초록

본 연구는 증절간 고구마 제조를 위하여 냉풍건조 방법을 이용하여 건조조건별 증절간 건조 고구마의 건조특성, 물성 및 관능적 특성을 연구하였다. 건조시 수분함량은 $25^{\circ}C$ 48시간에서 4.98%로 가장 낮은 수치를 보였고, 색차에서 건조온도가 낮을수록, 건조시간이 짧을수록 L값이 높아졌으며 a, b, ${\Delta}E$값은 건조온도가 높을수록 건조시간이 길어짐에 따라 증가하는 경향을 보였다. 가용성 고형분은 건조 조건별로 19~70 $^{\circ}Brix$의 범위를 나타내었고, 환원당은 98.7~194.75 mg/g 범위를 나타내었으며, 불성측정에서 경도는 $25^{\circ}C$, 48시간에서 23.88 $kg_f/cm^2$로 가장 높은 수치를 나타내었으며, 탄성과 응집성은 91.15, 98.36%로 가장 높은 수치를 나타냈다. 관능평가에서 $10^{\circ}C$, 40시간, $25^{\circ}C$, 24시간에서 색, 향미, 맛, 조직감, 전반적인 기호도에서 가장 높은 평가치를 나타내었으며, 반응표면분석을 통한 증절간 고구마의 최적 건조조건을 예측한 결과 $19^{\circ}C$, 건조시간 32hr으로 예측되었다.
