Supercritical Carbon Dioxide Extraction of Daidzein and Genistein from Soybean Products

Supercritical Carbon Dioxide and Subcritical Water: Complementary Agents in the Processing of Functional Foods

“…The third stage yielded a low mass recovery containing 76% triglycerides, 2% sterols and 2% ferulate-phytosterol esters. Other studies utilizing an SFE-SFC system purification approach are Chandra and Nair (1996) for the extraction of isoflavones from soya-based products and Montanari et al (1999) for the isolation from deoiled soy meal. In contrast to using an elution-type batch SFC system, studies have been conducted on simulating moving bed-SFC (or SMB-SFC) systems.…”

Extraction of soybean isoflavones from soybean meal with aqueous methanol modified supercritical carbon dioxide

“…by causing breakthrough problems in a solid-phase trap (Berglof et al, 1998;Bjorklund et al, 1998). Chandra and Nair (1996) (20% v/v) at flow rates of 950-1000 ml/min during a 60-min extraction. Rostagno et al (2002) carried out their experiments at 40-70°C, 20-36 MPa, CO 2 flow rate of 1 ml/min for 90 min, using 70% methanol as modifier.…”

Continuous hot pressurized fluids extraction of isoflavones and soyasaponins from defatted soybean flakes

“…They have claimed a concept of extracting organic compounds from plant materials by using hot pressurized fluid. Chandra and Nair (1996) have examined supercritical carbon dioxide (CO 2 ) extractions of isoflavones from soybean products, including daidzein and genistein. Rostagno et al (2002) reported that 40% of isoflavones (daidzein and genistein) have been extracted by using supercritical CO 2 added with a co-solvent, but is still lower than that of Soxhlet 80% methanol/water extraction.…”
