Antioxidant Capacity

Antioxidant capacity is an overall ability of organisms or food to catch free radicals and prevent their harmful effect.
There are three different ways to determine the antioxidant capacity:

Colorimetric methods, which measure the ability of an antioxidant to reduce an oxidant, with a change of color.
Fluorimetric methods, which measure the ability of an antioxidant to eliminate free radicals through the donation of a hydrogen atom.
Electrochemistry methods, which the sample is oxidized by applying a variable potential. A variable voltage is applied to the strip to “activate” the antioxidants, so they cede the electrons. Electrons are released and detected as a current at the electrode.
