Abstract

The functional properties of Hericium erinaceus were analyzed. The crude protein content was 8.01%. free sugars were mainly composed of glucose(47.09 mg%) and fructose(34.65 mg%), but sucrose and maltose were not detected. The free amino acids were mainly glutamic acid(1,468.12 mg%), alanine(716.07 mg%) and threonine(643.95 mg%) in Hericium erinaceus. It doesn't difference between water and ethanol extract on soluble solid content. Comparing minerals of extracts from Hericium erinaceus, water extract showed higher contents than ethanol extract except for I This tendency is similar to superoxide scavening activity and electron donating activity. But phenolic compounds, ethanol extract was higher than water extract. In comparison of water and ethanol extract of Hericium erinaceus, as a whole water extract was excellent.

노루궁뎅이 버섯 및 그 추출물의 일반적인 식품의 성분과 기능적 특성을 조사하였다. 그 결과 노루궁뎅이 버섯의 조단백질은 8.01%로 나타나 단백질의 함량이 높은 것으로 나타났으며, 유리당은 glucose 47.09 mg%, fructose 34.65 mg%의 순으로 나타났으며 sucrose와 maltose는 나타나지 않았다. 유리아미노산은 glutamic acid alanine, threonine과 serine의 순으로 많은 함량을 나타내었다. 가용성 고형분 함량은 용매에 따른 차이가 없는 것으로 나타났으며, 무기질 함량은 칼륨을 제외하고는 물 추출물이 에탄올 추출물보다 높은 함량을 나타내었으며, superoxide 라디칼 소거능에서도 유사한 경향을 나타내었다. 페놀함량에서는 오히려 에탄을 추출물이 조금 높게 나타났으며 전자공여작용은 물 추출물(59.1 unit)이 에탄올 추출물(33.8 unit)보다 훨씬 높게 나타났다. 이상의 결과에서 용매에 따른 추출에서 물 추출물이 용매 추출물보다 전반적으로 기능적 특성을 가진 성분이 많이 추출되는 것으로 사료된다.
