However, they can affect the stability of oils during storage in home conditions, during which they exposed to light, kept open causing contact with the air, or kept at an ambient temperature.
The DPPH assay shown to be a good predictor of the oxidative stability of oils as determined using the Rancimat test and other thermal oxidations of oil.
These stability tests require elevated temperatures of oxidation (even 100 °C and higher) and exogenous oxidation promoters, which are not relevant to the normal storage conditions of cold-pressed oils
Therefore, the objective of this research was to assess the initial antioxidant activity and oxidative stability of selected cold pressed oils throughout their shelf life as well.
As to characterize the relationship between the antioxidant activity of nonfractionated and fractionated oils and the parameters of oil oxidation measured.
