Abstract

To make the germinated buckwheat tea, soluble solid contents, total flavonoid contents and organoleptic properties were investigated under various steaming time and drying temperature. The optimum condition of soluble solid contents were 6.93 min of steaming time and 73.59$^{\circ}C$ of drying temperature. Total flavonoid contents were maximum under the condition of 5.22 min of steaming time and 79.05$^{\circ}C$ of drying temperature. The optimum condition of overall palatability was 6.00 min of steaming time and 77.33$^{\circ}C$ of drying temperature. The optimum ranges of soluble solid contents, total flavonoid contents and overall palatability of the tea were 5.4∼7.0 min of steaming time and 75∼8$0^{\circ}C$ of drying temperature. The values expected in the optimum ranges were also similar to the experimental values.

메밀순을 이용한 침출차를 제조하고자, 증숙시간과 건조온도를 달리 처리하여 가용성 고형분 함량, 총 플라보노이드 함량 및 관능적 특성을 살펴보았다. 메밀순차 침출액의 가용성 고형분 함량은 증숙시간 6.93 min 및 건조온도 73.59$^{\circ}C$에서 최대값으로 나타났으며, 총 플라보노이드 함량은 증숙시간 5.22 min 및 건조온도 79.05$^{\circ}C$에서 높은 함량을 나타내는 것으로 나타났다. 메밀순 침출차의 전반적 기호도에 대한 높은 관능평점은 증숙시간 6.00 min 및 건조온도 77.33$^{\circ}C$인 것으로 나타났다. 가용성 고형분 및 총 플라보노이드 함량이 높고 전반적인 기호도도 우수한 조건은 증숙시간 5.4∼7.0 min 및 건조온도 75∼8$0^{\circ}C$로 예측되었으며 최적 조건에서의 예측된 관능평점은 최적 조건에서 실제 실험한 결과와 유사하였다.
