“…This is due to greater solvent density (solvating power) of CO 2 at higher pressure that improves mass transfer and enhances solubility of solute in the solvent. This result was in agreement with previous works reported on the SC-CO 2 extraction of several seed oils [20][21][22][23]. At pressures above 20 MPa, the solubility of neem oil increases with temperature increase, denoting the crossover pressure region (Fig.…”

“…This effect may be stronger with smaller particle sizes. Hence, extraction yield increases with the decrease of the particle size, as noted in the literature (Yin et al, 2005;Salgin et al, 2006;Ozkal et al, 2005;Louli et al, 2004). According to previous investigations (Glisic et al, 2007;Sandra et al, 2007;Zizovic et al, 2007), we can also get a conclusion: Particle size has no influence on the extraction rate in two outermost cases: Fine milled material and coarsely ground plant material.…”

“…Use of SFE technology that offers suitable extraction and fractionation appears to be promising for the food and pharmaceutical industries. There are many literatures about the natural materials extraction with SFE such as vetiver root , sunflower (Salgin et al, 2006;Fiori, 2009), banana peel (Comim et al, 2010), jojoba seed (Salgin, 2007), grape seed (Fiori, 2007;Passos et al, 2009;Yilmaz et al, 2010) and sesame seed (Corso et al, 2010).…”

Supercritical fluid extraction (SFE) is one of the most commonly used extraction techniques in the course of analysis or preparation. It is environmentally friendly and has some advantages over other conventional extraction methods. This review covers the recent developments of SFE in the extraction of essential oils from the plant materials during the period 2005 to 2011, in particular some factors influencing SFE extraction yield, its characteristics and applications.

“…The results are shown in Figure 1 where it can be observed that the higher the temperature the higher the extraction rate, which may indicate that, at this pressure, the increase of oil vapor-pressure with temperature is more important than the decrease in SC-CO 2 density. As it is well established in literature [16], an increase of seed oil solubility with extraction temperature can be significant when the process is performed at pressures higher than 40 MPa, pressure at which a crossover behavior is usually observed in vegetables oils [16].…”

The supercritical fluid extraction of corn germ oil has been studied in this work.Extractions were carried out at different pressure, temperature and flow rate to analyse the influence of these variables on the extraction kinetics and the oil quality obtained.Extraction curves are initially linear with a slope close to the oil solubility value in supercritical CO 2 . Based on these results a mathematical model was successfully applied to describe the extraction curves. Characterization of supercritical crude corn oil was performed by determining some physical parameters such as refraction index, density and color. Additionally, the fatty acid composition, neutral lipids, the content of tocopherols, acid index, peroxide value, antioxidant capacity and the oxidative stability * Corresponding author 3 were determined in the corn oil extracted. Fatty acid composition was compared with that for crude germ oil and no significant differences between the oils extracted by both methods were found. Oxidative stability test using the Rancimat showed that supercritical CO 2 extracted corn oil is less protected against oxidation than n-hexane extracted oils.
