Abstract
This study was attempted to investigate the occurrence and the characteristics of ascorbic oxidase in cucumbers. Ascorbic acid oxidase was isolated from cucumbers and concentrated using ammonium sulfate precipitation. The results of this study are as follows ; 1) Ascorbic acid oxidase activity was detected in whole cucumber homogenate. 2) Highest amounts of ascorbic acid destroyed after 10 minutes' incubation of ascorbic acid oxidase with its substrate. 3) The optimum pH and temperature of this enzyme were found to be pH 6.5 and
본 연구는 오이의 추출물에서 Ascorbic acid oxidase 활성의 존재유무를 검토하고 이 효소의 특성을 규명하여 Ascorbic acid의 손실을 최소화하는 과채류의 조리, 가공조건을 설정하는데 도움이 되고저 시도 되었다. 오이에서 Ascorbic acid oxidase를 분리해 내어 그 특성을 연구한 결과 시간의 변화에 따른 Ascorbic acid oxidase의 활성은 처음 10분 동안 Ascorbic acid 감소량이 가장 현저하였으며 Ascorbic acid oxidase의 최저 pH는 6.5로 나타났다. 또한 온도의 변화에 따른 Ascorbic acid oxidase의 활성은
