Abstract
The essential oil content in cumin samples from Serbian market ranged between 2.0 and 4.0%, with 22 identified compounds, among which the most abundant were cumin aldehyde, β-pinene, γ-terpinene, γ-terpinene-7-al and p-cymene. Postdistillation cumin seeds waste material that remained after the essential oil extraction contains total polyphenols of between 30.1 and 47.5 mg GAE/g dry extract, as estimated by the Folin-Ciocalteu method. Hydroxybenzoic and hydroxycinnamic acids, as well as glycosides of flavonones and flavonoles, are the dominant polyphenols. However, according to DPPH method, the antioxidative potential of cumin postdistillation seeds waste was poor and it ranged between 0.02 and 0.04 mM TE/g. Further research will be focused on agro-food implementation of postdistillation waste material of cumin and other plants which are used for the essential oil production.
