Comparison Foodlab vs NGD-ISO Methods in Oil Matrices

Neotron, a laboratory certified by ACCREDIA, conducted a study in order to compare the performance of 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 for the determination of Free Fatty Acid
• ISO 3960 for the determination of the Peroxide Value

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: OxiTester, FoodLabFat, PalmoilTester and WineLab.

Neotron drew the following conclusions:

"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."
