Abstract

A conventional Korean meal typically includes various roasted, steamed, stir-fried, and braised foods. For this study, we investigated the contents of water soluble vitamins, $B_1$ (thiamin), $B_2$ (riboflavin) and $B_3$ (niacin) in various roasted, steamed, stir-fried, and braised foods. Method validation for analytical data in this study showed a high linearity ($r^2$>0.999), and the limit of detection and quantification were 0.001-0.067 and $0.002-0.203{\mu}g/mL$, respectively. For accuracy and precision, analytical values using standard reference materials were in the certified ranges. Roasted foods contained 0.039-1.057 mg/100 g of thiamin, 0.058-0.686 mg/100 g of riboflavin and 0.021-21.772 mg/100 g of niacin. Steamed foods contained 0.049-1.066 mg/100 g of thiamin, 0.025-0.548 mg/100 g of riboflavin and 0.134-21.509 mg/100 g of niacin. Stir-fried foods contained 0.114-0.388 mg/100 g of thiamin, 0.014-1.258 mg/100 g of riboflavin and 0.015-2.319 mg/100 g of niacin. Braised foods contained 0.112-1.656 mg/100 g of thiamin, 0.024-0.298 mg/100 g of riboflavin and 0.322-2.157 mg/100 g of niacin. The data on water-soluble vitamins in this study can be used for a nutritional database of conventional Korean meals.

본 연구는 국내 식생활의 기본적인 구성식단으로 알려진 구이, 찜, 볶음, 조림에 존재하는 다양한 영양성분 중 수용성 비타민인 $B_1$ (thiamin), $B_2$ (riboflavin), 그리고 $B_3$ (niacin)의 함량을 확인하였다. 실험분석 타당성 검증을 통해서 높은 직선성($r^2$>0.997)을 확인하였고, 검출한계의 경우 $0.001-0.067{\mu}g/mL$ 그리고 정량한계의 경우 $0.002-0.203{\mu}g/mL$를 확인하였다. 또한 실험값에 대한 정밀도와 반복성에 대한 검증을 위해서 standard reference materials를 통해 실험값과 표준값과의 오차가 신뢰도 이내에 존재한다는 결과를 확인하였다. 본 연구에서 제시된 구이식품의 경우 thiamin은 0.039-1.057 mg/100 g의 범위에 존재하였고, riboflavin은 0.058-0.686 mg/100 g의 범위에 존재했으며, niacin의 경우 0.021-21.772 mg/100 g 의 범위로 나타났다. 찜 종류의 경우 thiamin은 0.049-1.066 mg/100 g의 범위에 존재하였고, riboflavin은 0.025-0.548 mg/100 g의 범위에 존재했으며, niacin의 경우 0.134-21.509 mg/100 g의 범위로 나타났다. 볶음의 경우 thiamin은 0.114-0.388 mg/100 g의 범위에 존재하였고, riboflavin은 0.014-1.258 mg/100 g의 범위에 존재했으며, niacin의 경우 0.015-2.319 mg/100 g의 범위로 나타났다. 조림의 경우 thiamin은 0.112-1.656 mg/100 g의 범위에 존재하였고, riboflavin은 0.024-0.298 mg/100 g의 범위에 존재했으며, niacin의 경우 0.322-2.157 mg/100 g의 범위로 나타났다. 본 연구에서 제시된 구이, 찜, 볶음, 그리고 조림 식품에 대한 수용성 비타민 함량에 대한 영양성분 데이터베이스 구축 연구가 국민 식생활의 중요한 기초자료로 이용될 것으로 확신한다.
