대마[Cannabis sativa L.]는 오랫동안 섬유작물로 재배되었지만 종실의 기름 함량이 많고 불포 화지방산 비율이 높아 식용유 원료작물로 유망하다. 오랫동안 대마 종실유를 이용해온 유럽의 여러 나라에 서는 압출식으로 착유하는데, 이용 역사가 짧은 우리나라에서는 대마 종실유에 대한 정보 부족으로 소비자 기호도가 낮은 편이다. 본 연구는 압착식과 압출식으로 착유한 대마 종실유의 성분을 분석하여 소비자들에 게 올바른 정보를 제공하기 위해 수행하였다. 압출식 착유기로 착유하면 착유량이 압착식에 비해 많았다. 착유 부산물인 유박은 압출식에서는 으깨어져 얇고 납작하게 배출되지만, 압착식은 종실이 다소 납작해졌 으나 종실의 형상을 유지하였다. 압출식 착유 종실유는 압착식에 비해 Chlorophyll A, B 및 Carotenoid 함 량이 높아 명도(L)는 낮고 녹색과 황색은 진하였다. 지방산 조성에서 Palmitic acid, Stearic acid, Oleic aicid, γ-Linolenic acid 비율은 압출식 착유 종실유가 압착식에 비해 다소 높았으나, Linoleic acid와 α -Linolenic acid는 낮았다. 대마 종실유는 총 토코페롤 함량이 많고 그 중 γ-Tocopherol 함량이 많은 것 이 특징이었는데 압출식 착유 종실유가 압착식에 비해 다소 적었다.

Hemp [Cannabis sativa L.] has been cultivated as a fiber crop for long history, but it was a good oil crop because its seed contain plenty of lipid which is high ratio of unsaturated fatty acid. Hemp seed oil was extracted with a extruding method in many countries including Europe. The color of oil extracted with extruding method is dark green which could be difficult to attract consumer’s interest in Korea because of insufficient information about hemp seed oil. This study was conducted to know correct information about hemp seed oils which were extracted with pressuring and extruding methods. In extruding method, seeds were crushed during the extracting process and discharged oil cake in shape of thin ribbon, but maintained seed shape although the seed were slightly flatted in pressuring method. Oil yield were higher in the extruding method in comparison with pressuring method. The oil have lower degree of lightness but higher degree of greenness and yellowness in the extruding method in comparison with pressuring method because of higher content of chlorophyll A, B and carotenoid. In fatty acid composition, the ratio of palmitic acid, stearic acid, oleic acid and γ-linolenic acid were higher but linoleic acid and α-linolenic acid were lower in the extruding method in comparison with pressuring method. The content of total tocopherol and γ -tocopherol were lower in the extruding method in comparison with pressuring method.
