The Effects of Supercritical Carbon Dioxide on the Extraction of Perilla Oil

초임계 이산화탄소가 들기름의 추출에 미치는 영향

  • Published : 2006.12.29

Abstract

This study was performed on the effects of extraction temperature, pressure, time on apparent solubility and extraction yield of perilla oil and tocopherol, and color and fatty acid composition of the residue in supercritical carbon dioxide $(SC-CO_2)$ extraction. Apparent solubility of perilla oil and tocopherol increased with the increase of $CO_2$ density and was found to strongly depend on extraction pressure rather than extraction temperature. The extract yield of tocopherol in $SC-CO_2$ extraction increased with an increase of temperature and decreased with an increase of pressure and extraction time. The perilla oil apparent solubility of dried perilla powder for $60\sim180$ min at $40^{\circ}C/276$ bar increased with an extraction time, on the other hands, tocopherol apparent solubility decreased. As the increase of $CO_2$ density, less redness and yellowness increased. Fatty acid composition of perilla oil showed that perilla oil extracted by $SC-CO_2$ had better unsaturated fatty acid and decreased in saturated fatty acid. $SC-CO_2$ extraction offers a safe natural method for gaining perilla oil from dried perilla seeds powder.
