The quality characteristics of yenipsambab prepared using various amounts of red, green, and black pigmented rice (0, 10, 20, and 30% added) were investigated. The pH of the cooked rice of yenipsambab decreased significantly as the amounts of pigmented rice increased. The Hunter's color L value decr...

우리의 주식인 쌀에는 어떤 생리활성 성분이 함유되어 있는가? | 우리의 주식인 쌀에는 tocopherol, tocotrienol, γ-oryzanol 등의 항산화성분을 비롯하여 phytic acid, 식이섬유, γ-aminobutyric acid 등 다양한 생리활성 성분이 함유되어 있다(2,3). 쌀은 과거로부터 우리나라의 중요한 식량자원으로 경작지의 대부분을 차지하여 왔으며 생산량에 큰 관심과 노력을 집중하여 왔다. | |
특수미 중에서 유색미가 갖고 있는 천연색소의 종류는? | 과피의 색이 적갈색에서부터 흑자색에 이르는 다양한 품종의 유색미들은 일반미 품종들에 비해서 미강층 추출물의 항산화 활성이 우수하며(5), 이들이 가지는 항산화 성분으로서 cyanidine 3-O-β-D-gluciside 및 peonidine 3-O-β-D-gluciside 등이 보고되어 있다(6-8). 유색미는 안토시아닌과 탄닌이라는 천연색소를 가지고 있는데, 안토시아닌계 색소는 항산화 기능과 발암억제, DNA 손상 억제 기능 등 기능성이 높아 식품학적으로 가치가 높다고 보고 되어져 있고, 탄닌계 색소는 유해 중금속의 제거 및 변이원 물질 생성을 억제 시킨다는 보고가 있다(9-10). 유색미의 색소는 혈관의 노화를 방지하고 자외선 차단 효과가 있는 색소로 유색미를 활용하여 혈압강하 의약품 연구, 자외선 차단 화장품 소재 연구, 유색 적주 등의 식품개발 연구 등이 보고 되어 있다(11). | |
유색미는 백미에 비하여 우수한 것으로 알려진 점은? | 유색미의 색소는 혈관의 노화를 방지하고 자외선 차단 효과가 있는 색소로 유색미를 활용하여 혈압강하 의약품 연구, 자외선 차단 화장품 소재 연구, 유색 적주 등의 식품개발 연구 등이 보고 되어 있다(11). 유색미는 일반미(백미)와는 달리 현미 상태로 도정하여 사용하기 때문에 백미에 비하여 식이섬유, 비타민, 무기질 등의 영양소 함량이 우수한 것으로 알려졌다(4). 이처럼 유색미는 색소성분이나 쌀겨로부터 유래한 생리활성 물질을 함유하고 있어 기능성 식품으로 가공, 개발할 가치가 높은 식품소재로 사료된다. |
