There are various products that can be obtained from ginger (Zingiber officinale Roscoe) rhizomes, such as
dried products, being difficult to choose the best option for antioxidant purposes. In this study, three different
dried forms of ginger rhizomes (freshly dried, dried and powder dried) were characterized in terms
of chemical composition including individual profiles in sugars, organic acids, fatty acids, tocopherols,
and antioxidants (phenolics and flavonoids). The in vitro antioxidant properties (free radicals scavenging
activity, reducing power and lipid peroxidation inhibition) of their methanolic extracts were also evaluated.
The results of this study indicate that the ginger form has significant influence in chemical and
antioxidant parameters of the plant; dried ginger (DG) proved to be the best choice. Overall, this study
could help the consumer in the selection of the most suitable option regarding antioxidant purposes.
