Abstract

This study investigated the quality characteristics (chemical composition, amino acid content, lipid content, and rutin content) of common and tartary buckwheats cultivated from Korea and China. The moisture, crude protein, crude fat, crude ash, and carbohydrate contents of various common and tartary buckwheats were 8.78~13.37%, 11.00~12.11%, 2.87~3.18%, 1.80~2.58%, and 70.2~73.8%, respectively. The major amino acids in Korean and Chinese buckwheats were aspartic acid (1,105.1~1,403.5 mg/100 g), glutamine (2,250.9~2,996.1 mg/100 g), and arginine (932.5~1,388.6 mg/100 g). The major minerals were K (423.7~569.4 mg/100 g), Mg (181.8~255.9 mg/100 g), and P (328.6~555.0 mg/100 g). Palmitic acid (14.2~16.1%) was the major saturated fatty acid, and oleic (37.0~40.8%) and linoleic (31.7~38.6%) acids were the major unsaturated fatty acids. Tartary buckwheats (261.0~265.0 mg/g) had significantly higher rutin contents than that of common buckwheats (4.39~5.68 mg/g). These results suggested that common and tartary buckwheats cultivated in Korea and China contain naturally occurringnutrients in an abundance.

본 연구는 국내산 및 중국산 단메밀과 쓴메밀의 일반성분, 아미노산 조성, 지방산 조성과 루틴 함량을 분석하였다. 다양한 메밀의 수분, 조단백질, 조지방, 조회분, 탄수화물의 함량은 각각 8.78~13.37, 11.00~12.11, 2.87~3.18, 1.80~2.58, 70.2~73.8%로 분석되었다. 국내산 및 중국산 메밀의 주요 아미노산은 aspartic acid(1,105.1~1,403.5mg%), glutamine (2,250.9~2,996.1 mg%), arginine(932.5~1,388.6 mg%)로 분석되었으며, K(423.7~569.4 mg%), Mg(181.8~255.9 mg%), P(328.6~555.0 mg%)가 주요 미네랄로 분석되었다. 한편, 지방산 조성은 포화지방산인 palmitic acid(14.2~16.1%)와 불포화 지방산인 oleic acid(37.0~40.8%), linoleic acid(31.7~38.6%)가 주요 지방산으로 분석되었다. 또한, 국내산 및 중국산 메밀의 주요 phenolic compound는 루틴으로 분석 되었으며, 쓴메밀(261.0~265.0 mg/g)이 단메밀(4.39~5.68 mg/g)보다 높은 함량을 보였다. 본 연구를 종합하면, 국내산 단메밀은 중국산 단메밀과 비교하여 영양성분은 크게 차이를 보이지 않았으나, 메밀의 주요 활성성분인 루틴은 약간 높게 함유되어 있었다. 또한 국내산 쓴메밀은 중국산 쓴메밀에 비하여 Ca, Fe 함량이 높았으며, 루틴 역시 약간 높은 함유량을 보였다. 따라서, 메밀에서 주요 활성성분으로 제시되고 있는 루틴의 함량이 중국산 메밀보다 국내산 메밀에 높게 함유되어 있기 때문에 국내산 메밀에서 더 높은 생리활성이 나타날 것으로 기대된다.
