Abstract

To evaluate a flower of rose, Rosa hybrids L. as a new food material, its chemical composition was analysed. The contents of crude protein, crude fat, crude ash and crude fiber in rose petals were 16.3, 2.9, 5.4, 16.1% on dry basis, respectively. Free sugars showed 74.3 mg/g of fructose, 49.6 mg/g of glucose and 16.6 mg/g of xylose. The contents of ${\beta}$-carotene and ascorbic acid were 205.2 ug/100 g and 129.5 mg/100 g, respectively. The major minerals of rose petals were K, P, Mg, Ca, Na and Fe, and among them K was the most abundant as 1,981.7 mg/100 g. The major amino acids were aspartic acid as 4,007.3 mg/100 g, glutamic acid as 1,114.8 mg/100 g, lysine as 672.6 mg/100 g and leucine as 661.0 mg/100 g. Fatty acids were mainly unsaturated fatty acids as 76.3%.

다양한 식품 소재의 창출을 목적으로 그 기초자료로서 장미의 화학성분을 조사하였다. 일반성분은 건물기준으로 조단백질 16.3%, 조지방 2.9%, 조회분 5.4%, 조섬유 16.1%였다. 유리당은 fructose, glucose, xylose가 검출되었으며, $\beta$-carotene은 205.2 ug/100 g, ascorbic acid는 129.5 mg/100 g이 함유되어 있었다. 무기질 함량은 K, P, Mg, Ca, Na, Fe순으로 다량 함유하며 K함량이 1,981.7 mg/100 g으로 가장 많았다. 구성 아미노산은 aspartic acid, glutamic acid, lysine, leucine 순으로 많았고, 그 함량은 각각 4,007.3, 1,114.8, 672.6, 661.0 mg/100 g이 었다. 지방산 조성은 76.3%가 불포화지방산이었으며, 그 중 linoleic acid가 58.2%이었다.
