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

p-Anisidine Value (AnV) test in Palm oil

Anisidine value test is used to assess the secondary oxidation of oil, which is mainly imputable to aldehydes and ketones, and is therefore able to tell the oxidation "history" of an oil.
Furthermore, AnV analysis on oil is an indicator of excessive oil deterioration in deep frying process.

Method

Test type: kinetic

Test time: 1 minute.

Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR PalmOilTester.

Sample treatment

Solid samples at room temperature must be melted before being analysed. The sample must be collected when the oil is consistently melted and still warm.

Principle of the test

Aldehydes, derived from the secondary oxidation of fat matrix, react with the p-anisidine determining a variation in the absorbance, measured at 366 nm. Anisidine value is expressed as AnV (Anisidine value) following AOCS (Cd 18-90) the reference method.

Calibration curve

CDR method shows a good correlation with Campden BRI laboratory method (Campden BRI Method TES-AC-360).
