(PDF) Optimization of Oil Extraction from Nigella sativa Seeds
In the current investigation the crude oil of Nigella sativa was extracted from seeds using hydraulic and screw pressing techniques. Different parameters were
Optimization of Oil Extraction from Nigella sativa Seeds by Pressing
Experimental design: Response surface methodology was used to optimize the oil extraction from Nigella sativa seeds by hydraulic press. The effects of independent variables, temperature (25-60 C), pressure (50-120 bars) and thickness cake (1.30-4.04 cm) on oil extraction were studied using the Box-Behnken design.
Extraction optimization for the antioxidants from Nigella sativa
Although many studies have explored the bioactive compound content of Nigella sativa (black seed BS) essential oil, data on the phenolic compound content
Optimization of Oil Extraction from Nigella sativa Seeds by Pressing
The oil of Nigella sativa seeds was extracted using hydraulic press. The pressure, temperature and thickness of cake have been optimized, using the Response Surface Methodology to...
Optimization of Oil Extraction from Nigella sativa
Sample preparation for oil extraction by hydraulic press: Oil extraction is carried out from Nigella sativa seeds using hydraulic press described by Acheheb et al. (2012) . The ground sample, having a particle size less than 1 mm, is compressed, during 60 min, at various pressures (50, 90
Optimization of yield and thymoquinone content of screw press-extracted
Because there have been no previous reports on the use of screw presses for black cumin (Nigella sativa L.) seed oil extraction, the present study examined the effects of feed rate, temperature, and moisture content on the yield and thymoquinone content of mechanically extracted cold-pressed black cumin seed oil. The extraction parameters were

Extraction optimization for the antioxidants from Nigella sativa seeds
Nigella sativa dried seeds were purchased from a local distributor. They were collected in the same year as the study was performed. The seeds were ground in an electric mill, and then a 2 g portion of seeds was covered with 30 ml of extraction solvent and shaken in a water bath in controlled temperature and time conditions.

Optimum Extraction Technology for the Seed Oil of Nigella sativa L.
Flow chart of N. sativa seed oil extraction. The oil yield can be calculated by using the following formula: In addition, two steps were conducted for refining the oil extract technology. In the first step, three comparatively ideal levels of the four factors were obtained by a series of single-factor tests.
