Innovative CDR Foodlab® Method, fast, user-friendly and realiable simplifies the standard AOCS (Cd 18-90) procedure since permit to test micro-quantities of samples (melted fats or oil as it is) without any treatment in just 2 minutes without toxic reagents, dedicated instrumentation or skilled operator.
CDR FoodLab® method shows a good correlation with AOCS Official Method Cd 18-90
Take a look! It’s fast and simple

Method
Test type: kinetic
Testing time: one test 2 minute – 40 Tests/hour.
Are possible test sessions with several samples, up to a maximum of 16.
The system is supplied pre-calibrated and ready for use.
Calibration Curve / Correlation Data
CDR FoodLab® method shows a good correlation with AOCS Official Method Cd 18-90.
Furthemore Anisidine Value was determined by Campden BRI laboratory using the CDR FoodLab® instrument and the laboratory method Campden BRI Method TES-AC-360: the correlation, R2, was found to be 0.9942 which indicated very good correlation.
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
Anisidine value test is used to assess the secondary oxidation of oil or fat, which is mainly imputable to aldehydes and ketones, and is therefore able to tell the oxidation “history” of an oil or a fat.
Furthermore, AnV analysis on oil is an indicator of excessive oil deterioration in deep frying process.
Reagent test Kits
The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.
This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.
There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
Code. 300503 : 10 tests
Code. 300500 : 100 tests (10 packages of 10 tests)
The reagents have a shelf-life of 12 months.
Sample Handling and Usage of Curves
Sample
Oil as is (extracted from dry fruits, seeds, nuts, etc.).
Solid fats: melted using bain-marie method before starting the test (animal fats, palm oil, etc.)
