“…The use of polar co‐solvent such as ethanol may enhance the solvating power of CO 2 and thus improve the extraction of polar compounds in oil seeds . In fact, the co‐solvent can increase the mass transfer by cleaving bonds between plant matrices and solute . Moreover, the extractivity of polar compounds may be improved by a better penetration of Sc‐CO 2 into the matrix, due to swelling of the sample matrix with a co‐solvent …”

Introduction The consumption of health‐promoting products such as oil seeds may improve human health and prevent certain diseases. Carvi seeds have the potential to produce oil with nutritional and functional properties rich in active compounds. Objective To extract bioactive lipids from Carum carvi seeds using green methodologies. Material and methods Supercritical‐carbon dioxide (Sc‐CO2) and ethanol as co‐solvent and bio‐based solvent 2‐methyltetrahydrofuran (MeTHF) were used to extract the oil from Carum carvi. The yield, the chemical composition, as well as antioxidant and anti‐inflammatory activities of green extracted oils were investigated and compared to those obtained with conventional methods (hexane and Folch system). Results MeTHF extraction gave higher oil yield than that obtained by hexane. Fatty acids composition of the two obtained green extracted oils was similar to conventional extracted ones where petroselinic (39–43%), linoleic (29–31%) and oleic (19–21%) acids were the major compounds. Furthermore, MeTHF and Sc‐CO2 green extracted oils were enriched of bioactive compounds including sterols (5.4 and 7.3 mg/g oil) and total polyphenols (9.3 and 7.6 mg GAE/g oil) which were correlated to enhanced antiradical capacity. Moreover, the green extracted oils exhibited high anti‐inflammatory capacity inhibiting nitric oxide (NO) release in lipopolysaccharide (LPS)‐induced RAW 264.7 macrophages with IC50 values of 28 and 24 μg/mL. Conclusion Green solvents are a good alternative to petroleum solvents to recover oil from carvi seeds with high amount of nutritionally important fatty acids, along with significant antioxidant and anti‐inflammatory potential.

“…The difference in oil yield between the processes conducted by 1 and 5 h with solvent enriched by 10% of acetone was only 1.5-fold. This significant improvement in extraction rate was caused by easier release of solutes from plant matrices [11]. In this case, the mass transfer resistance is decreased [25].…”

“…This effect comes from two main sources. Firstly, a modifier can increase the mass transfer by cleaving bonds between plant matrix and solute [11]. The second mechanism of improving the extractivity of polar compounds consists of better penetration of SC-CO 2 into the matrix, due to swelling of the sample matrix with a co-solvent.…”

This study was conducted to show impact of supercritical fluid extraction using pure SC-CO2 or SC-CO2 enriched by 2, 6, and 10% of acetone, simultaneously varied by the extraction time (1 vs. 5 h), on the quality of chia seed oils. Obtained oils were relatively similar in the fatty acid composition, but they differed in total content of phytochemicals (from 4956 to 6391 mg/kg of oil). Among them, three oils were the most different: oil extracted 1 h with pure SC-CO2 (the most abundant in squalene, sterols, and tocopherols), oil extracted 5 h with pure SC-CO2 (the poorest in squalene, polyphenols, and carotenoids, with medium level of sterols and tocopherols) and oil extracted 1 h with SC-CO2 enriched by 10% acetone (the most abundant in polyphenols and carotenoids). Such unique chia oils can be valuable for special market needs, such as cosmetics, pharmaceuticals, functional food or diet supplement production.

“…Guarana is a plant native to the Amazon basin, which is largely used by beverage industries [174]. Guarana seeds contain the highest percentage (2%-8%) of caffeine, compared to any other plant, a high concentration of polyphenols (particularly proanthocyanidins) and small quantities of other stimulant purine alkaloids, such as theobromine and theophylline [174,175]. Two human RCTs reported increased energy expenditure [176] and short-term weight and fat loss [177] after Guarana extract administration.…”

The mass media has increasingly frequently suggested to the general population that specific foods or nutritional schemes are able to affect both human metabolism and energy expenditure, thus facilitating weight loss. This critical review is aimed at assessing available evidence on the roles of nutrients, food and dietary regimens in energy intake and energy expenditure. We queried the National Library of Medicine, the Cochrane Library, Excerpta Medica dataBASEand the Cumulative Index to Nursing and Allied Health Literature database, and a search strategy was performed by using database-specific subject headings and keywords. We found that available scientific evidence on these topics is scarce, and that the limited number of available studies often have poor methodological quality. Only a few foods show beneficial effects on metabolism and energy expenditure, as the human energy balance is complex and multifactorial. Finally, microbiota may interfere with the intake, use and expenditure of energy in the human body. Conclusive evidence is still lacking, and, at present, it is not possible to identify a food or a diet with a significant impact on human energy expenditure.
