Free Fatty acids (FFA) in oils and fats
 |  |  |
You can determine in 1 minute the Free Fatty Acid (FFA) value in edible fats and oils using innovative CDR FoodLab method that simplifies and speeds up the AOCS procedure with the same accuracy.
CDR FoodLab method for the determination of Acidity (FFA) is implemented in FoodLab, FoodLabFat and PalmOilTester.
The acid content of oils and fats is given by the quantity of free fatty acids deriving from the hydrolytic rancidity of triglycerides.This alteration happens when the edible fats are not stored or treated correctly; hence, this test gives a fundamental index of the genuineness of the product.
The acidity of crude oil is a very important parameter in that it determines the quality of a vegetable oil (like palm oil) from the very initial production stages within the oil mill.
Furthermore, acidity test is particularly important during the refining of oils and fats, for the assessment of the processing cycle and for the definition of product categories.
the CDR FoodLab method enables you to carry out a FFA analysis using micro-quantities of sample and can be applied even to fat substances that have a difficult extraction process.
Features and benefits of Free Fatty Acid CDR FoodLab method
- Test results are available in 1 minute.
- Faster and easier method than official AOCS method.
- Thanks to its high accuracy and sensitivity, up to 0.01% deviation in oleic acid can be detected.
- Unlike NIR systems, it does not require complicated calibration.

Instrument
FoodLab
FoodLabFat
PalmOilTester
Reagents
R (in cuvette): alcohol mixture with potash, phenophtaleine derivative
Test method
Test type: End Point
Colorimetric reaction at 630 nm
Testing time: 3-6 minutes
It is possible to carry out several test sessions with a maximum of 14 samples.
Calibration can be performed by aligning the test to reference values.
Test principle
Sample fatty acids, at a pH < 7.0, react with a chromogen developing a colour with an optical density that, if measured at 630 nm, is proportional to the concentration of the fatty acid, expressed as percentage of oleic acid. CDR innovative method simplifies and speeds up the standard procedure. It is possible to carry out a test using micro-quantities of sample and can be applied even to fat substances that have a difficult extraction process.
Sample
Oil as is (extracted from olive, seeds, nuts, etc.).
Solid fats: melted using bain-marie method before starting the test (animal fats, palm oil, etc.).
Extractable fats: extract the fatty part following the instructions provided in the test method (butter, cream, margarine, semi-finished products, etc.).
Kit
The reagents are provided in sealed bags, each containing 10 cuvettes. They have a 12 months duration, starting from the production date. Stocking requirements are described on the bag label.
Reagents do not contain dangerous solvents and are ready for use.
