Oxidation of food grade oils Editor: Dr Matt Miller The PV test is a good way to measure the amount of primary oxidation products in fresh oils. Oils with significant levels of peroxides may still be odourless if secondary oxidation has not begun. If oxidation is more advanced, the PV may be relatively low but the oil will be obviously rancid.
