천마를 건강기능식품가공소재로서 효율적으로 이용하기 위해서는 가공 중 일어날 수 있는 유효성분의 파괴를 최소화하는 것이 필요하다. 본 연구에서는 전처리 과정중 추출조건별로 천마의 유효성분 함량 및 항산화적 특성을 반응표면분석법으로 모니터링하여 최적 추출조건을 설정하였다. 천마 열수 추출물의 vanillyl alcohol 함량은 추출온도 , 추출시간 2.64 hr 및 시료에 대한 용매비 15.16 mL/g에서 가장 높은 함량을 나타내었고, vanil
In order to reduce the damage of effective component during processing, we carried out hot-water extraction monitering in Gastrodia elata Blume by response surface methodology. The extraction con야tions for vanillyl alcohol, vanillin and coumarin were optimized at 91.07, 93.73 and , for 2.64, 2.58 and 3.84 hr, at the concentration of 15.16, 21.56 and 19.88 mL/g, respectively. The optimal condition for extraction of total phenolics was acheved at , 3.20 hr and 18.63 mL/g. This study elicited regression formula for each variable, and superimposed the total optimal conditions of extraction for effective compounds and optimal condition for antioxidant characteristics dividing processing factors. It is shown that the predicted result under the extraction condition as follows: extraction temperature for , extraction time for , and solvent volume of of sample.
