Palm Oil Tester

PalmOil Tester: analyzer for crude and refined palm oil

PalmOil Tester is a simple and accurate testing system that, within a few minutes, enables to determine Free Fatty Acid (FFA), Peroxide Value (PV), DOBI,  Iodine Value, Anisidine Value (AnV) & Carotene in raw and refined palm oil.

Thanks to its simplicity and reliability, PalmOil Tester is used by palm oil producers in Malaysia, Thailand, Indonesian, Nigeria etc. during all production stages: in the oil mills where the fruit is crushed, in refineries, during acceptance, during storage and when the finished product is sold.

The innovative characteristics have made PalmOil Tester very popular among worldwide food industries that use palm oil as ingredient.

The System

The analytical system includes:

  • A Photometric Analyzer with solid state emitters (LEDs) and reading and incubation cells thermostated at 37° C.
  • A Kit of pre-vialed, disposable reagents with a low toxicity developed by the research laboratories of CDR and a 12-month shelf-life.
  • Pipettes to simplify the collection of the samples.
  • Print Manager: software that enables the connection of the analyzer to the PC in order to store and print the results of the tests.
  • Operator’s manual and functional illustrated sheets.


 The Analysis

PalmOil Tester is able to test raw palm oil and Kernel Palm Oil and provides the following information:

This system significantly reduces testing time because it enables to test up to 16 samples simultaneously, which means that it is possible to perform 80 FFA tests, 70 Peroxide Value tests, 40 Iodine Value tests and 40 p-Anisidine Value tests in an hour.2

Simple Methods

PalmOilTester analytical methods are simpler and faster as compared to traditional ones. Tests can be performed in a few simple steps:

  1. Heat the palm oil, which is solid at room temperature.
  2. Select the parameter to measure from the menu: the system automatically selects the correct wavelength.
  3. Use the supplied pipette to add the correct volume of reagent and sample, then mix.
  4. Follow the displayed instructions.
  5. The result is automatically calculated in a few minutes, displayed and printed by means of the on-board printer.

No Technical Support and Maintenance Expenses

  • Unlike NIR systems or other photometric systems, this system does not require regular calibrations: it is supplied pre-calibrated, although the calibration parameters can be changed quickly and simply.
  • The system does not require costly spare parts: the analyser uses LED luminous sources and does not therefore require the maintenance that is usually needed for photometers with tungsten luminous filaments. The absence of moving parts eliminates the risk of damages.

In Line with Reference Methods

PalmOilTester and its analytical methods have been subjected to comparative tests by several agencies like Indelab sdn. Bhd. Malaysia, Member Analyst to FOSFA INTERNATIONAL. Tests have demonstrated a good alignment with official AOACS methods.

Solid Documentation

PalmOilTester is supplied with a DVD that contains videos of the methods, which are useful to learn quickly how to perform the tests and obtain the most accurate results.
