영어 초록
In order to optimize the supercritical fluid extraction (SFE) conditions of ginger oleoresin (GO), we conducted an evaluation of quality properties such as yield (%), color, volatile flavor compounds and gingerol components. The extraction yield gained by SFE increased as extraction pressure and temperature increased. The highest yield was 8.96 ± 0.68% at 500 bar 65℃ extraction condition. The total color difference (ΔE) values decreased at high pressure. In case of the 100 bar pressure conditions, ΔE-values increased as the temperature went up. The analysis of the 6-gingerol, 8-gingerol, 10-gingerol, 6-shogaol and curcumin contents decreased at high temperature conditions of identical pressure and increased at high pressure conditions. The volatile flavor compounds were detected in zingiberene,β-sesquiphellandre, β-phellandre, αγ-curcumene, 2,3-butandiol, β-bisabolene and so on. Also volatile component contents showed difference in each of extraction conditions.
