초록

본 연구는 식품성분표 개정을 위한 기초연구로서 농산식품인 조미료류 5개, 차류 2개, 채소류 2개, 곡류 3개, 견과류 및 종실류 6개, 유지류 2개, 과일류 20개에 함유되어 있는 기능성 영양성분 중 하나인 베타카로틴 함량을 분석하였다. 대표성과 신뢰성이 확보된 베타카로틴의 분석품질을 확보하기 위하여 참값을 알고 있는 표준인증물질인 slurried spinach(SRM 2385)의 베타카로틴 함량을 측정한 결과 RSD 1.73%였으며, 회수율은 102%로 아주 양호한 결과를 얻었다. 농산식품 분석 결과 채소류와 차류에서 비교적 높은 베타카로틴 함량이 검출되었다. 보리순가루 $17,293.95{\mu}g/100g$($2,882.33{\mu}gRE$), 보리순 생것 $2,755.15{\mu}g/100g$($459.19{\mu}gRE$), 녹차가루 $7,579.04{\mu}g/100g$($1,263.17{\mu}gRE$), 마른 녹차잎 $13,671.85{\mu}g/100g$($2,278.64{\mu}gRE$)으로 베타카로틴 함량이 비교적 높았다. 견과류 및 종실류의 베타카로틴 함량 분석 결과 검은 참깨 마른 것 $41.27{\mu}g/100g$($6.88{\mu}gRE$), 들깨 마른 것 $33.06{\mu}g/100g$($5.51{\mu}gRE$), 흰 참깨 마른 것 $25.36{\mu}g/100g$($4.23{\mu}gRE$) 순으로 베타카로틴 함량이 검출되었다. 유지류의 베타카로틴 함량 분석 결과 들기름 $58.56{\mu}g/100g$($9.76{\mu}gRE$)과 참기름 $11.41{\mu}g/100g$($1.90{\mu}gRE$)으로 측정되었다. 과일류 20개에서는 살구 생것 $2,280.35{\mu}g/100g$($380.06{\mu}gRE$)과 파파야완숙 생것 $242.57{\mu}g/100g$($40.43{\mu}gRE$), 파파야적숙 생것 $162.70{\mu}g/100g$($27.12{\mu}gRE$)으로 비교적 높은 베타카로틴 함량을 나타내었다. 거봉 생것, 청포도 생것, 켐벨얼리포도 생것의 경우 껍질을 포함하였을 때 베타카로틴 함량이 높게 측정되었다.

The content of ${\beta}$-carotene in agricultural foods, such as seasonings, tea, vegetables, cereals, nuts & seeds, oils & fats, and fruits, were quantitatively analyzed using reversed-phase HPLC with an UV/visible detector. Standard reference material (SRM) 2385 was used as a control material to validate measurement of ${\beta}$-carotene in this study. Recovery percentage and relative standard deviation of ${\beta}$-carotene in SRM 2385 were 102% and 1.73%, respectively. Vegetables and tea contained relatively high concentrations of ${\beta}$-carotene (young barley powder, $17,293.95{\mu}g/100g$; raw young barley, $2,755.15{\mu}g/100g$; dried green tea leaves, $13,671.85{\mu}g/100g$; green tea powder, $7,579.04{\mu}g/100g$). Contents of ${\beta}$-carotene in nuts & seeds as well as oils & fats ranged from $11.32{\mu}g/100g$ in almond products (roasted with salt) to $58.56{\mu}g/100g$ in perilla seed oil. Among 20 fruits, a high content of ${\beta}$-carotene was found in apricots (raw), which contained $2,280.35{\mu}g/100g$.
