Abstract

This study investigated the characteristics of taste and flavor in various wintering-radish extracts using electronic sensors. Sourness showed the highest sensor value (6.9) in hot brewed extracts of white radish part. Saltiness showed the highest sensor value (8.0) in cold brewed extracts of green radish part. Umami showed the highest sensor value (8.3) in hot brewed extracts of white radish part. Sweetness showed the highest sensor value (6.8) in cold brewed extracts of green radish part. Bitterness showed the highest sensor value (7.5) in espresso extracts of green radish part. A total of 16 volatiles were identified using electronic nose. Among these volatile compounds in radish extracts, methanethiol was found to be the predominant volatile compound. These sensory characteristics in radish extracts can be used as basic research data in the food industry.

본 연구는 전자 센서를 이용하여 다양한 추출방법에 따른 무 추출물들의 향미 특성을 조사하였다. 무의 신맛은 무 흰색 부위의 열수 추출물이 6.9의 센서 값을 나타내어 가장 높았다. 신맛은 8.0의 센서 값을 나타내어 무 초록색 부위의 콜드 브루 추출물이 가장 높았다. 감칠맛은 무 흰색 부위의 열수 추출물이 8.3의 센서 값을 나타내어 가장 높았다. 단맛은 무 초록색 부위의 콜드 브루 추출물이 6.8의 센서 값으로 가장 높은 값을 나타내었고, 쓴맛은 무 초록색 부위의 고온 가압 추출물이 7.5의 센서 값으로 가장 높은 값을 나타내었다. 전자코를 이용하여 무 추출물들에서 총 16개의 휘발성 향기성분을 확인하였다. 무 추출물 속 휘발성 향기성분들 중 methanethiol이 주요한 향기성분으로 확인되었다. 본 연구에서 확인된 결과들은 무 추출물의 향미 특성에 대한 기초 연구 자료로 활용될 수 있을 것으로 판단된다.
