반응표면분석법을 이용하여 둥굴레 근경의 증자 및 볶음조건에 따른 추출물의 총 페놀성 성분, 전자공여능 및 아질산염 소거능의 변화를 모니터링하였다. 중심합성계획법에 따라 증자시간, 볶음온도 및 볶음시간을 달리하였을 때 회귀식의 는 총 페놀성 성분, 전자공여능 및 아질산염 소거능(pH 3.0)에서 각각 0.9356, 0.9578 및 0.9436으로 수준에서 유의성이 인정되었다. 총 페놀성 성분의 최대값은 증자시간 135.59분, 볶음온도 및 볶
Response surface methodology (RSM) was applied to monitor the effects of steaming and roasting conditions of Polygonatum odoratum roots an total phenolics content, electron donating ability (EDA) and nitrite-scavenging ability (NSA) of the extract. In steaming and roasting processes based on the central composite design. with variations in steaming time , roasting temperature and roasting time , coefficients of determinations were 0.9356 (p at 135.59 min of steaming time, of roasting temperature and 43.47 min of roasting time. The maximum value of EDA was in 108.98 min, and 48.86 min. The maximum value of NSA (pH 3.0) was in 162.80 min, and 31.97 min, respectively. Total phenolics content of the extract was influenced by heating conditions in the order of roasting temperature, steaming time and roasting time. While EDA and NSA were appreciably influenced by roasting time, followed by roasting temperature and steaming time.
