CDR PalmOilTester: The analysis system of raw and refined palm oil, easy to use and reliable in results

Analysis of the Free Fatty Acids on Palm oil

With the method developed by CDR laboratories, it is possible to easily analyse the Free Fatty Acids (FFA) of raw and refined palm oil in less than 1 minute at all stages of its production, in analysis laboratories or on the processing lines of food industries that use it as an ingredient. The CDR method simplifies and speeds up the official procedure, the results are correlated with the reference methods AOCS/ISO.


Principle of the test

The fatty acids in the sample, under conditions of pH < 7.0, react with a chromogen to develop a colour whose optical density, measured at 630nm, is proportional to the concentration of acidity of the fat, expressed as % of oleic acid.

Correlation curve with reference methods

The CDR FoodLab® method for determining the Free Fatty Acids content of oils and fats, which is used by CDR PalmOilTester, has shown an excellent correlation with the AOCS Official Method Ca 5a-40. In addition, the international reference laboratory Campden BRI carried out comparative tests between the CDR method and the titration method used by Campden BRI laboratories (Campden BRI Method TES-AC-211 based on ISO 660 or AOCS Cd 3d-63 or AOCS Ca 5a-40 or AOAC 940.28): the correlation coefficient R2 was 0.9834, a value that shows a very good correlation between the two methods.
