Antioxidants have thus attracted much interest of the food scientists, medical and nutritional experts as well as the general public. The term antioxidants is defined as substances that when present in foods at low concentrations compared to that of an oxidizable substrate markedly delay or prevent the oxidation of the substrate (7). Antioxidants that fit in this definition include free radical scavengers, reducing agents, inactivators of peroxides and other reactive oxygen species (ROS), chelators of metals, and quenchers of secondary lipid oxidation products that produce rancid odors (2).
It must, however, be noted that alkenal and alkadienals also react with the T B A reagent and produce a pink color. Thus the term thiobarbituric acid reactive substances (TBARS) is now used instead of MA. The T B A test is used frequently to assess the oxidative state of a variety of food systems, despite its limitations such as lack of specificity and sensitivity (40). As already noted, many other substances may react with the T B A reagent and contribute to absorption, causing an overestimation of the intensity of color complex (40).
Nitroso compounds and nitrones are the most common spin traps, both leading to nitroxyl type spin-adducts such as ct-phenyl-terfbutylnitrone (PBN)-adducts (Figure 5) (62). 9 ) = K + Ph R- *~ CMe3 R \ ' / \ CMe PBN MeaC — N = 0 + ρ. ^ R — Ν \ IV/IMD C M e 3 MNP Figure 5. Formation of nitroxyl radical spin adducts ESR spectroscopy is of great value for the study of the early stages of lipid oxidation and prediction of oxidative stability of fats and oils as well as evaluation of antioxidant activity.
