Neotron, an accredited laboratory, conducted a study in order to compare the performance of CDR FoodLab® ’s method with NGD and ISO methods used to determine the level of soaps, Peroxide Value (PV) and Free Fatty Acid (FFA) in an oil matrices.
Reference methods are:
- NGD C8 – 1976 for the determination of soaps
- ISO 660 (AOCS Cd 3d-63 or AOCS Ca 5a-40 or AOAC 940.28) for the determination of Free Fatty Acid
- ISO 3960 (AOCS Cd 8b-90 or AOAC 965.33 ) for the determination of the Peroxide Value
CDR FoodLab® ’s method used to determine the Free Fatty Acid (FFA), Peroxide Value (PV) and soaps in oils and fats is available also in the following systems: CDR OxiTester, CDR FoodLab®, CDR PalmoilTester and CDR WineLab®.

Neotron drew the following conclusions:
“CDR FoodLab® is easy to use. The tests performed in relation to Peroxide Value (PV), Free Fatty Acid (FFA) and soaps confirm that the system provides an excellent photometric linearity and that the results are equivalent to those obtained during parallel tests based on ISO methods (for the Peroxide Value (PV) and Free Fatty Acid (FFA)) and the NGD methods (for soaps). The ISO methods used to determine the Peroxide Value (PV) and Free Fatty Acid (FFA) match the analytical criteria defined for these parameters in EEC Regulation 2568/91 and subsequent amendments.“
