“…Table 5 represents a consolidated summary of studies using supercritical fluid-assisted techniques for the extraction of bioactive compounds from millets. Pang et al [ 24 ] optimized the protocols for supercritical CO 2 extraction of oils from FMB while varying pressure (25, 30, 35 MPa), temperature (40, 45, 50 °C), and time (1.5, 2, 2.5 h). Higher sterols were observed compared to conventional solvent extract (CSE).…”

“…Currently, there exists a substantial literature addressing innovative extraction methods for extracting bioactive compounds from millets and their by-products. For example, recently the novel and green-assisted extraction techniques including DES assisted technique for phenolic [ 20 ] and flavonoid compounds in sorghum [ 21 ], foxtail millet [ 20 , 22 ], Supercritical fluid extraction of phenolic compounds in Foxtail millet [ 23 , 24 ] and sorghum [ [25] , [26] , [27] , [28] ], US assisted technique for phenolic and flavonoid compounds in sorghum [ [29] , [30] , [31] , [32] ] and proso millet [ 33 ], Microwave-assisted technique for 3-DXA (3-deoxyanthocyanidins) flavonoid [ 34 ]and phenolic compounds in sorghum [ [34] , [35] , [36] , [37] ] and kodo millet [ 38 ], enzyme assisted technique for polyphenol and flavonoid compounds in pearl millet [ 39 , 40 ], finger [ 39 , 41 , 42 ], sorghum [ 39 , 43 ], foxtail [ 44 ]and proso millet [ 45 ] and accelerated assisted technique for phenols compounds in sorghum millet [ 46 ], have been employed for the extraction of millet bioactive components. However, after an extensive review of the literature, and to the author's best knowledge, no comprehensive review articles have been identified that offer an in-depth analysis of novel extraction techniques and their potential applications in the context of millet grains.…”

“…Although screw press extraction provides the advantages of low operational costs and produces uncontaminated oil, the extraction efficiency is quite low (< 70% oil extraction). Thus, the supercritical carbon dioxide extraction technology has been studied extensively as an alternative to conventional methods of oil extraction since it is nontoxic, nonflammable and easily separated from the extract (Pang et al, 2015). SC extraction has been widely applied to extract oil from plant seeds, such as canola seed (Pederssetti et al, 2011), kenaf seed (Abd Ghafar et al, 2013), Phaleria macrocarpa seed (Azmir et al, 2014) and okra seed (Dong et al, 2014).…”

SUMMARY: Peony seed oils (PSOs) were prepared using supercritical CO 2 (SC) and compared with soxhlet extraction (SE) and mechanical screw press extraction (SPE) methods. The fatty acid compositions of the oils were determined, and the physicochemical properties of the oils, including free radical-scavenging activity, α-amylase and α-glucosidase inhibition, thermal and rheological properties were evaluated. The unsaturated fatty acids in the SE oils were higher than SC and SPE oils due to the higher percentage of olefinic, allylic methylene and allylic methine protons in the SE oils. The SPE oils also displayed the highest DPPH and ABTS + radical scavenging activity at the tested concentrations. However, the SE oils showed stronger inhibitory effects on α-amylase and α-glucosidase enzymes under in vitro conditions when compared with the other oil samples. The three oils had similar melting and crystalline point due to similar contents of fatty acids (FAs). The SC oils had a lower E a than the others. KEYWORDS:Anti-α-amylase activity; Anti-α-glucosidase activity; Peony seed oil; Radical scavenging activity; Rheological properties RESUMEN: Efectos de la tecnología de procesos sobre las propiedades fisicoquímicas del aceite de peonía. Se prepararon aceites de semillas de peonia (PSOs) utilizando CO 2 supercrítico (SC) y se compararon con los métodos de extracción en soxhlet (SE) y de extracción mecánica de tornillos (SPE). Se determinaron las composiciones en ácidos grasos y se evaluaron las propiedades fisicoquímicas de los aceites incluyendo la actividad de eliminación de radicales libres, la inhibición de α-amilasa y α-glucosidasa, las propiedades térmicas y reológicas. Los ácidos grasos insaturados en los aceites SE fueron más altos que los aceites SC y SPE debido al mayor porcentaje de protones olefínicos, metileno alílico y metino alílico en los aceites SE. Los aceites SPE también mostraron una actividad de eliminación de radicales DPPH y ABTS+ más alta a las concentraciones ensayadas. Sin embargo, los aceites SE mostraron efectos inhibidores más fuertes sobre las enzimas α-amilasa y α-glucosidasa bajo condiciones in vitro cuando se compararon con las otras muestras de aceite. Los aceites tenían puntos de fusión y cristalinos similares debido a un contenido similar de ácidos grasos (FAs). Los aceites SC tenían un E a más bajo que los demás.

Millets are recognized as nutritional grains that have been important for preventing the malnutrition and significantly enhancing the human health. Foxtail millet (Setaria italica) is a C4, self pollinating millet species belonging to family Poaceae; acknowledged as Italian millet, Chinese millet or German millet. Being the oldest crops to be cultivated and produced, it is also utilized as a bird feed in African regions of the world. As far as the nutritional content is concerned, it has substantial amounts of carbohydrates (60–65 g), protein (12.3 g), fiber (6 g), minerals (Phosphorous, calcium, iron, zinc, magnesium, sodium), and phytochemicals (Phenols, Ferulic, chlorogenic acids, and p‐coumaric, flavonoids, carotenoids, tocopherol, and tocotrienol). Additionally foxtail millet is reported to have anti inflammatory, antioxidant, anticancerous, antihypolipidemic antihyperglycemic properties that may serve well with respect to pharmacological relevance. Apart from the medicinal prospect, its food utilization for making bakery, weaning, fermented as well as extruded goods are studied in the literature. Thus it can be mentioned that foxtail millet has a promising position in strengthening dietary quality and food security of world, thereby functioning as an emissary crop to replenish other economically valuable crops against environmental constraints even while supplying food for people and livestock via biotechnological techniques.
