Abstract

The purpose of this study was to examine the best cooking condition to decrease 4'-O-methylpyridonxine (MPN, ginkgotoxin) and increase the antioxidative effect. We also examined the change in color of ginkgo biloba seeds after different cooking methods and times. MPN content was decreased with an increase in the cooking time. For the reduction of MPN content, the most efficient cooking method was pan-frying. In particular, MPN content was largely reduced after 8 min of pan-frying. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity and total flavonoid content were increased after 11 min of pan-frying and this level was maintained until 14 min. The total phenolic compound content was maintained for up to 30 min by steaming and 11 min by pan-frying. Therefore, the optimum condition was established by pan-frying from 8 to 11 min.

본 연구에서는 조리조건에 따른 은행의 이화학적, 독성 및 항산화적 변화를 살펴보기 위해 삶기, 찌기, 볶기 3가지의 조리법과 각 조리법 별 5가지 조리시간을 설정하여 조리조건에 따라 조리된 은행에 대해 분석을 진행하였다. 은행의 외관 변화를 보기 위해 색도 분석을 진행하였고, 독성은 MPN 함량, 항산화적 변화는 DPPH radical 소거능과 총 페놀 화합물 및 총 플라보노이드 함량을 측정하여 비교하였다. 은행의 외관 변화를 감지할 수 있는 색도의 경우, 볶기가 가장 큰 변화를 보였다. 고온으로 인해 표면이 갈색으로 변하여 L 값이 감소하고 a값이 큰 폭으로 증가하는 경향을 보였다. MPN 함량은 볶기가 단시간 동안 큰 감소를 나타내었으며 특히 8분에서 MPN 함량이 큰 폭으로 감소하였다. DPPH radical 소거능은 11분간 볶은 은행에서 기능이 유의적으로 증가한 뒤 14분까지 생물 및 다른 조리조건에 비해 높은 값을 보였다. 총 페놀 화합물 함량은 30분 이내로 찌거나 11분 이내로 볶았을 때 그 함량이 유의적인 차이 없이 유지되는 것으로 나타났고, 총 플라보노이드 함량은 11분 동안 볶은 은행에서 그 함량이 유의적으로 증가한 뒤 14분까지 높은 값을 나타내었다. 이상의 결과를 바탕으로 조리시간 대비 변화가 크게 나타나는 조리법은 볶기인 것으로 나타났으며, 시간대비 변화가 가장 적은 조리법은 찌기인 것으로 나타났다. 또한 은행의 독성 함량 감소 및 항산화 활성 증가를 위한 최적의 조리 조건은 8분-11분간 볶는 것으로 분석되었다. 본 연구를 통해 서로 다른 조리조건에 따라 은행 속 독성 함량 및 항산화 활성이 변화하는 것을 확인할 수 있었으며, 이러한 변화 양상에 대한 분석은 추후 연구의 기초 자료로서 활용할 수 있을 것으로 사료된다.
