볶음처리한 새송이버섯의 마이크로웨이브 추출조건, 즉 에탄올 농도, 추출시간 및 마이크로웨이브 power에 따른 품질특성을 살펴보았다. 총 페놀성 화합물 함량, 전자공여능 및 pH 1.2에서의 아질산염소거능은 50% 에탄올로 추출한 경우 높게 나타났다. SOD 유사활성은 75% 에탄을 농도로 추출하였을때 가장 높은 활성을 나타났다. 가용성 고형분 및 총 페놀성 화합물 함량은 추출시간이 증가할수록 증가하다가 7분일 때 가장 높게 나타났으며, 전자공여
This study was performed to investigate the changes in quality properties of extract from roasted Pleurotus eryngii by microwave-assisted extraction (MAE). MAE was carried out under different conditions including ethanol concentration, extraction time and microwave power. Total phenolics compound contents, electron donating ability (EDA) and nitrite-scavenging ability at pH 1.2 were high at 50% ethanol concentration. Superoxide dismutase (SOD)-like activity was high at 75% ethanol concentration. Soluble solid and total phenolics compound content decreased as extending extraction time up to 7 min. EDA decreased as increased extraction time. SOD-like activity and nitrite-scavenging ability were not significantly different. The highest soluble solid content, total phenolics compound content and EDA were obtained at 100 W extraction of microwave power. SOD-like activity was high at 25 W. But microwave power did not significantly affect the nitrite-scavenging ability.
