초록

본 연구에서는 식품으로서 활용범위가 점차 증가되고 있는 고들빼기 식품의 품질에 영향을 미칠 수 있는 여러 화학 성분과 기호성에 관계되는 특수성분을 조사하기 위하여 10월(A)과 12월(B) 2회에 걸쳐 채취시기별로 나누어 분석하였으며, 고들빼기에 함유된 항산화물질을 분석하여 가공식품으로 정착시키는데 필요한 기초 자료를 얻고자 하였다. 고들빼기의 채취 시기별 일반성분의 변화를 조사한 결과, 잎과 뿌리에서 채취 시기가 경과할수록 수분 함량과 조지방 함량은 공통적으로 감소하였으나, 섬유질, 단백질, 가용성무질소물 및 회분 함량은 증가하는 경향을 나타냈다. 무기질은 채취 시기가 경과할수록 잎의 Mg과 Na를 제외하고는 모든 시료에서 공통적으로 증가하는 경향이었다. Vit. C와 Niacin은 채취 시기가 경과할수록 잎과 뿌리 모두에서 공통적으로 감소하는 경향이었으나, Vit. $B_1$, $B_2$는 소량 증가하는 경향을 보였다. 고들빼기 잎과 뿌리의 주된 유기산은 구연산, 사과산 및 주석산이 검출되었고, 시기별로 성분함량의 차이는 보이지 않았다. 주요 구성아미노산은 잎과 뿌리 모두에서 isoleucine과 leucine이었고, 채취시기가 늦을수록 구성아미노산 함량은 증가하였다. 고들빼기의 잎과 뿌리에 함유된 유리당은 fructose, glucose, sucrose, maltose 등 4개의 당이 확인되었고 총 유리당 함량은 채취 시기가 늦을수록 증가하였다. Phenol화합물은 arbutin, catechin, chlorogenic acid, p-coumaric acid 등 4개의 성분이 확인 되었으며, 잎보다 뿌리 함량이 높은 것으로 나타났으며, 채취시기가 늦을수록 그 함량이 증가하는 것으로 나타났다. 고들빼기 항산화력은 잎보다 뿌리의 항산화력이 더 강한 것으로 나타났으며, 채취 시기가 늦을 수 록 더 강한 것으로 나타났다.

This study analyzes the chemical composition and thiobarbituric acid reactive substance levels of Godulbaegi (Youngia sonchifolia M.) depending on collection time. The moisture and crude fat content in leaf and root decreased, while crude fiber, crude protein, carbohydrate, and ash increased with increases in collection time. The mineral elements tended to increase in each sample with increases in collection time. The content of vitamin B increased as collection time increased. Vitamin C content was approximately five times higher in the leaves than that in the roots. Total amino acids in leaf and root increased considerably as collection time increased content of phenolic compounds in root were higher than that in the leaf and these contents increased. Antioxidant activity of Godulbaegi was higher in the root than in the leaf and increased as collection time increased.
