영문 초록

Supercritical carbondioxide is very effective in removing oils from a variety of seed matrices, devoid of any appreciable amount of phospholipid content. However, the limited solubility of phosphalipids in supercritical carbondioxide leaves behind a potentially valuable by-product in spent seed matrix. Any phospholipid extraction process from the spent matrix must maintain the structure and the quality of phospholipids and must be compatible with the end use of the seed protein meal an animal feed or for human consumption. An initial supercritical carbondioxide extraction of soybean flakes was performed at 32 MPa and 80℃ to extract the oils, leaving the phospholipids in the deflatted soybean flakes, A second step was performed on the defatted soybean flake using Xeth=0.10, Varying the pressure from 175 MPa to 70.6 MPa and temperature from 60℃ to 80℃. For all supercritical carbon dioxide/ethanol mixture extractions, a fraction rich in phospholipids was obtained. The fractions extracted from defatted soybean flakes were dried and them redissolved in chloroform before HPLC-ELSD analysis. Quantitative and qualitative analysis of phospholipids on soybean seeds, defatted soybean flake, and different extracted phospholipid fractions was carried out, to ascertain the effect of extraction pressure and temperature.
