p-Anisidine Value (AnV) test in Fats and Oils

CDR FoodLab, the fats and oils chemical analysis system for quality and process controlseither in a laboratory or on the production line
 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

Calibration Curve / Correlation Data

CDR FoodLab® method shows a good correlation with AOCS Official Method Cd 18-90.

good correlation between CDR FoodLab methond and 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.

Anisidine Value method comparison: CDR FoodLab® method vs Reference method

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.)

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
