Experimental and modelling of supercritical oil extraction from rapeseeds and sunflower seeds

Supercritical extraction of sunflower oil: A central composite design for extraction variables

“…The total sunflower oil extracted with n-hexane is comparable with the extracted oil reported by Hartman, Antoniassi, and Freitas (1999) who obtained 54.80% total oil with sunflower seed obtained from Brazil. However, this value is much higher as compared to the 45.1%, 47.83-53.41% and 52% yield reported by Boutin et al (2011), Hartman et al (1999 and Salgin et al (2006) respectively. This type of variation in the total oil content may be due to geographical conditions such as seasonal temperature, nutrients and water availability, soil properties (Kemper, 2005).…”

Effect of supercritical CO2 extraction process parameters on oil yield and pigment content from by‐product hemp cake

“…The extraction pressure also had a significant effect on the amount of extracted residual oil from the pressed cake. As expected, the rate of SFE of hemp cake oil increased with the increase in extraction pressure, as well as the seed oil solubility (Özkal et al ., ; Martínez et al ., ; Döker et al ., ; Boutin et al ., ; Jokić et al ., ). Depending on the applied pressure the extraction yield was in the range from 10.11 to 14.97% during same time of extraction.…”

Supercritical extraction of oil seed rape: Energetic evaluation of process scale

“…Their yields varied from 0.3% to 89.8% compared to an organic solvent extraction, concluding that the main parameter that influenced the extraction was the pressure, while temperature had a small influence (beyond the retrosolubility point). Boutin et al [8] also developed the modelling of the extraction in different conditions (30-34 MPa, 45-70 • C, 5-25 kg/h of CO 2 ).…”

“…The supercritical fluid extraction of oil seed rape is potentially a large scale application of this technology that has been thoroughly studied [1][2][3][4][5][6] and modelled [7,8], but still has not been industrially applied.…”
