- the presence of 3-MCPD esters in all refined vegetable oils and fats
- palm oil does not contain the highest level of 3-MCPD esters in comparison with other oils as reported by some researchers
- health risk posed by MCPD esters is also ambiguous
- no toxicological data on 3-MCPD esters are available
- the cause of formation of 3-MCPD esters are deodorising temperature in refining process, pH and chloride content (nature of the chloride ion)
- limit of detection (LOD) is 0.25 miligram/kg, while limit of quantification (LOQ) is 0.5 miligram/kg
- the possible factors that contribute to the formation of 3-MCPD esters besides the deodorisation are - acidity (dosage of phosphoric acid), type of bleaching earth (natural versus acid activated), chloride levels
The level of 3-MCPD esters in the processed palm oil can be reduced if the following measures are taken ;
- the ffb should be harvested and sterilised immediately
- natural clay and acid-activated clay with neutral or close to neutral pH are recommended during refining
- optimisation of phosphoric acid dosage during degumming
- reduction of acidity prior to bleaching
- chemical refining is a possible way to reduce the formation of 3-MCPD esters
- ensuring good quality CPO
