둥굴레 근경의 증자 및 열처리 중 수용성 고형분 및 Pb, Cd 제거율의 변화를 확인하기 위하여 반응표면분석(RSM)을 활용하였다. 중심합성계획법에 따라 증자시간( min), 볶음온도() 및 볶음시간( min)을 달리하여 16구간으로 제조된 시료의 수용성 고형분 함량, Pb 및 Cd 제거율을 측정하고 회귀분석을 실시하였다. 예측된 가용성 고형분의 최대값은 이었으며, 이때의 증자 및 볶음조건은 증자시간 65.24분, 볶음온도 및 볶음시간 37
Response surface methodology(RSM) was applied to monitor the elimination rate of heavy metals(Pb, Cd) and soluble solids depending on the steaming and roasting conditions of Polygonatum odoratum roots. Experiments of 16 different steaming and roasting conditions based on a central composite design for steaming time( min), roasting temperature(), and roasting time( min) were conducted, thereby predicting the steaming and roasting conditions for the maximal responses; soluble solids() at 65.24 min, and 37.58 min; Pb removal rate() at 71.23 min, and 24.35 min; Cd removal rate() at 160.89 min, and 15.81 min, respectively. The optimum conditions estimated by RSM for the maximized values of soluble solids and heavy metal elimination rates were min of steaming time, of roasting temperature, and min of roasting time, respectively. These estimated values were in agreement with those measured by real experiments.
