Abstract

Soy sprout is a traditional food in Korea. It has been a source of protein, lipid and vitamin etc. as cooked and fresh vegetable supplying throughout the year. Soy sprouts of five soybean cultivars were analyzed fatty acid composition and dietary fiber contents. The compositional analysis confirmed that soy sprout contained five major fatty acids(16:0 palmitic, 18:0 stearic, 18:1 oleic, 18:2 linoleic and 18:3 linolenic). Fatty acid levels in soy sprout were not significant statistically between fresh and boiled soy sprout, the result support a conclusion that boiling treatment could not affect the fatty acid composition in soy sprouts. Fatty acid levels in whole and cotyledon part of soy sprout were not changed during sprout production, whereas the content in hypocotyl increased by approximately 13.2% of total unsaturated fatty acid compared to whole soy sprout. In case of dietary fiber, boiled soy sprouts showed higher contents than in fresh soy sprouts. These changes were associated with an increase in the mean level of insoluble dietary fiber expecially. Fatty acid levels and dietary fiber contents varied with soybean cultivars suggesting chemical composition of soybean seed was important to soy sprout characters.

전통식품인 콩나물의 고부가가치화를 위한 우량 나물콩 품종 육성의 기초 자료를 제공하고자 특성이 다른 5종의 장려품종 나물콩으로 재배한 콩나물의 지방산 및 식이섬유 함량을 분석한 결과는 다음과 같다. 1. 생콩나물과 데친 콩나물의 지방산 조성은 큰 차이가 없어 가열 처리가 지방산 조성에는 영향을 끼치지 못하였다. 2. 전체 콩나물과 콩나물의 자엽 부위 지방산 조성은 원료콩과 비슷하였으나 배축 부위는 원료콩에 비해 포화지방산 함량이 높았으며 변이도 자엽 부위보다 컸다. 3. 가열 처리된 콩나물이 생콩나물보다 식이섬유 함량이 높았다. 4. 지방산 조성과 식이섬유 함량은 품종별로 차이가 있었다.
