Antioxidant - an overview | ScienceDirect Topics

Antioxidants used in food products, either natural or synthetic, can interact among themselves and result in synergistic, additive, and antagonistic interactions. Naturally occurring antioxidants, including antioxidant vitamins (e.g., vitamin C and vitamin E) and phytochemical antioxidants (e.g., polyphenols and carotenoids), when combined, can result in synergistic interactions, thus favor application in food systems.

Antioxidant Activity - an overview | ScienceDirect Topics

Antioxidant activity is defined “as an limitation of the oxidation of proteins, lipids, DNA or other molecules that occurs by blocking the propagation stage in oxidative chain reactions” and primary antioxidants directly scavenge free radicals, while secondary antioxidants indirectly prevent the formation of free radicals through Fenton’s reaction (Huang et al., 2005).

Antioxidant Capacity - an overview | ScienceDirect Topics

The antioxidant capacity of both white and red grapes and wines can differ and depends mostly on the cultivar, ripening stage, and wine-making techniques used. Wine-making practices such as skin contact, oxidation control, using more press juice, and enzyme additions may all influence the phenolic and thus antioxidant capacity of a wine.

Secondary Antioxidant - an overview | ScienceDirect Topics

4.2.1.1.2 Secondary Antioxidants. Secondary antioxidants, frequently referred to as hydroperoxide decomposers, act to convert hydroperoxides into nonradical, nonreactive, and thermally stable products. They are often used in combination with primary antioxidants to yield synergistic stabilization effects.

Antioxidants - an overview | ScienceDirect Topics

Antioxidant synergism is the cooperative effect of antioxidants, or an antioxidant with other compounds, to produce better antioxidant activity than the sum of activities of the individual antioxidants when used by themselves. For example, two or more phenolic antioxidants can give synergistic effects due to differences in steric hindrance.
