Abstract

Antioxidants are components which prevent autooxidation of oils and fats by giving their hydrogen to free
radicals formed in the initiation and propagation stages of
autoxidation by following reactions (Bose et al., 2021).
The antioxidant activity of the oils arises of phenolic
compounds, vitamin-E-active compounds, phytosterols
and other bioactive compounds. The published results for
the antioxidant activity of edible oils varies in huge range
due to the different amount of bioactive compounds as
well as different antioxidant assays (DPPH, TEAC and
FRAP assay) (Kostadinović Veličkovska et al., 2015).
Cold-pressed oils are known for their antioxidant and
other positive health effects. Among them, virgin coldpressed olive oil has the primate between the other
vegetable edible oils. Other oils, as well as sesame seed
oil, pumpkin seed oil, “sweet” and “bitter” apricot kernel
oils, and paprika seed oil, have also been recognized as
rich sources of tocopherols and tocotrienols, polyphenols,
and essential mono and polyunsaturated fatty acids
(Kostadinović Veličkovska et al., 2018). But the process
of extraction or modification of these oils could affect
their ability to capture the free radicals and even in theory it is very smooth and easy, in practice, antioxidant
capacity could be altered by many factors.
