Analysis of the Acidity of Olive Oil

With the method devised by the CDR laboratories, it is possible to easily analyze the acidity of olive oil and extra virgin olive oil in a crusher in 1 minute, along the production line of an oil mill, upon acceptance or during the sales phase. The CDR method simplifies and speeds up the official procedure and the results are aligned to the ISO reference method.

Analyzers to test Acidity (FFA) in Olive Oil 

You can determine the percentage of acidity of olive oil with the CDR OxiTester, a tool for the analysis of olive oil of the CDR FoodLab® line available in 2 versions, CDR OxiTester and CDR OxiTester Junior.

Method

End point test.
Test time: 1 minute.
It is possible to perform several test sessions with a maximum of 16 samples.

Principle of the test

The fatty acids of the sample, under conditions of pH <7.0, react with a chromogen, developing a color whose optical density, measured at 630 nm, is proportional to the concentration of the fatty acid, expressed as % of oleic acid.

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 *300128/A: 10 test.

Code *300125/A: 100 test (10 buste da 10 test)

For samples, with high acidity, where a dilution is requested, you must use an appropriate reagent kits.

Code. 300129: 100 tests.

The reagents have a shelf-life of 12 months.
