AbstractThe purpose of this study is to evaluate the chemical composition, antioxidant and anti-bacterial activity of cumin essential oils (CEOs) extracted by different techniques, including supercritical carbon dioxide extraction (SCE), subcritical butane extraction (SBE) and traditional solvent extraction (SE). Our results indicated that CEOs are a valuable source of bioactive compounds, including cumin aldehyde, γ-terpinene and β-pinene. The most abundant components found in CEOs obtained by SCE and SBE were similar, while the abundant components in SE, β-Cumic aldehyde (19.31%) and α-phellandrene (9.49%), were distinctive. CEOs obtained by SCE exhibited higher antioxidant activity, followed by those extracted by SE and SBE. Moreover, the anti-microbial properties of CEOs obtained by SCE and SBE were higher than that of CEOs collected by SE. In conclusion, CEOs exhibit strong antioxidant and anti-microbial properties, which suggests a potential role of CEOs in preventing diseases associated with aging and oxidative stress, and our results highlight the potential usage of CEOs in the food industry.
