쌀은 무엇인가? | 쌀은 아시아 국가의 주요 식량자원으로서 생활에 필요한 에너지 공급을 위한 영양원으로 인식이 되었으나, 최근 쌀의 생리적 효능이 다양하게 규명되면서 쌀의 고부가가치화를 위하여 쌀의 2차, 3차 기능성을 증진시키는 방향으로의 연구들이 활발하게 진행되고 있다. 즉 품종개량을 통하여 기능성이 강화된 신품종 개발 [1-5]과 가공성 증진 병용 [6,7]에 의한 건강증진용 쌀가공 식품의 다양화 그리고 생리활성 효능 검증을 통한 건강기능성 신소재로서의 개발 [8-10] 등이 진행되고 있다. | |
일반현미 배아 (NG)와 큰눈자미 배아 (KG)의 phytosterols 함량 측정결과는 어떠한가? | 일반현미 배아 (NG)와 큰눈자미 배아 (KG)의 phytosterols 함량 측정결과는 Table 2에 나타내었다. β-sitosterol의 함량은 NG가 0.83 mg/g, KG가 0.80 mg/g로 나타났으며, cycloartenol의 함량은 NG가 0.28 mg/g, KG가 0.27 mg/g로 유의적인 차이가 없었다. Campesterol의 함량은 NG가 0. | |
쌀의 품종 개량을 통하여 얻은 신품종에는 무엇이 있는가? | 즉 품종개량을 통하여 기능성이 강화된 신품종 개발 [1-5]과 가공성 증진 병용 [6,7]에 의한 건강증진용 쌀가공 식품의 다양화 그리고 생리활성 효능 검증을 통한 건강기능성 신소재로서의 개발 [8-10] 등이 진행되고 있다. 이러한 노력의 결과 품종 개량을 통하여 아밀로오스 함량이 높은 고아미 2호 [5], 일반 품종 보다 배아가 큰 거대배아미 [3] 및 안토시아닌 색소 함량이 증대된 자미 품종 [1,2,4] 등이 육종되었고, 이들 쌀 품종을 활용하여 다양한 종류의 쌀가공 식품 개발 [11-13] 및 쌀의 건강기능성 식품 소재화 등이 이루어지고 있다. |
