Cholesterol content of fried-shredded pork extracted by supercritical carbon dioxide

Optimization of process parameters for supercritical fluid extraction of cholesterol from whole milk powder using ethanol as co‐solvent

“…20 Vedaraman et al 21 removed 52% cholesterol from cow brain using scCO 2 under extraction conditions of 50 ∘ C and 25 MPa. Lin et al 22 produced fried shredded pork of reduced cholesterol content (50.5%) utilizing SCFE at 34.45 MPa/50 ∘ C. Wehling et al 23 extracted as much as 87% cholesterol and other lipids from dehydrated beef powders and chunks at 55 ∘ C and a fluid density of 0.9 g cm −3 . Under the conditions of 31 MPa, 1875 L CO 2 and 37 ∘ C, it was possible to obtain a low-cholesterol shrimp with acceptable organoleptic properties.…”

Removal of Lipid and Cholesterol From Goat Placenta by Supercritical Carbon Dioxide Extraction

“…Previous studies on supercritical carbon dioxide (SC-CO 2 ) extraction of essential oils, seed oils and fruit oils (Xu et al 2008), removal of caffeine from coffee (King 2000) or green tea (Kim et al 2008), extraction and separation of chemotherapeutic agents (King 2000) and production of biological active protein powders (Debenedetti et al 1993;Yeo et al 1993) have demonstrated that SC-CO 2 technology offers a number of advantages over conventional methods, including non-solvent residues, low-to-moderate temperatures, exclusion of oxygen and minimal protein degradation (Brunner 2005). There are also several applications of SC-CO 2 to lower cholesterol level in animal products such as ground beef (Chao et al 1991;Wehling et al 1992), chicken (Froning et al 1994), pork (Lin et al 1999), cow brain (Vedaraman et al 2004(Vedaraman et al , 2005, shrimp (Higuera-Ciapara et al 2005), fish muscle (Hardardottir and Kinsella 1988), butter oil (Mohamed et al 1998) and egg yolk (Warren et al 1991;Froning et al 1998). The aforementioned studies showed that a large quantity of total lipid and cholesterol was preferentially removed from animal matrixes during SC-CO 2 extraction.…”

Influence of supercritical CO2 pressurization on the phase behavior of mixed cholesteryl esters

“…At this regard, benign supercritical CO 2 extraction seems promising as it possesses many desirable features for separating and purifying desired components from natural products and foods. Therefore, a number of recent studies have been contributed to the cholesterol reduction by using supercritical fluid extraction methodology from cattle brain (Vedaraman et al, 2004(Vedaraman et al, , 2008, cow brain (Vedaraman et al, 2005), shrimp (Higuera-Ciapara et al, 2005), pork (Lin et al, 1999), chicken meat (Froning et al, 1994), turtle fish egg (Shen et al, 2008), egg yolk (Bringe, 1997;Froning et al, 1998), butter oil (Mohamed et al, 1998(Mohamed et al, , 2000 and squid oil (Kang et al, 2005). These researches have indicated that supercritical fluid extraction technology holds promise for substantially reducing cholesterol contents and thus offers an alternative to current methods of developing low-cholesterol foods.…”
