Test Biofuel and Biodiesel Oils
The CDR FoodLab measures FFA, IV and PV
Test Free Fatty Acids (FFA), Iodine Value (IV and Peroxide Value (PV)
Rapid, simplified alternative test method
Quick, accurate, no calibration or maintenance required
Validated alternative to reference or titration methods
Oils for use in Biofuels and Biodiesel
The CDR FoodLab allows simple, accurate tests to be carried out on oils for evaluating key parameters, ensuring FFA, PV and IV levels are not elevated, The analyser represents an improvement over the standard titration methods being fasetr, less hazourdous and using significantly less sample volumes. The CDR FoodLab test results show excellent correlation with the reference methods.
- Faster test results
- No solvent waste disposal costs
- No external lab fees
Parameters – Free Fatty Acids (FFA), Peroxide Value (PV), Iodine Value (IV)
Free Fatty Acids
Free fatty acids (FFAs) are created when a fatty acid chain is cleaved from its parent fat molecule. The level of FFAs is dependent on temperature, moisture content and time. They also will vary depending on how the fat/oil is stored, processed or heated. When fatty acids cleave from their parent molecule and become an FFA, they are much less stable and more prone to oxidation.
How The FoodLab Measures Free Fatty Acids
Free fatty acids of a sample, at pH <7.0, react with a chromogenous compound and decrease in colour. The decrease of colour, read at 630nm, is proportional to the acid concentration of the sample, expressed as % of oleic acid.

Iodine Value
The most important application of the iodine number is to determine the amount of unsaturation contained in the fatty acids that make up oils. This unsaturation is in the form of double bonds which react with iodine compounds. The higher the iodine value, the greater the unsaturation present in the fatty acid. The iodine number is used as a quality or process control parameter, but it can also be used as a characterization parameter because each type of oil or fat has an iodine value included in a range that identifies the product itself.
How the FoodLab Measures Iodine Value
Double bonds react with iodine in alcoholic solution determining a variation in the reagent’s absorbance. This amount measured at 446 nm is indirectly related to the concentration of double bond in the sample, expressed as IV.
Peroxide Value
Peroxides are a result of primary oxidation in oil and are defined as the amount of peroxide oxygen per 1 kg of fat/oil. Peroxides are very unstable and can easily develop into aldehydes..
How the FoodLab Measures Peroxide Value
R-O-O-R peroxides oxidize Fe2+ ions. The Fe3+ ions resulting from oxidation are grouped and form a red complex. Its colorimetric intensity, measured at 505nm, is directly proportional to the concentration of peroxides in the sample. Results are expressed as meqO2/Kg.

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.
