Abstract

This study was carried out to investigate the food value of K. pictus sprouts. The total ginsenoside content was 67.4 mg/kg. Including Ginsenoside Rg1, a total of five different types were detected by the experiment. The total phenol content was 33.77 mg/100 g. Including seven different type of essential amino acids, the total amino acid content of K. pictus sprouts was 33,744 mg/100 g. The results of the analysis of the free amino acid content showed that the total bitterness was much higher than the total sweetness. From the above results, the food characteristics of K. pictus sprouts could be determined. To improve their consumption, their bitterness must be reduced.

음나무 순의 성분 분석을 통하여 식품학적 가치의 확인과 가공 식품으로서의 개발 가능성을 모색하고자 하였다. 음나무 순의 식품학적 특성을 알아보기 위해 일반성분, 무기질, 구성 및 유리 아미노산을 분석하고, 관능 평가를 실시하였으며 음나무 순의 기능성을 입증하기 위하여 조사포닌, 진세노사이드, 총 페놀 함량 및 항산화 활성을 측정하였다. 총 진세노사이드 함량은 67.4 ppm으로 Ginsenoside Rg1을 비롯하여 총 5종이 검출되었으며, 총 페놀 함량은 87.78 mg/100 g, 항산화 활성은 82.60%로 나타났다. 음나무 순에는 필수 아미노산 7종을 포함한 총 구성아미노산 함량이 33,744 mg/100 g으로 그 중 glutamic acid의 함량이 가장 높고 aspartic acid>leucine>lysine 순 이었다. 유리아미노산 분석결과 감칠맛과 단맛을 내는 성분의 총함량보다 쓴맛을 내는 성분의 총함량이 높게 나타났다. 이상의 결과로 음나무 순의 식품학적 특성을 알 수 있었으며, 소비 증진을 위하여 쓴맛을 개선한 기호성 높은 가공 제품의 개발이 요구된다.
