to the presence of chlorides,mono and diglycerides as well as process parameters including high temperatures, processing time (harvest to refining) and the acidic value of oils. Glycidyl esters (GE) are formed due to the processing of food items at high temperatures and the processing timeline at high temperatures. GEs form as a result of high temperature deodorization and the presence of a higher amount of FFAs. One method used to reduce the formation of 3 MCPDE is to reduce contact with chloride ions. GE formation can be mitigated using various solutions for refining applications. However, attaining the lowest possible value of 3 MCPDE and GE requires additional processes to be followed.

Kumar offers solutions for both oil millers as well as refiners to mitigate the formation of 3 MCPDE and GE in the output oil.
