초록

1913년부터 2013년까지 국내에서 육성된 172품종에 대한 종실의 단백질, 지방 함량과 지방산 조성의 변이는 다음과 같다. 총 단백질 함량의 평균은 38.6%(31.6~45.3%), 지방함량의 평균은 18.4%(15.3~21.5%), 포화지방산 중 Palmitic acid의 함량은 평균11.11%(8.1~13.5%), Stearic acid의 함량은 평균 3.7%(1.9~5.4%), 불포화지방산인 Oleic acid의 함량은 평균 26.4%(13.1~41.8%), Linoleic acid의 함량은 평균 50.9% (37.2~63.0%), Linolenic acid의 함량은 평균 7.6%(5.7~9.8%), Linoleic(ω-6)/Linolenic(ω-3)acid의 비율은 평균 6.8(5.3~8.9)이여서, 포화지방산이 평균 14.8%(10.8~17.6%), 그리고 불포화 지방산 함량은 평균 84.9%(79.9~88.7%)이었다. 단백질 함량이 가장 높은 품종은 45.3%로 새단백콩이었으며, 지방함량이 가장 높은 품종은 21.5%를 함유한 늘찬콩이었다. 고 Oleic acid 함량인 동시에 저 Linoleic acid 함량인 검정콩1호는 양질의 지방산을 함유한 매우 유용한 품종이었다. 용도에 따른 단백질, 지방 지방산의 평균함량 중 단백질의 함량은 풋콩 및 올콩용 품종이 가장 높았고, 지방 함량은 장류용 품종이 가장 높았으며, 포화지방산은 장류용품종이 가장 낮았고, 불포화지방산의 함량은 풋콩 및 올콩용 품종이 가장 낮았다. ω-6/ω-3의 비율은 밥밑용 품종이 가장 낮았다. 종피색에 따라서는 단백질 함량은 녹색콩이 가장 높았으며 지방함량은 황색콩이 가장 높았다. 포화지방산은 황색콩과 검정콩이 가장 낮았으며, 불포화 지방산은 갈색콩이 ω-6/ω-3의 비율 또한 갈색콩이 가장 낮게 나타났다.

This study was carried out to investigate the variation of protein, oil and fatty acid contents of 172 Korean soybean varieties released from 1913 to 2013. The protein, oil and fatty acid contents were compared by utilization types and seed color. By each component, protein content was 38.6% (ranged from 31.6% to 45.3%), oil content was 18.4% (15.3% - 21.5%). The content of palmitic acid in saturated fatty acids (SFA) was 11.1% (8.1% - 13.5%), and stearic acid content was 3.7% (1.9% - 5.4%). The content of oleic acid in unsaturated fatty acids (USFA) was 26.4% (13.1% - 41.8%). Linoleic acid content was 50.9% (37.2% - 63.0%)%. Linolenic acid content was 7.6% (5.7% - 9.8%). Linoleic/Linolenic acid ratio content was 6.8% (5.3% - 8.9%). The highest protein content was 45.3% in Saedanback, highest oil content was 21.5% in Neulchan. High oleic acid contents and low linoleic acid contents of Gemjong1 is very high quality fatty acids. In comparison among the protein, oil and fatty acid average contents according to utilization types, protein was the highest in vegetable & early maturity group, and oil was the highest in sauce and paste group. SFA were lowest in soy sauce and paste group, and USFA were lowest in vegetable & early maturity group. The ratio of ω-6/ω-3 was the lowest in cooking with rice group. In comparison among the protein, oil and fatty acid average contents according to seed color, protein content was highest in green seeds, oil content was highest in yellow seeds. SFA were lowest in yellow and black seeds, and USFA were lowest in brown seeds. The ratio of ω-6/ω-3 was also the lowest in brown seeds.
