“…In the most studies on the SC‐CO 2 extraction of fennel oil, 26,27 they focused on the total extraction yield of the extract (global yield); however, our object is to determine the oil yield and content of trans‐ anethole which is the main chemical component of the fennel essential oil. The SC‐CO 2 method has advantages over traditional extraction methods such as short extraction time, low extraction temperature, environmental friendly, and the possibility of optimizing the operational parameters of the extraction.…”

Fennel (seeds of Foeniculum vulgare Mill.) is the widely used aromatic and medicinal plant throughout the world. In this research, supercritical carbon dioxide (SC‐CO2) extraction was carried out to extract the aromatic extract from F vulgare seeds under various operating conditions, and aromatic extract samples were characterized for properties such as yield and trans‐anethole content. A three‐level Box‐Behnken design from response surface method was applied to optimize the extraction parameters such as pressure, temperature, and extraction time with an aim to obtain high yield and rich trans‐anethole content. The optimum extraction conditions were found to be 177 bar, 40°C and 68 min where the predicted oil yield and trans‐anethole contents were found to be 3.798% and 95 mg/g, respectively. Under the optimum conditions, the experimental oil yield was 3.85%, and the content of trans‐anethole was 94 mg/g. The results were very close to the values predicted by the model. At the same time, the chemical compositions of the oils from two different extraction methods, hydrodistillation and SC‐CO2, were compared. The chemical constituents of oils from two different extraction methods found to be the same, and they showed slight difference in terms of the quantity of the main chemicals. Antibacterial and antioxidant effects of the oils obtained by the two extraction methods were compared, and they showed similar effects.

“…In SFE, pressure and temperature play a key role, and their optimization is essential to determine the ideal operating parameters to obtain the best balance between yield and economic performance (Hatami, Johner, et al., 2020; Molino et al., 2020). The performance of SFE is highly dependent on the temperature, since with increasing temperature the solvent density decreases affecting the yield negatively, while on the other hand the solute vapor pressure increases influencing the yield positively.…”

The global trade of tropical fruits is expected to increase significantly in the coming years. In 2018, the production was approximately 100 million tones, an increase of 3.3% compared to the previous year. Nevertheless, according to the Food and Agricultural Organization, every year one‐third of the food produced in the world for human consumption is lost or wasted. More specifically, around 45% of the fruits, constituted mainly by peels, seeds, and pulps after juice extraction, are discarded mainly in the agricultural and processing steps. Therefore, decreasing and/or using these byproducts, which are often rich in bioactive components, have become an important focus for both the scientific community and the fruit processing industry. In this line, supercritical fluid extraction (SFE) technology is expected to play a significant role in the valorization of these byproducts. This review presents the concepts of a tropical fruit biorefinery using supercritical CO2 extraction and the potential applications of the isolated fractions. There is a specific focus on the extraction of bioactive compounds, that is, carotenoids and phenolics, but also oils and other valuable molecules. Moreover, the techno‐economic and environmental performance is assessed. Overall, the biorefinery of tropical fruits via SFE provides new opportunities for development of food and pharmaceutical products with improved economic and environmental performance.
