Free Fatty Acids in vegetable oil
 |  |
Free Fatty Acids (FFA) value of vegetable oil is determined by the quantity of free fats derived by the hydrolytic rancidity of the triglycerides. This alteration happens when vegetable oil like olive oil, palm oil, avocado oil, palm oil, etc. is not stored or treated correctly; hence, this test gives a fundamental index of the genuineness of the product.
OxiTester enables you to quickly determine the Free Fatty Acid (FFA) value in vegetable oils using innovative method that 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.
Furthermore using OxiTester you can test the acidity of vegetables oils with a system that offers a significantly higher output as compared to commercial olive oil acidity tester in terms of reliability, accuracy, reproducibility, easiness of use and rapidity.
Instrument
Reagents
R (in cuvette): alcohol mixture with potash, phenophtaleine derivative
Test method
Test type: End Point
Colorimetric reaction at 630 nm
Testing time: 1 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.
Sample
Vegetable oil like palm oil, avocado oil, olive oil etc. as is.
Kit
The reagents are provided in sealed bags, each containing 10 test tubes. 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.
