The antioxidant activities of coconut oil extracted under hot and cold conditions were compared. The
coconut oil extracted under hot conditions (HECO) contained more phenolic substances than the coconut
oil extracted under cold conditions (CECO). The antioxidant potential of HECO was higher than that of
CECO as demonstrated by DPPH assay, deoxyribose assay and in vivo assay of serum antioxidant capacity.
It is the common belief that virgin coconut oil extracted under cold conditions preserves several thermally
unstable antioxidants and, as a result, better beneficial qualities can be expected for virgin coconut
oil. However, high temperatures used in the hot extraction of coconut oil favour the incorporation of
more thermally stable phenolic antioxidants into coconut oil. Therefore, the consumption of HECO
may result in the better improvement of antioxidant related health benefits compared with the consumption
of CECO.
