The results showed that whether a compound exhibited antioxidant or pro-oxidant behavior depended on its polarity, concentration, oxidation time and the method used to determine lipid oxidation.
The most commonly used additives for this purpose are stearate complexes of transition metals such as zinc, silver, cobalt, copper, nickel, manganese, and chromium as well as alkaline earth metals such as magnesium and calcium [13-16], More recently, Contat-Rodrigo [17] reported that the transition metal carboxylate-based pro-oxidant promoted the abiotic oxidation of PP during UV-irradiation and the level of oxidation in UV-aged PP samples depended on the amount of pro-oxidant.
