FRAP (Ferric Reducing Antioxidant Power Assay) is a simple rating system of the measurement of antioxidant activity in a honey. Antioxidant activity varies greatly between honeys, meaning not all honeys are the same when it comes to antioxidant properties. At present all food antioxidant activity is measured using tests which measure the antioxidant activity in different ways. FRAP test, makes it much easier for consumers to choose the antioxidant level which suits them.

FRAP assay measures the antioxidant activity in an efficient way. The result is presented in a simplified index system. The scale ranges from 0 – 1000 (ug/100g TE), with 1000 being the highest antioxidant activity.

Acacia honey ranges up to 80 whilst that of Manuka honey can be 300 and Jarrah honey around 600. The majority of Australian honeys are rated at 50 to 800, ​​more than 50 is considerable of high in antioxidants.
