도라지 종자의 영양학적 특성 평가 = Evaluation of Nutritional Characteristics of Platycodon grandiflorum Seeds

다국어 초록 (Multilingual Abstract)

In this study, proximate composition, crude fiber, reducing sugar, free sugars, organic acids, minerals and amino acids of Platycodon grandiflorum seeds were analyzed to evaluate its nutritional value. Moisture, crude protein, crude fat, crude ash and carbohydrate contents of seeds were 6.97, 26.05, 27.46, 3.78 and 35.74%, respectively. Crude fiber of 6.31% and reducing sugars of 1.54% were also determined. Sucrose(1,661 mg/100 g) and lactic acid(1,224 mg/100 g) were most abundant free sugar and organic acid, respectively. Both phosphorus and potassium were main minerals that contained more than 700 mg in 100 g seeds. Amino acids analysis of 100 g seeds showed that glutamic acid(3.45 g), arginine(2.51 g), aspartic acid(1.66 g), leucine(1.29 g), lysine(1.10 g), alanine(1.05 g) and glycine(1.04 g) were abundantly contained in order, while others were less than 1 g.

본 연구에서는 도라지(Platycodon grandiflorum A. DC) 종자의 영양학적 특성을 평가하기 위해 일반성분, 조섬유, 환원당, 유리당, 유기산, 무기질 및 아미노산 함량을 분석하였다. 종자의 수분, 조단백질, 조지방, 조회분, 탄수화물 함량은 각각 6.97, 26.05, 27.46, 3.78, 35.74%였으며 조섬유 함량은 6.31%, 환원당 함량은 1.54%이었다. 종자에 존재하는 유리당으로는 sucrose가 1,661 mg/100 g, 유기산으로는 lactic acid가 1,224 mg/100 g 으로 가장 풍부하였으며, 인과 칼륨이 주요 무기질로서 700 mg/100 g 이상 존재하였다. 종자 100 g에서의 아미노산 조성을 분석한 결과, 글루탐산(3.45 g), 아르기 닌(2.51 g), 아스파르트산(1.66 g), 루신(1.29 g), 라이신(1.10 g), 알라닌(1.05 g), 글리신(1.04 g) 순이었 으며 그 외의 아미노산은 1 g 이하로 존재하였다.
