국내 육성 잡곡에 함유된 Thiamine, Riboflavin 및 Niacin 함량

국문 초록 (Abstract)

잡곡은 영양학적 이점으로 인해 많은 연구가 수행되고 있으나, 국내에서 육성된 잡곡류의 수용성 비타민 함량 정보는 부족한 실정이다. 따라서 본 연구는 국내 육성 잡곡류에 함유된 수용성 비타민 thiamine, riboflavin 및 niacin 함량을 HPLC를 이용하여 정량 분석하였으며, 주성분분석을 통해 분류 특성을 검토하였다. Thiamine 및 riboflavin이 가장 많이 함유된 잡곡은 기장이었으며, niacin이 가장 많이 함유된 잡곡은 보리였다. 반면 옥수수는 thiamine 및 niacin 함량이 가장 낮은 잡곡이었다. 본 결과를 주성분분석으로 검토한 결과, 잡곡류의 종류에 따라 서로 다른 그룹으로 구분이 되는 것을 확인하였다. 다만, 옥수수는 품종에 따른 riboflavin 및 niacin 함량 변이가 큰 잡곡이었으며, 기장과 그룹이 overlap 되는 양상임을 확인하였다. 본 연구결과는 향후 국가표준식품성분표 제10개정판 출간에 필요한 데이터베이스로 활용될 것이다.

다국어 초록 (Multilingual Abstract)

Although many studies have been conducted worldwide on various nutritional benefits of minor cereals, there is insufficient information on the content of water-soluble vitamins in Korean minor cereal (barley, foxtail millet, maize, oat, proso millet, and sorghum) cultivars. This study therefore quantitatively analyzed the content of water-soluble vitamins, like thiamine, riboflavin, and niacin contained in Korean minor cereals using an high-performance liquid chromatography (HPLC), and the classification characteristics were reviewed through principal component analysis (PCA). Foxtail millet used in this study had the highest thiamine and riboflavin content, and barley contained the most niacin among minor cereals. Among the minor cereals reviewed in this study, maize had the lowest thiamine and niacin. Thereafter, as a result of a PCA review, it was possible to confirm the classification of thiamine, riboflavin, and niacin and to separate them into different groups according to the kinds of minor cereals. However, maize was a minor cereal with a large variation in riboflavin and niacin content depending on the cultivar, and its classification overlapped with proso millet. The results of this study provide a database necessary for the publication of the 10th edition of the Korean Food Composition Table.
