Olive Oil Quality Control
The CDR OxiTester is an olive oil analyser, a simple and reliable system conceived to perform quality controls on olive oil directly at the mill. Tests include free fatty acids (FFA) and peroxide value (PV).
Simple to use, the software guides the user step by step through the tests. Pre-filled reagent vials simplify sample preparation and tests are completed in a few minutes, facilitating real time process adjustments and improving quality control.
Parameters – Free Fatty Acids (FFA), Peroxide Value (PV), Total Polyphenols (Biophenols), Stability Index, K270 and Sugars
Multiple tests for palm oil are also available on the PalmOilTester.
Olive Oil Tests
K270
In addition to providing useful information on the quality of oil and on its degree of oxidation, this test enables identification of rectified oil added to virgin olive oil, by leveraging the fact that mechanically extracted oils do not contain double or triple conjugated bonds that typically form during rectification. Rectified oils therefore exhibit high UV absorbance values, specifically in the 270 nm region, which are significantly higher as compared to those of virgin and extra virgin oils. The greater absorption in the 270 nm region, during the most advanced oxidation stages, is determined also by the formation of ketone groups.
Sugars
Glucose and fructose can give an important indication for the olive maturation. By determining the amount of total fermentable sugar, the sum of glucose and fructose, it is possible to assess the correct period for harvesting.

Acidity
The free acidity content of an oil is given by the free fatty acids derived from hydrolisis (rancidification) of triglycerids. This process takes place whenever the oil is treated or stored in non-optimal conditions. The acidity represents therefore a fundamental indicator of the product quality, and is used to define its merceological classification in accordance with the European regulations.
Peroxides
The peroxide number of an oil describes its primary oxidation state and, therefore, its tendency to become rancid. A lower number of peroxides indicates a good quality of oil and a good preservation status. Unsaturated fatty acids react with oxygen to form peroxides, which trigger a series of chain reactions terminating with the production of volatile compounds with the characteristic rancid smell. These reactions are accelerated by higher temperatures as well as by exposure to light and oxygen. The lower the peroxide number, the higher is the oil quality and its conservation state.
Total Polyphenols
Polyphenols are among the most precious components of olive oil. They are the source of its characteristic fruity taste and its sharp, tangy bite. They protect the oil from becoming rancid and possess a powerful antioxidant action on the organism. The polyphenols have a protective action not only on oil but also on cells of the human body because they oppose the negative effects of free radicals. The amount of polyphenols decreases during oil extraction so the test can be used to optimize the processing. The total polyphenol content of an oil depends on its cultivar variety, the harvest period, soil characteristics and extraction process. The higher the polyphenol concentration, the longer it lasts and the greater its beneficial health effects.
Stability Index
Oxidative stability represents the resistance of the oil to oxidation and rancidification, and is therefore linked to its lasting freshness. CDR OxiTester method is a valid alternative to the reference Rancimat method, as was demonstrated by a study from University of Athens published in an important scientific paper. Oxidative Stability analysis is performed indirectly with the CDR OxiTester method through the analysis of Total Polyphenol contents, which can be performed in drastically shorter times than the reference Rancimat method.

How It Works
Multitiple Sample Analysis
Multitiple Parameter Analysis
Features
Innovative Technology
The use of innovative photometric technology means the reading cell guarantees high sensitivity, a very wide measuring range and excellent repeatability of the analysis results thanks to innovative LED light sources with fixed wavelengths (ultraviolet – visible spectrum, power up to 6 O.D.).
Online Help
The system is easy and intuitive, everyone can use it. Analyses are carried out in just a few steps. In addition, it has a help function that guides you step by step through the test procedures.
Multitasking Mode
The multitasking mode reduces analysis time by making it possible to perform several analyses of the same sample simultaneously, or different determinations of the same parameter on a batch of different samples. During an analysis session you can start another one and put the first one in the background. You can return to background analysis with one click.
Internal Memory
The analyser is equipped with an internal memory capable of storing thousands of analysis results that can be viewed on the display or exported via the USB or Ethernet port.
Barcode/QR Code Reader
The analyser connects with barcode or QR code readers. The sample code is automatically displayed on the analyser. It is possible to associate all the analyses performed on that sample.
PC/Intranet Connection
You can share analysis results by connecting the analyser to your intranet via the Ethernet port or export them by connecting the analyser via the USB port to a host computer.
Maintenance/Service Free
No calibration is necessary because the instrument is supplied pre-calibrated. The analysers use LED light sources and therefore no periodic maintenance is required.
